About what HP will I make
So here's my build in progress plan. I need help figuring out how much HP I could make with it.
S5 TII block S5 NA rotors Mild street port VMIC Apex'i filter into custom TID Apex'i dual N1 (so far, but hoping to get a single exhaust soon) Corksport downpipe + test pipe meth/water injection into the turbo + the intake mani 720 secondaries Rtek or power FC to tune Stock turbo w ported WG I think that's about it. I'm trying to figure out what size injectors I need for the water/meth based on how much HP I can make. Give me a realistic high number so that I can tune it safely for a conservative amount of HP. If I need different fuel injectors then I can get those as well. |
250ish?
|
Drop the meth/water injection... Add BNR stage 2, 720cc primaries, and 1,000cc secondaries. (A'PEXi Power FC)

I agree, drop the meth injection, it's just an extra failure point.
Also, you're gonna need bigger injectors... I run 1000/1000, but you could probly get away with 720/1000 Then grab yourself a BNR stage 4 turbo and you can make 300-340 hp easily. I'm making 280hp@15psi (that would be about 300 on a dynoJet) on BNR stage 4, full RB exhaust, stock port s4 TII motor, and stock TMIC. The TMIC is my main limitation as it makes my intake temps excessively high past 15psi, so with a VMIC you will be able to crank up the boost. if you're dead set on the stock turbo for some reason, you can't really make more than 250hp with it. Also, you don't need to run a V-mount set up for the stock turbo, its kind of a waste... |
water/meth injection basically raises the efficiency of the turbo, so on the stock turbo, you can go as high as 18psi or more if you are careful.
With what you listed it should do more then 250rwhp. To get out any more HP, your injectors are limiting you, at 550/720, its limited at a safe range to about 250-260rwhp. A 720/720 setup will give some playing room to atleast 330rwhp. |
I was thinking of a BNR. Probably wouldn't go any higher than a stage 3. Most likely stage 2.
I'm honestly a bit surprised hat the numbers are so low. I should also add this is a fresh build. Lapped irons and refurb housings. I'm hoping for real good compression numbers. |
The numbers only seem low until you drive it. I was like "280 hp? lame, I was shooting for 320...". Then I drove the car... it's pretty damn fast.
If I had to do it again, I probably would have gotten a stage 3 as well. you'll get better response times, but again, the car is not gonna be slow with either. |
Mostly going to be a fun track car. Possibly drive it on the street for rare occasions as well, but mostly track.
