kenne bell dyno

jj89fox · Apr 10, 2010

I just run my car on the dyno for the first time with my new setup its a 89 fox with 56,000 miles it was all stock except a bbk cold air and a mass air now i have a aftercooled 2.2 kenne bell mac headers, 2 1/2" exhaust ,70mm throttle body and 355 gears what a difference i am going to up the boost to 12 psi from 8.5 psi

I love the torque band on your motor, thats exactly what Im looking for.

ps- your motor confuses me, where do the other 2 intakes lead too? a front mount intercooler?

NIKwoaC · Apr 10, 2010

Is your A/F really running that lean?

S&B · Apr 10, 2010

is that your setup ?

there was another guy with a sweet custom aftercooled setup on a red Fox.

Love the blower whish they could make an aftercooled Mamoth setup for the fox (5.0)i wouuld buy it in a min.

Nice numbers..A/F looks way LEAN!!!!! I was going to go with a KB then i said for the money turbo would be better for my application....Nice numbers tho

jj89fox · Apr 11, 2010

Yes this is my setup I got the idea to try it from a post on this site my AF was lean I am glad it made it through the dyno pull I have to go back for the tune one of my silicone couplers was collapsing at idle

Holy ****. Can't believe the tuner even completed the run seeing a/f #s like that in a boosted car. I would have ripped him out of my car by the throat.

MY 85 GT · Apr 11, 2010

I might be wrong here but once you get that A/F down wont you loose HP...i know when you go richer it takes away some HP...I hope not tho...

jj89fox · Apr 11, 2010

I hope to make a little more HP when i go back for the tune with a smaller pulley my goal it 325 rwhp

KB Boost a pump!
I agree with blackened88lx, my tuner would have stopped the pull @ 3k without a doubt!!!!!!!!!!!!!!!!

I wouldn't even drive that car except back to the shop you had it tuned at and up the tuner's arse.

jj89fox · Apr 11, 2010

I just did one pull to see what hp i would get i did not get it tuned the place that i brought it to is vary good at what they do. They told me it would not be the best idea to run my car up to high but i did it any way and it still runs fine. Would i do it again not after i seeing how lean it was. i am getting it tuned next weak. it just goes to show how important it is to get a good tune

Agreed, only an idiot would stay in it after seeing numbers like that.

No, it'll probably gain horsepower.

14.7 is stoichiometric or theoretically "perfect", though typically a safe tune is richer than that. Yes, sometimes you sacrifice a little power by going with a richer, safer tune. However, anything above stoich is dangerous and could cause engine damage, and also will rob you of power. Looking at his A/F, he was well above 14.7.

i cant believe the car made it through the pull that lean, arent boosted motors supposed to be around 11.5 to 11.9:1 AF?

It will gain power.

Yea, no leaner than that. I've seen much crazier things survive though.

MY 85 GT · Apr 13, 2010

I tend to diagree..I think if he goes to 11.5 or Richer i think he will loose HP maybe pick up some torque were the KB shines...Just my opinion...I can be wrong not the 1st time...LOL..Im sure he will post new numbers when he is done...

Mr. Rustypwnz · Apr 13, 2010

only 300rwhp WITH boost? am i missing something?

Uhh. There isn't really anything to have an opinion on or disagree with. It will pick up power. That's just how it is...

Yes 309 rwhp a stock 5.0 is only 215/225 at the crank its hard to make big big numders with stock e7 heads I hope my pully gets here by thursday so I can get my tune and start to enjoy the car
