I'm trying to see what I can do to get more power out of my setup.

I'm thinking about getting a gt28rs .82 a/r for streetability or or a gt3037r .63a/r for more power.
Right now I got a precision sc50 with .63 a/r



you can clearly see my dyno stops climbing significantly past the hp/tq crossover, and Im thinking it mayhave to do with my head, and IM setup.

I've been toying with getting a better flowing head, and possibly a large IM and TB setup.

any thoughts?

 

need your whole setup and also what boost level

 

D16Y8 block/head

CP Forged 9:1 pistons .020 over, Eagle Rods
Crower Valvesprings, Crower Titanium Retainers, Zex Stage 2 cam, AEM Cam Gear
d16y8 Ported Intake Manifold and Throttle Body
”Silly Sohc” Ram Horn Manifold, Precision SC 50 turbo with .63 a/r

Stainless Steel 3 inch Downpipe, Kteller.com 3 Inch Catback, Moroso Spiralflow and Dynomax Race Resonators

Neptune, RC Engineering 650cc injectors, Walboro 255 LPH Fuel Pump

 

id personally be pretty happy with those number on a dseries

but a gt28rs would be great for the street. a tad laggy on a dseries but prolly no worse than the sc50. and a lot easier to bolt up then pulling the whole head for porting or replacement

i've heard the gt28rs may max out at around 300whp so i'm not sure if this is the route i want to take.

I may even invest in the BB CHRAs from precision

 

i always understood the gt28r to max out at 300 and the rs 350ish

plus it will flow more topend so even if you dont make too much more power you certainly wont be falling off like you are now

 

SC50 is good for 450hp, no?

How much boost are you running?

I have the same turbo on a similar setup, only I have an Edelbrock IM/TB. Hopefully I'll have numbers soon.

 

stick it out w/ the turbo you have for now and get some headwork done.......

great idea. it'll free up some power.

Yes i think that would do it IMO. I think my power flattens out after the xover because its now flowing fast enough to consume all the air...

 

it gets good flow up til the point where it crosses to VTEC and then it pretty much poops out......headwork would free about 30whp or more i'd think........

 

i'd send the head to headworks as they did on the f-r pinks car.

yeah but that head would cost $1700 to replicate
