Took my car to a Dyno Dynamics dyno yesterday. At 8psi it made 238.8hp/196tq and at 12 psi it made 273.4hp/230tq. Those are corrected numbers. Boost kept falling off after 5500rpms and at 12psi it was running a little lean. I was looking to make 300whp but I'm still happy with the results...I know it can make more power with a better tune,different exhaust, and different boost controller.

Mods:
Large streetported S4 JDM engine
Fidanza Aluminum Flywheel
Exedy Clutch
RTek7 1.8 ECU
Turbo XS HPDS boost controller
4 x GReddy 720cc injectors
BNR stage 1 turbo
Custom K&N filter with 3" TID
Custom FMIC
BDC throttle body
Racing Beat 3" downpipe
Stock catalytic converter
Apex'i N1 Duals

 

Link to 12psi run: http://www.youtube.com/watch?v=YwP4MngQyjc

This run was in 4th gear from about 45mph-140mph.

Also, on the graphs the red is the 8psi run and the purple is the 12psi run.

And a FYI to anyone with a RE-Amemiya diffuser: you will have to take the diffuser off in order to strap the car down to the dyno.

 

Those are pretty good numbers on that turbo!

Thanks. BTW I got my BDC throttle body from someone else on the forum but I love it! The porting, polishing, and knife edging on it is amazing!

 

NICE!!!!

Im looking to make a little more than those numbers but with stock ports and a BNR4.

Looking more possible. thanx

 

That's a sweet sounding car you have there. I wished I still had the N1 duals.

 

ditch that stock cat and you should be at 300whp, but you will need more injector though

 

yeah i would ditch the cat too. If you can get away with it. If not move to florida, no emissions here=D

 

I know the stock cat is limiting the power but I had a couple problems when I was running a 3" test pipe. First I kept getting loud exhaust tickets,cops are real dicks around here, and they didn't like 2-3 foot flames=) And second, running just off the wastegate, the boost would spike to 14-15psi. When I run the stock cat, it runs at 8psi and falls off to 5psi. I'm going to be ditching my manual boost controller and probably get a GReddy Profec. I also plan to get the RTek 2.1 and maybe 1000cc injectors. I'm also contemplating getting rid of the Apex'i duals and going with the GT-Spec but I love the look and sound of the duals.

 

Those are really good numbers for the upgrades you have! With 270?rwhp, you can really hurt some feelings on the street, and make some good respectable passes at the track...........Way to Go!! Keep us posted on any additional numbers.

 

that is one big wing on that thing. but nice car. hope you get it straightened out, you got a very similar set up to what im going to be running here shortly, i went ahead and bought 1000cc rc engineerings for secondaries though, and all my emissions are removed, and i believe my turbo is a little bigger.

 

nice car! Is that the re wing too? Got any pics with the diffuser on?

Ya dude that sux that you gotta use your stock cat, ya change that turbo and put a resonated test pipe in there!!!!!

 

Those are great numbers considering you don't even have a fuel controller for the 720ccx4s. The RTEK 1.Xs are awesome.

 

The wing is from Garage BB. It took about 2 months to get from RHDJapan. I don't have any pics with the diffuser on yet...probably won't have any good ones until the spring.

In the spring I'm planning on either getting a BNR stage 3 or 4, bigger injectors, and RTek 2.1 or buying a S14 and putting in a RB25....decisions...

 

this is not badd man.. pretty good.. great numbers man

 

My Future setup is along those same specs,So Now I don't have to "estimate" my HP potential..
Those are not Numbers to be ashamed of..very Nice..Congrats!
