am i losing hp???

franky · September 2nd, 2007, 09:06 PM

i own a bullitt with 91 on the clock these r the mods

k@n drop in
160 thermo
long tube headers
slp catback, with straight pipes no cats
x pipe
recenater mufflers
(2 1/2 tubing)
lower control arms
panhard bar
4.10's
predetor with custom tuning
deep dish bullitts
short shifter
100 shot zex wet
i replaced the iac, cleaned the filter and maf. sprayed some stuff like sea foam in the system to clean everything reguler motorcraft recomended oil and im pushing 263 naw where a lil while ago i was pushing 270(n/a) i lost 4 hp and still with all of this. shouldnt i get more power? my numbers on spray r 330rwhp is this right or is something wrong? i know the dyno reads the car off cuz of the gears. how does that work, and i did this in 315 sumitomos if that helps.

welcome to the forums.

sounds like you need a dyno tune instead of a canned tune.

00SlvrStang · September 2nd, 2007, 09:09 PM

your numbers will vary based on weather conditions. i wouldn't think too much of just a few horsepower difference.

franky · September 2nd, 2007, 09:12 PM

hey thanx all. lol first post. i live in vegas. i guess your right but wit the mods is this good numbers

franky · September 2nd, 2007, 09:13 PM

what about the gear thing whats the math on that

he said custom tune in his list of mods

weems · September 2nd, 2007, 09:15 PM

i would say thats about right with the mods listed

00SlvrStang · September 2nd, 2007, 09:16 PM

the numbers sound pretty good but i think you should be getting more out of your nitrous. you're only getting 60hp out of the 100 shot, you should be getting close to a 100 with a good tune.

HMUSN · September 2nd, 2007, 09:18 PM

a custom tune is a fancy word for canned tune

00SlvrStang · September 2nd, 2007, 09:22 PM

depends on who you ask

00SlvrStang · September 2nd, 2007, 09:22 PM

he's obviously had it on a dyno so why is it hard to believe that they didn't tune while it was on there

franky · September 2nd, 2007, 09:23 PM

yea well i also forgot to mention the botle opener and purge kit.. it was done by the guys at the speedway. i seen a bullitt there all the time and figured they reg my car. i remember that they said that i should only tap the purge like 2 times to let the air out. i went to the track and they said to do it till u c white smoke. this makes more sence 2 me is that true

HMUSN · September 2nd, 2007, 09:24 PM

i just think with a dyno tune you should be able too pull out a bit more than that is all

franky · September 2nd, 2007, 09:27 PM

the guys prob gave me a safe tune thats all

2000stangGT · September 2nd, 2007, 09:38 PM

seems a little low to me

id do an n/a dyno to see where you at there. should be around 260 rwhp i would think

elevation and weather make a big difference too

wut is your elevation?

franky · September 2nd, 2007, 09:51 PM

elevation. heck if i know. i been trying to find out and no one knows. this club from az came for the race track and they were pulling 13 and 14's and there cobras as we all know pull 12's. they said we have bad elevation air density is good i would think

weems · September 2nd, 2007, 09:55 PM

what kind of dyno were you on each time?

White99stang · September 2nd, 2007, 10:28 PM

dyno's can read different every time you go, at the same dyno i made 296rwhp and went back the following month and made 283rwhp, You are not losing hp, just going to different every time depending on weather, how hot the car is, the load they put on the car. The real difference is in the way it drives and how fast you go at the track.

MustangMatt96GT · September 2nd, 2007, 10:30 PM

Dynos suck!!
Quarter Mile Times are where its at!

Fluffy The Rhino · September 3rd, 2007, 01:24 AM

Vegas = Extremely high temps = not so happy engine

I was stationed out there and the hotter it got, the more power I lost. Same thing out here, plus I have 4,000% humidity. Effing Alabama. Anyway, heat will make your car very not happy. Definitely robs some of it's power.

I used to love driving up around Red Rock/Blue Diamond. The desert is gorgeous out there.
