need 5eat upgraded turbo info [Archive]

tyring to find the best set-up for my own liking. i am tired of searching for dyno plots etc. so can i get some love from my 5eat brothers? looking for feedback on 18g, 20g, avo 380, 40bb etc. i am not interested in the vf40-18g. just not worth the effort imo. i want a 12sec. set-up w/o doing an sti conversion or running meth.

thanx, mike

18g with supporting mods is around 280-290 whp see MBLOCK66 he may be selling his setup. With a decent launch that would be in the 12's

TRS is running the TDC 40BB and I think hit 278 whp on a dyno, but had very good spool. I'd imagine his car would hit 12's also.

20g would be upwards of 295 whp with slightly more lag, but would get you in the 12's most definately.

AVO450 See below post, he dynoed 277 whp

You should know that every dyno is different, and 5eats dyno especially weird.

Were you ever running a 20g, for some reason I thought when you blew your tranny it was with a 20g.

345 WHP, 320Wtq w/meth but also crippled with CA91. Blouch Dominator III (bolton Gt30). So far so good, 18k on turbo. VB upgrade about 700 miles ago. We'll see how long tranny goes for.

Nope, I went from stock LGT turbo to 18G then meth. Stock 5EAT seems to worked fine when hp is under 260, but don't take my words for it. Get a cooler for your 5EAT.

for some1 that does not want to do the VB upgrade from IPT, what turbo do u suggest?

AKLGT

07-30-2007, 02:30 AM

well, if you want to run 12's consistently then you definitely need to beef up the tranny. i'm still waiting for the big boys to get to the track to see the diff b/w various turbo set ups on our 5EATs. of course, kinda hard to completely tell since we're all in diff climates and driver input also makes a difference.

FP 20g here: 320whp/290wtq.

I highly recommend trans cooler and VB for the 5EAT if you upgrade to this power level or more.

it's not just a shift kit. it reinforces the tranny. too much power and you'll experience gear and tranny slippage. i upgraded mine out of necessesity but WOW! what a difference! others have done the same, waited til it was necessary, however, now knowing the difference, i can't help but wonder how much better the car would have responded with my previous gutted stg 2 set up.

LOL> it's ok, cause my dyno'd 238 awhp (PDX) 5eat is finally running 12's. ;) of course, that was in hotter temps than the car was used to, not boosting over 16 psi (i usually boost at 21 psi and taper to 17), and major major heat soak (not to mention the damn fan that blew up on my intercooler!). numbers only get you so far... and still to this day, no one has been able to beat my times in my own car when it comes to the drag strip. autocross however, that's a different story.

mike! LACR last day was this weekend I think. We are going to have to travel further to race. Still waiting on the tranny to come back. Its in pretty bad shape, but harman motive did save my crankshaft.:eek: Turbos with low rpm peak boost is definitely not good for the tranny. running the twinsroll vf37 is great, if you upgrade the 5eat. If you are going to try to trap 12's, you need the IPT VB upgrade. You will need a pretyt big turbo to get you to 12's, like a sz55 if you want bolt on. If you don't mind going rotated, get the gt30 rotated kit. Keep in mind you will have to power brake your car pretty hard to get a good launch to spool the turbo. Too much power braking will lead to broken axles and blown diffs over time. My opnion is that you need a quick spool to get 5eat's to get to your goal. Jersey Glock has a great setup. 18g with meth ftw.

Thanks Hybrid22L. I'm saving up for the SZ55 upgrade. I'm staying with Perrin TMIC. :)

07-30-2007, 07:08 PM

I'm happy with my setup... bolton gt30 + meth :D. Our gas sucks, but oh well, we still get to live in Sunny Socal, no? I do wish i had gone rotated tho.

I dunno if i'm gonna make august 11, but i'll go for the event after that. I need to give HM time to get the mustang up, then head back for another dyno run to check out the tune. Gonna try to get a road tune to see if we can track down what's wrong this week I hope.

Even sans hard launch, i should have pretty decent trap speeds... That's what i'm going for till i get the hang of this.

And Quan, I made LACR last wednesday. I wish i could get a chance to redeem myself.

