Rhitter Posted March 31, 2016 Share Posted March 31, 2016 Does anyone have comparisons of the standard VF52 v the JMP52. Curious if there are any noticeable differences. My OBXT build Link to comment Share on other sites More sharing options...

Rhitter Posted March 31, 2016 Share Posted March 31, 2016 From a reliability standpoint he upgrades the journal bearings. I guess I am more interested in the other things he does, Billet wheels etc. But unsure if anyone had direct comparisons from an OEM cast wheel unit to the upgraded one.

TheMonaLisa Posted April 1, 2016 Share Posted April 1, 2016 Sorry I can't help you more. Never ran the VF52 in stock form. Had JMP intentions from day one so bought a blown up VF52 and sent it directly to him. His billet compressor wheel for the VF52 is a full 11 blade compressor wheel where as his billet compressor wheel for the VF40 is a 7/7 blade. I know tuning alliance has a table over in the tuning section comparing compressor wheels and exhaust wheel sizes of various turbos including the VF52. The VF52 in stock form has a slightly smaller compressor wheel than exhaust wheel. Thus supporting the argument for a larger compressor wheel.

Andy_Mac Posted April 19, 2016 Share Posted April 19, 2016 True, but would have thought atleast one person who's had it done would have at the time of getting it back been interested enough to quickly pull the comp cover off and measure the inducer/exducer numbers. 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...

Smithcraft Posted April 20, 2016 Share Posted April 20, 2016 Does anyone have comparisons of the standard VF52 v the JMP52. Curious if there are any noticeable differences. While I'm not going with the 52(staying with the stock turbo), I'll be driving the 08 to work tomorrow and I can see if I can log stuff with the AccessPort, then I can compare it when I get it back and installed. However, I might put a fancy inlet hose in while the turbo is out so that might skew the post JmP numbers though...

firerescue9 Posted April 20, 2016 Share Posted April 20, 2016 Subbed, I thought the stock vf52 has he ability to put down like 320 to the wheels? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
shralp Posted April 21, 2016 Share Posted April 21, 2016 All depends on the brand of Dyno your using but you won't get more than about 300 whp on pump gas safely on a heartbreaker Dyno like the Mustang.The 52 just isn't big enough to hope for much more.

firerescue9 Posted April 21, 2016 Share Posted April 21, 2016 Hell I've even seen builds with 1000cc e85 and basic bolt on wrx's with like 330ish whp. Hopefully jmp will jump in here soon, I sent him a pm couple days ago about building me a 52 but no reply just yet Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

cryo Posted April 26, 2016 Share Posted April 26, 2016 What's up with your boost control and afr? Leaks? I remember we tuned this car back in 2014 but not sure if the dyno was right after or quite a bit afterward. There is no wideband data during the etune and the intake was stock so it could be a leak that generated after the process. The boost control is actually smoother than it appears on the sheet but had a little spike during the dyno obvioulsy. This didn't show up in the logs on the "road". Sometimes the filtering on mustangs software *older and newer so it must be in the settings* causes it to be jagged like the hp and tq curves as well. Hope this helps!
