moviemadness Posted March 8, 2006 Share Posted March 8, 2006 I've searched and read over 20 posts about this intake, yet there were no known solutions or definite issues with the product. All the posts just seemed to die out with no conclusion. Does anyone have FACTS about this intake or PROVEN problems with it? I know all the audible issues, but are there any proven facts that it will mess up my engine or cause potential damage? I might have acted a lil too soon, cuz I should be receiving it in the mail tomorrow. btw - stock engine as of now. plans: AP stg. 1 Link to comment Share on other sites More sharing options...

PhilT Posted March 8, 2006 Share Posted March 8, 2006 The logs taken by myself and Mccorry, and possibly others, prove, without a shadow of a doubt, that aftermarket intakes cause your AFR to run leaner than normal. This has been proven to cause higher exhaust temps and the ECU pulling timing to prevent knock. So although the noise may make you feel like you're faster, it actually is probably robbing power. Whether it will actually cause long term damage is not known yet, but I didn't want to risk that with a C$35,000 car, maybe some people do ?

rony Posted March 8, 2006 Share Posted March 8, 2006 This wasn't the big map intake, it was the standard one? Right? Is the MAP housing a different size or configuration so that it's causing an invalid reading on the MAP sensor? Or is it just flowing more air?

PhilT Posted March 8, 2006 Share Posted March 8, 2006 It's the turbulence that misleads the MAF sensor into reading less than is actually passing. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
rony Posted March 8, 2006 Share Posted March 8, 2006 Um... Good to know... Guess I will be putting it while the car is sitting on the Dyno for it's next protune. My Car vBGarage Link to comment Share on other sites More sharing options...
malfeas99 Posted March 8, 2006 Share Posted March 8, 2006 Yep, I can vouch for this... untuned it can give problems. I had a 'stage 1 equivalent' ecutek tune (helix uppipe), and went to my shop for the intake. I put it on, and drove the car to mcdonald's while waiting for my turn on the dyno. I got detonation within 100 feet of leaving the shop, and the advance multiplier went to .5. After a tune, I got significant power gains, especially hp on the top end.

The MAP sensor isn't affected by the intake. Link to comment Share on other sites More sharing options...

SWP-LegacyGT Posted March 9, 2006 Share Posted March 9, 2006 what do you mean by a tuned car? how extensively tuned? Good questions sir and I'm glad to respond. Usually a Stage 1 ECU reflash can handle the CAI or the Short Ram. Usually though it's best to flash the car ECU, get an Up or Down pipe for your exhaust and THEN think about getting a CAI. Now, the ideal situtation would be this: Stage 2 ECU Flash Up Pipe Down Pipe with high flow cat Full exhaust system from HFC back Perrin Short Ram Intake or alike. That's the ideal.

Thrasher Posted March 9, 2006 Share Posted March 9, 2006 Patiently waiting for the Cobb intake... Much less turbulence, much more accurate maf readings, according to Christian B at Cobb. Shouldn't be more than another few months or years until it's out. Link to comment Share on other sites More sharing options...
TSiWRX Posted March 9, 2006 Share Posted March 9, 2006 Indeed, the current consensus is that non-laminar flow seems to be the problem. My LGT (currently UP, shorty DP) was custom-tuned with the Perrin in-place, and it seems to fare well with a comparable vehicle using the K&N Typhoon. Brother GTsleeper's '05 5EAT and my '05 5MT share the same wHP curve, but it is worth noting that he has about 70 more wTQ, on the same dyno, than me, at a significantly earlier point in the powerband - not sure if this is due to the way dyno reacts to the 5EAT, or if it is capable to be traced down to the intake, as I have not yet had a chance to "swap vehicles" with my good brother for a back-to-back test-drive. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...

moviemadness Posted March 9, 2006 Author Share Posted March 9, 2006 I think I read somewhere in this forum that says that the perrin intake will be ok if everthing in the engine is stock. Is this true? how about if later on I get the Cobb AP stg. 1, then should I remove the intake? Link to comment Share on other sites More sharing options...
