Got back from the dyno late last night

[Stylin Cobra]

I went down to Vancouver, WA yesterday to get a custom tune on a dyno for my car. I met up with Chung from Blue Oval Performance and we went to the dyno shop. Anyway, after 2 hours of tuning I ended up with 398.54 HP at the rear wheels (SAE corrected. it was 407 w/o correction) at 6,000 RPM at 6 psi of boost That's about 465-470 at the engine so i'm really happy. I couldn't take it to redline as I was out of fuel at 6,000 rpm (the air/fuel ratio was starting to spike dangerously at 6,000) So it looks like I need a bigger fuel system to go further.

Man what a fun day though I got about 12 pulls in. Nothing like beating your car mercilessly for the sake of power!

Thanks again Chung I'll come back when I get a bigger fuel system

edit - oh yeah the combo. 97 cobra, novi 1000 (stock pulley), a/a intercooler, 3" universal maf, 42# injectors, bassani catted x, magnaflow catback, msd dis-4

Nice numbers! What were your baseline numbers?
Good job on the tuning Chung!

 

[BoostedmaxPSI]

Not bad for just 6psi! Any plans on some race gas and 15psi? The bottom end of your motor should be good for 600HP.

Thanks for the opportunity.

Nice car by the way.!!

heh,

thanks. I have been doing some research and maybe it's just my fuel rails are too small at this point as they are only good to about 450hp. so i might just need bigger lines as teh fuel pressure didn't drop at all, just the a/f ratio went haywire time for some steeda extruded 1/2 inch fuel rails.

What did you do for pump(s)? I will be tuning my similar setup when I get back.. '96 cobra w/ vortech. I used 42 injectors and a 255lph intank + 255lph inline pumps and ditched the FMU. I'm looking to get around 400rwhp also.. I dont think the rails are too restrictive, I've seen plenty of 500+ guys with stock rails.

 

[Stylin Cobra]

I have the same pumps that you do so what is the secret to getting over 500 hp? more boost down low? I do plan on changing the blower pulley.

Hmm not sure then.. only other thing that I can think of why you'd be running out of fuel would be the MAF but the UNIVER should be able to handle it.. I guess I'd just ask around on some of the SVT boards to see if anyone has suggestions.
