Arrite I did the hotcam kit a Holley 52 mm throttle body. First time I dynoed the car was at 257 rwhp. Now after I got the thing dyno tuned its only at 285? Whats the deal with people claiming that they get "330 hps" off the hotcam kit. They should be drop kicked in the face. I don't understand what is goin. I am pretty damn dissapointed. Anybody have any input? Or is this just normal. Or was it the dyno? I tested at speedinc. Thanks guys. Please Gimme Some FeedBack.

 

did you tune the car. The computer can do only so much.... But since you were at the dyno you should have A/F ratio readings? Are you using the stock heads? Bigger injectors?

 

I dynoed 289 at the wheels with bolt-ons.
Did you use a Mustang Dyno?

 

I am using stock injectors and heads. But i have a 255fuel pump put in. I forgot the brand, it began with an M. But the dyno is used for stangs F-bods, vettes. But I dunno am I on crack or somthing? Or are those numbers right?

 

i hope you have some long tube headers and a nice catback exhaust But i am guessing u dont....so u might want to get on that

 

Definately get a wide ban and see where your A/F
ratio is at. Check all the obvious things twice. And
more info is needed regarding exactly how the car
sounded when it was on the dyno. Scan the chart
and put it up.

Are you running cats?

Have you checked exhaust back pressure?

 

u dont look like u have exhaust from ur sig

if u dont what the hell did u expect with the stock exhaust including the manifolds?

catback/longtubes or midlegnths will easily get u around 320-330

if u do have an exhaust u better find out whats wrong

 

I have the slp exhaust that came on the cars in 97. All stainless, with the stainless pipes commin out the drivers side. Headers really make that much of a diff??!

 

Yeah, you wont be making any kind of power without headers. Stock manifolds are good for boat anchors.

 

You might scare off the fish with those thing.

Also, you might need better springs and/or a valve job. I lost a bunch of HP from week springs which ended up screwing up my valves.

 

get some 1.6 RR and some ceramic coated hooker long tubes on that thing and watch the number jump

 

If he did the kit, it should already have 1.6rr's in it. Definitely get some headers on that bitch!

 

Naw I have the 1.6RR's and the LT4 springs. ..Boat anchors though....perhaps a valid use

 

My bad on the kit situation

 

Not a problem bro.
