Got Dyno Results today

[funcrusher]

I decided to add a supercharger to my Mustang earlier this summer, which I thought would be a week or less job. Shortly after beginning, I found out this was not so because three and one half months later I picked up my car from it's final dyno tune at Kauffman motorsports. The journey was hard but it was all worth it when I watched the drag radials spin on the dyno to the tune of 404 RWHP and 392 lbs. of torque. I have a 96 GT with a vortech S-trim pumping 12lbs. of boost, I did the PI head and intake swap I have a 75mm TB, BBK long tubes, and matching X-Pipe w/o Cats, new flowmasters 30lb. fuel injectors, BBK adjustable fuel pressure regulator, and BBK inline Fuel Pump. The drive train is mostly stock I have a heavy duty clutch and 4.10 gears all feeding to the previously mentioned BFGoodrich Comp TA Drag Radials. With this combo I hope to be running mid 11's I feel confident I can break into the 11's but only time will tell. I am at my fiancee's house but when I get I am going to scan my dyno sheet and post it later on this thread. Good Luck to the rest of you and don't give up!

very, very nice man

I hope you have some forged internals in that engine. Otherwise you are taking a very big chance on blowing it with that much boost if you drive it hard. If you get a good launch and drive it hard you should see some 11's. Good luck.

were did you order you heads, i have a 97 vert and want to do a pi head swap, but dont know were to start??

 

[slvrbullIT]

nice, i wish i had a supercharger with the head swap, everyone always says that the higher compression cant handle it. let us know how it holds up.

 

[hotforstangs]

Nice #'s, but you will need forged internals and lower compression, I did headswap and s trim on a stock lower end and did a conservative tune,, high compression of about 10.5 to one and 12 psi of boost, I even had methanol injection, and bye bye went piston #1 ringland

 

[RedGTvert]

What the heck is holding you back? Other then the injectors being too small, that setup should be producing a fair amount more hp/tq then it is.

Is this a stock bottom end? What did Kauffman set your timing at?

I would still like to hear why you are only running 30# injectors.

 

[DiabloRojoStang]

From what I've heard PI heads on a 96-98 GT + Supercharger=BOOM
I hope yours hold up. Good luck and keep us posted

 

[BLK_ROUSH]

Congrats on the install and new found power. Would like to see how long it lasts.
I've seen and heard the same PI swap + S/C = BOOM!!! stuff. But, there are stories of guys going fine too so ... either way. Congrats.

How come it took so long?

 

[stang9gt]

I'm am thinking of doing that to my PI swapped 96...I say a few guys running lower boost, making 417 rwhp and having no probs...

My horsepower is only 404 because my Air/fuel Ratio is 12.5 to 1 which is what is going to make the motor reliable. I had some concerns myself buy Dave from Kauffmans told me it would be fine as long as I don't dog it all the time and just drive sensibly. I am not too worried about because in two or three months I am putting a fully forged 302 stroker shortblock in it. I got my heads and intake from steeda because they come fully assembled with cams and everything and it took so long because I bought the damn Supercharger from Muscle Motors Performance which is the biggest mistake anyone can make, they sent me a Cobra charger instead of a GT charger so it didn't make any boost and I had to send it back to Vortech to have it rebuilt, and they do this on purpose because the SC charger is a little sheaper than the S trim. SO please if you guys are thinking of a vortech supercharger take it from and save yourselves the trouble. Just say NO to Musclemotors Performance.

how is the drivability of the car after the tune..im going to be heading to kauffmans in a few weeks to get tuned...what software did he use to tune it? thanks

Actually, I think that's a little lean. From what my tuner told me(Mike Murillo who is one of the best in the business), the ideal A/F ratio is 11.5-11.9. Are you running race gas or just premium?

I also agree that your injectors need to need upgraded too. Get yourself some 42's......

Thats what I was thinking. Seemed a little on the lean side.

OT - Firemanz
You ever get a chance to go to Murillos shop and get a few pics of my car?