SZ49 "fatboy" on pump gas
With a few extra bolt on's 350whp is def do-able;)

Go ahead & do the VB upgrade

many of the turbo's you mention in your original thread are simply not large enough without meth to put you solidly into the 12's

07-31-2007, 08:59 AM

i haven't seen any 1 post who has this kit on an 07. i think less than a dozen of us are tuned. i havn't looked that hard either. i wanna keep my top mount and try and get 300/300 and run 12's. i will never actually track the car, maybe once to see what the car can do. i want that power for on the roll runs. i think the 40bb with meth will get me close.

wukindada

07-31-2007, 09:32 AM

300/300 will not get you consistant 12's with the 5EAT. With perfect conditions yes, but remember dyno #'s on our cars is just a joke anyways......
Anyone that put's you on a dyno with a TMIC setup & tell's you you are hitting those #'s with the 5EAT is just plain full of Sheeeeeiiiiite!!

You could go with a SZ49, Meth & a Perrin TMIC but you would def not be getting the most out of that turbo by retaining the TMIC setup.

07-31-2007, 09:43 AM

does the SZ49 come with an optional LGT flanged compressor housing?

i ran consistent 12.70's-12.80's with my bugeye wrx. stock tmic and a vf30 that was sent to deadbolt for a little work. the ej20 had forged pistons installed for higher boost. i ran 20psi-17.5psi on the wrx. how ever the wrx had 4:10 gears, still kind find what the lgt has. i am sure with either the avo 380 or the 40bb w/meth i will run 12's. then again who knows, maybe i wont. i would be very happy with a 12.80 car

wukindada

07-31-2007, 09:51 AM

with a MT correct....

Nope it doesn't .......
My brain is thinking it's monday:rolleyes:

Vacations screw with your brain;)

You would need to @ least do a STI swap & then you could run a aftermarket STI TMIC.

For a direct bolt on you are really limited & I really do not think there is anything that will put you solidly into the 12's:(:(

The STI swap is relatively cheap & it's a fairly easy install, I'd say go that way

poopy

07-31-2007, 09:56 AM

i just don't like the look of the sti engine bay. it looks like a science project. besides i have to fool the chik into thinking the car was only tuned and exhaust were done. need that stock look:lol:

wukindada

07-31-2007, 10:03 AM

I'd suggest a Perrin TMIC then & a TD06 20g with meth you will be very close to your goals.

Get about every bolt on you can for the car on top of that & it should be a 12.8-12.9 sec car:):):)

07-31-2007, 10:16 AM

the wrx was a 4eat. and i dont wanna hear any b.s my wrx was well known in the ny area. all runs were made at iether englishtown or L.I. raceway, which is no longer open. the car was just a freak.

nope. just a cooler. i would have to stand on it like crazy but it i couls launch at 18psi. now if it was 90 degrees i couldn't launch like that. the turbo had a bb center p&p etc. i am telling you it was just a freak and the tuners couldn't figure it out. other 4eat's in the area followed my lead and never saw the same results. i did blow my rear-diff on a launch:lol:

i just talked to my tuner, who also owns a subaru dealership, he told me to wait and STAY AWAY FROM BLOUCH. i trust him, so maybe the avo 380 or 420 is my new option.

i went with the STI swap because to get the same power with LGT bolt on's woulda cost me twice that. $1100 for all parts and hardware. but then i ran into a snag... gears slipping and didn't like the tune. VB upgrade and PDX maps fixed that, but not without spending another $1500 for it. i probably would have been just fine had i not spent the entire previous summer launching the car at 3000+ and tracking it. no tranny cooler then either. now i have a tranny cooler and VB upgrade, tuning is good and i'm happy. few more things to tweak and by end of summer, should be a 12.8 sec 5EAT. :)

just checked and I have a fractured flexplate... i was getting a loud clatter coming from the TC area and pulled the plug on top of motor to take a look... the flexplate is rubbing on something and after further inspection notice a few stress factures. weird as the car has been running great. too much torque to the flexplate? any ideas?

plan on replacing flexplate next week.. do they make an aftermarket one?

^^^so your IPT tranny broke? I am having major problems with my VB so I sent it back up to them. The car was struggling to down shift and shift gears between 3rd and 4th. I am thinking worst case, is towing my car to IPT in jersey to get a built tranny but if you are having problems with it, I dont know if it is worth it.

Hmm. If your car is driveable why don't you just drive to NJ and have them make a few tweaks to your VB, test drive it. Then make a few more tweaks if it is not yet perfect.

