got the mustang dyno'd
 

Well I'm disapointed but i think its because i dont understand the mechanics of it all, but im learning.

i dyno'd at 198.8 HP and 237.2 TQ
with the mods:
typhoon ported intake, 70mm tb and egr, stock air meter, stock fuel system, b303 cam, stock heads, sotck rockers,stock mechanical fan,upgrades valve springs stock ignition except for mallory ignition coil, plugs gapped to 45 timing set at 12*

A/f was pretty good it was about 11.9-1 almost all the way through the RPM range. it was only rich from 1700RPM's to 2200RPM's at a 13.5-1

my TQ peaked at 4200RPM's ish and HP peaked at about 4500RPM's but just barely went down from 4500 to 5300RPM's

it looks like it just lost its breath from 4500 on. they guy that dyno'd it said its because of the larger intake my air is losing its velocity and i could really use some heads(duh..) and a new air meter(so its not restricted and then the air loses all its speed going into a big open space.)to bump those numbers up the best.

the place i got it dyno'd at, they specialize in mustangs...the family owns like 15 fox bodies that are all track cars, full restored, originals, road course cars ect., and he said he was fairly impressed by the numbers he said, he thought i was only going to hit 170ish with my mods. i thought i did crappy with the 198....



tell me what you guys think.

**EDIT**
he also said my cam and intake dont match so its kind of hindering some performace.

hmmm that seems really really low, at least to me..

RE: got the mustang dyno'd
 

my thoughts exactly...

RE: got the mustang dyno'd
 

get a 70mm SN-95 maf.. and also try pulling some fuel out. 11:1 is WAY rich for an n/a motor.

you want it to be around 13:1 for your entire pull

RE: got the mustang dyno'd
 

well i said 11.9, so basically 12 the entire pull. is that still too much?

RE: got the mustang dyno'd
 

ok i just called around to some salvage yards, I'm gonna go pick up a 95 mustang mass air sensor for 40 bucks....is it just plug it in and go or do i need it to be tuned when i put it on? do i need to do any wiring?

RE: got the mustang dyno'd
 

wow 198 something is wrong. with o/r h pipe TB and CAI i got 210rwhp...

RE: got the mustang dyno'd
 

i called a guy at C&L just to see if he could shed some light on the MAF sensor. he actually said its common on our cars to get low numbers with the small mass air with large t/b. he said because im going from a tiny inlet to a huge t/b in comparison 55 to 70mm. he says this causes a large amount of turbulance and loss of air velocity. he said he honestly wouldnt be surprised if i switched it out to a 73mm MAF and adjustable fuel pressure regulator to have it up around the 220-230 range just because my my car is not being allowed to run at its full potential. I faxed him my flow sheets and he called me back with that info. he actually sent me a before and after dyno sheet with a 87fox with the same symptoms as mine. so i think i might vest into those two things, and roller rockers when i get a chance. lol.

RE: got the mustang dyno'd
 

B cam is a little old school and he's right on the heads...also add some roller rockers with head swap but 11.9 would be richer than 13.5........13.5 would be more of an ideal on a N/A car;)

RE: got the mustang dyno'd
 

also if you look at my dyno sheet you can see how it loses its breath around 4k....he also said thats what makes him suspect its the mass air, the higher RPM's with the smaller mass air is making it so i cannot shove enough air into the intake....makes sense to me. the before and after he sent me almost look exactly the same as mine before, and the after you can see how it pull hard entirely to5200RPM's. the only different in teh 87fox is, he had a cobra intake and TFS1 cam....otherwise pretty much the same as mine.
