1-3-2-4 Posted October 31, 2017 Share Posted October 31, 2017 I'm curious maybe it's here or not but at stock PSI levels about what does a VF52 put down? And about what PSI range is the VF52 good for? Can you do 300WHp at 18 PSI? Link to comment Share on other sites More sharing options...
shralp Posted October 31, 2017 Share Posted October 31, 2017 18.5 lbs netted me the numbers in my signature. This is with 740 injectors and Walbro fuel pump however. 91oct. Gas on a Mustang Dyno at Cobb Surgeline, Portland, OR Link to comment Share on other sites More sharing options...
gkinslow Posted October 31, 2017 Share Posted October 31, 2017 I hit identical whp (290) and slightly less wtq (319) with stock injectors @ 18.27psi on 93oct. on DynoJet. Link to comment Share on other sites More sharing options...
xtea Posted October 31, 2017 Share Posted October 31, 2017 E85, 21psi and fuel mods will get you there on a vf52. With out fuel upgrades you just cant maintain boost high enough to squeeze out the horses. Link to comment Share on other sites More sharing options...

henhead Posted November 1, 2017 Share Posted November 1, 2017 FWIW I've got a BNR EVOIII 16g and hit 300whp and 310wtq at 17psi on a mustang dyno a while back. That was with a bigger pump and 850cc side feeds. Link to comment Share on other sites More sharing options...
LegacyKid5 Posted November 1, 2017 Share Posted November 1, 2017 18.5lbs on a VF52 and that resulted in 309HP/333TQ to the wheels tuned by Cobb Surgeline on a Mustang Dyno. Link to comment Share on other sites More sharing options...
1-3-2-4 Posted November 2, 2017 Author Share Posted November 2, 2017 Is the VF52 and 16G about the same in output? Link to comment Share on other sites More sharing options...
xtea Posted November 2, 2017 Share Posted November 2, 2017 100 rpms difference. Vf52 is usually torqueier but with 10-15 fewer hp. Link to comment Share on other sites More sharing options...

subie-roo Posted November 2, 2017 Share Posted November 2, 2017 Just over 300 at 18psi on E85, significantly lower on 91 (255 I think) on a "heartbreaker" dyno with a 5EAT and plenty of supporting mods. Link to comment Share on other sites More sharing options...

subie-roo Posted November 2, 2017 Share Posted November 2, 2017 So what you're saying is that mine is gonna be a lot of fun with a manual? Indeed it will be! The VF52 hits early and maintains through redline. With the E85 I can run up to 22psi (which puts me around 318hp and 385tq) but I keep it at 18 for daily driving.

MTBwrench Posted November 2, 2017 Share Posted November 2, 2017 I never see anyone speak on the JmP 11 blade VF52 numbers. I guess i'll find out once I complete my build. Look at my signature 266whp @17.5psi on 93oct., holds it till pretty much redline with low-mid 10.x AFR's. Not on stock fueling though. DW65c with ID1000's. I would say spool is about the same for me, we intentionally tuned to spool a smidge later in an effort to save the trans(which crapped the bed anyways). The trademark characteristic of JMP turbos, to me, has always been how responsive they are and wide the powerband is. This VF52 when combined with proper fueling, seems like it'll hold horsepower as high up in the rev range as you want.

Max Capacity Posted November 2, 2017 Share Posted November 2, 2017 Have to agree, even with stock fueling ,it pulls pretty good up top. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

1-3-2-4 Posted November 2, 2017 Author Share Posted November 2, 2017 The thing is it seems he's to break 300 without running e85 I have a dw300 pump but I can almost say this vf52 is going to be very short lived in my car I'm trying to get between 310-330whp on 93 I think the 20g is the only way to get to that level.. I would of went with that from the start but I had to get the car up and running so I just used the vf52 for now Link to comment Share on other sites More sharing options...
MTBwrench Posted November 2, 2017 Share Posted November 2, 2017 IMO, all things considered, you're getting into the upper end of what a VF52 is capable of if you're looking to be in the low to mid 300's. Especially on pump gas. You'd be safer off with something a little more efficient up there, in the long run. Other things to consider: you have head studs right? you'll run the risk of stretching stock head studs at 22+psi. won't be an immediate issue, but a long term one.

Are you referring to the vf52 or the 20G my understanding is I can get my target with the 20G at a lower PSI then trying to push a VF52 20+ psi. And i'm using the stock head studs Link to comment Share on other sites More sharing options...

And i'm using the stock head studs What I'm saying is what you're thinking. For those numbers, a larger turbo may be more efficient. That being said, and I'm sure some will disagree with me, I'm not sure I would've rebuilt with stock head studs if I was looking to be in the 300+hp range. That's more of a precautionary thought though. MTBwrench's Stage 3 5EAT #racewagon 266awhp/255awtq @17.5psi, Tuned By Graham of Boosted Performance Everyone knows what I taste like.

Max Capacity Posted November 2, 2017 Share Posted November 2, 2017 Talk with Mike at www.tuningalliance.com about which turbo he recommends, I'm sure it won't be a turbo with a "g" in it. Better stuff out there, he'll give you the best tune too. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