If the tech seems to think line pressure is not the problem and your clutch packs are shot you can then just order the parts for the rebuild and have your friend install them :)

acooper5

11-15-2007, 01:58 PM

my friend isnt a tranny specialist and he is honest about what he can and cant do. I would rather have IPT do it. The car is not driveable, it wouldnt shift out of 1st or 2nd gear and felt like somebody was stepping on the brakes while I was applying the gas. Essentially I had to push the car to middle throttle just to get it to go 15 mph. So I towed in back to my buddies shop and sent the VB back up to IPT. It wasnt doing this before I took my VB out the first time, it was only slipping, thats why I think most definitely it is the VB now.

not sure what happen as I will need to pull the tranny out and inspect. The flexplate is cracked most likely for tq and hp.. I have done very little power braking so i doubt it craked from that. outside of the flexplate cracked the tranny seems to be fine.

any other ideas why the flexplate would crack other than TQ and HP?

should I start another thread? thanks all

join the club. I shattered my flexplate and destoyed the ipt tc. It was due to the tc bolts coming loose. IPT fault and they replaced free of chrage. Make sure you use locktite on those blots. Also, it was from the vb shifting too hard. it was slamming into gears and that was what caused the tc bolts to come loose. Runs like a charm now and no chattering. Make sure the vb is adjusted correctly on the fully built ipt trannies. Jersey Glock and I had the same problem. PM me if you have anymore questions.

Only if you have a vb upgrade. If you don't have a vb upgrade, do not go twinscroll. Jerseyglock is making the same power as me with an 18g, 93 octane with meth. So even with that kind of setup, you need a vb because the peak torque will destroy the clutch packs in between shifts. Imagine burning the clutch in every gear on a manual gear. Its ok to go twinscroll on a stock 5eat if you go with a bigger turbo like a 20g or bigger, since peak boost will be later.

jim1969

11-27-2007, 08:38 AM

I would think that upgraded VB or not, the twinscroll is going to hit faster in the lower gears and be more of an issue than the 18g, 20g, AVO380, etc.

mikeyan

11-27-2007, 10:04 AM

problem is, we dont' have very direct size turbo comparisons for twinscroll versus single scroll...

only thing i've seen is 30r class turbo's in twinscroll versus single, and for them, the twinscroll advantage is really minimal (Maybe 200rpm, probably less).

Yeah I would obviously get the VB upgrade first if I did the twinscroll. I am really interested in your setup, the PE1825 sounds like a fun turbo.

I remember reading that your car dynoed at 311 whp and from what I heard 5eats dyno at least 10% less than a MT. So your car is probably making more like 320-330 whp with insane spool because the turbo is getting flashed by the TQ converter.

I just do not know if the VB upgrade is enough to sustain the life of the transmission :rolleyes:

Also a twinscroll would be a little more costly than say using a wrx fitment 20g or FPGreen, Sz49 etc.... Although I have seen some great packages lately that have the entire setup (Excluding FMIC and Fueling) for between 1000-1700 on Nasioc and here. Which obviously does not include the PE 1825 clone work by deadbolt :(

i have to agree with Mike. The diffrence from a twinscroll turbo to a well made single scroll turbo is very minimal. The extra 200 rpm does make a huge diffrence in auto-x. Daily driven, you probably won't notice the difference. Its all in the tune.

I'm curious as to what a "VB" is??

spacejunkiehsv

11-29-2007, 01:10 PM

I'm curious as to what a "VB" is??
Its a Valve Body modification of the automatic transmission. A shop that is most familiar with doing them for our cars is IPT (Import Performance Transmissions). You will see an "IPT VB" acronym on the forum.

I don't know the details of what they do, but they modify the internal mechanicals of your transmission to make it shift differently. As far as I know, nobody has taken the time to crack the Transmission Control Unit (TCU) for these cars. I know that with HP Tuners software, you could tune automatic LS1 cars' shift points through the ECU, nice and easy.

Just do a search for "valve body" and you will find all sorts of info.

Question:

Would you not get the same performance (not longevity) out of your 5EAT if you added a Pitch Mount with a tranny cooler and a Tranny Insert Mount from Rallitek? Versus a VB upgrade?

This VB upgrade is confusing me!
not even close.

the valve body and solenoids are part of your transmission.

Search is your friend. ;)

mikeyan

01-11-2008, 02:04 AM

mounts reduce overall shifting of the entire transmission housing and motor...

VB decreases shift time/delay due to increased line pressure/stronger springs, etc. a VB upgrade can definately extend the life of an auto. The less time slipping(and generating heat) and more time locked up extends the life of the fluid and clutch paks.

Mike
