Just thought I might share my power numbers from my new build...

Here is the setup:
Stock sleeved GSR 81.5mm
JE 8.8:1 comp pistons
Eagle H-beam rods
ACL race bearings
ARP head studs
ITR valve springs
GSR cams
Stock head
Ramhorn Mani
Precision SC6152E
3" turbo back
Edelbrock Victor X
PP 68mm TB
Tial 38mm WG
Greddy knock off BOV

Made 420 whp and 270 tq at 20 psi

Here are a few pics of the car:








Edit: Just realized this probably would have been better placed in the forced induction section but I will be racing this soon so what the hell... I'll just add 1/4 mile times as an update later

 

looks good! Was this on pump gas?

 

Nice numbers/clean car.

 

x2

 

Something might be a little off. I have a similar setup with just a 30r and it made the same amount of power as yours, but at 15 pounds. Either way, good job man.

 

Yes that's what I was thinking. We made 400whp at 14psi on a damaged compressor wheel SC6152E. Well it's all about what it was tune for. Could also be the cams holding it back. Good build guy!

 

Agreed...

 

This was on 92 octane pump gas!
To those of you above that stated you made the same power at lower boost on the 6152E...
What fuel were you running?
What was your head setup? P&P? Valvetrain? Cams?
If you had upgraded valve train, what RPM did you run it up to?

I made this power at 8500 rpm on stock head other than ITR valve springs

I am curious what the difference may be between our setups so please chime in...

To all others thank you for the compliments and such

Here is the dyno graph

 

Hey this is Tony right? I met you at IFO wichita. I was with Matt. I am pretty sure this is your old turbo... Thought you might be interested to know that lol

 

We used crower turbo cams in our setup. And if I could remember it was KMS engineering valvetrain, unported head, revved to 8000, 93pump, 1000ft elevation in Germany. This was a few years ago. I would say change the cams for some higher lifting cams will make a BIG difference.

 

Yeah I will probably buy valvetrain first on the stock GSR cams and run it out to 9500 or 10k cuz the damn thing is still making power up top! It wants to be revved even deeper haha! Some cams would definitely help make power but so would some E85

 

I would say if it's a street car, no need to revv that high. Just get a cam that's going to come on strong at 4500rpm. Stock GSR or B16 cams just don't cut it. All the revving is unnecessary in my opinion. Im talking from experience. E85 will definitely make power if tune properly.

 

hey man cams arent needed at all, but some e85 will do the trick for sure

my little black ef you have probly seen at MKC was 410@19psi on pump gas then made the switch to e85 chad made them numbers in my sig for me as well he can for you as well

 

oops i took it out the sig my bad man

494 on a stock block with e85

what injectors are you rocking

 

Unfortunately the injectors are what stopped me from going e85 this season. They are 650cc precision injectors and I need 1000cc min to push good power with the increased volume needed for e85...

What injectors are you on? 1600's?

 

1000's

 

Clean car/set up

 

I got an extra set of 1000's I'd let go for cheap. ;-)

 

I don't understand. Explain to us why it wouldn't benefit from putting a good set of cams in?

luk4rmkc: can you tell us your entire fuel setup?

 

didnt say he wouldnt benefit what i said is its not needed all he needs is a bigger set of injecotrs, and he will be good on e85

do you think he needs the bigger after market cams just to make good power?

 

ooooo Hahah. Yea it was a friend of mines turbo! Thats awesome see you in sept again!

 

Nice

 

clean car and nice power!

 

I have gsr cams in my car an i make 723 hp at 26 psi . Cams are not that big of deal an i rev my car to 10 thousand rpm .

 

exactly some think you need aftermarket cams

op needs fuel (injectors, and better fuel)
