ok kinda a weird question but im just a little confused i am running a redtop sr with hx35, 850 injectors, and hks 264 cams along with all the proper suporting stuff and a power fc d-jetro and talking to my tunner he said i should only make between 250 and 300 hp. that just seems a bit low to me i have herd people making alot more with similar setup as mine if not not less. i made 310 on my rb20 with stock injectors and turbo and chipped ecu!!! just woundering if he is yanking my chain or what. they are very respectable tunner so i wouldnt think so.. i was really hoping for around 450 if ya know what i can change to acheive this let me know!

burgessn · 03-15-2012, 04:04 PM

yup already did that and got air on all 4 cylinders!!

i got 300hp with 16psi, 850cc, stock longblock e85 and a canned rom tune.
id expect more from your set up being fully built running more boost.

burgessn · 03-15-2012, 07:36 PM

Ya thats what i thot!! thanks for the replay were does everybody go to get tunned just curios?

Go to koji at Driftspeed and never look back. I waisted so much money on bad tunes before I found him. And that number sounds really low to me. On koji's dyno pack (known to read low) we hit 275 at the wheels with a s15 turbo, 550cc injectors, and a z32 mafs. It actually read out 292whp on gdimentions dyno jet.

I'd be pissed if I spent all that on those parts and only hit 300
