Just doesn't add up

Dynod the truck today. Only hit 402hp. How is this possible with my mods. Every post I see with similar mods to mine is 500hp +. Dyno was a mustang 1100. Truck boosted to 43psi

238/200% injectors
38r turbo
Full fuel system holds 65psi
Srp1 holds 3100 psi
Tuned by jonathan at no limit
Studs
Springs
Suncoast tranny

Can some one please tell me wtf the problem is

You are way way overfueled for one.

Do you have a graph?? Were at rpm wise did you start your pull?

Moar...... air.

Too much injector for that turbo.

P.I.S_7.3 · Mar 16, 2013

If its not enough air then how is it every thread with 238s and a 38r hits 500 damn near every time at 450-475

The dyno operator started the pull soon as it hit 3rd with od off

Ran atleast 7-8 times number never changed. Yet my track times say more power than the dyno says

Thought hybrids and the 38r were a good match also.

Most guys only run 100% nozzles with a 38r

Same tune?

P.I.S_7.3 · Mar 16, 2013

Yep same tune. Hot tune from jonathan. Same setup runs 8.1s all day long on the 1/8 track

P.I.S_7.3 · Mar 16, 2013

I had this same setup with 100% nozzles. I can tell you the 200% s added noticeable power increase

238/38r is stretched out at 500+HP...

IMO it's a ~475hp setup

CSIPSD will agree with me as well.

Far too many of y'all throw the "all mighty" 38r with 238's and expect 500+ like nothing.

OP, you def should of put down more than 402hp though. We're you able to fully spool up? What were your gauges reading? Like others have already stated...too much injector;too little turbo

P.I.S_7.3 · Mar 16, 2013

I knew the turbo was small but damn. S467 coming real soon.

smoker00 · Mar 16, 2013

Mite try a different tune just to see if it changes.and maybe a different dyno. Im no expert at all but that seems low.. my 175/100 along time ago did like 4 something at 4700 ft. The good thing is your track times put you over your number by a bit. Track time are what most of US care about any ways.
