Just curious what brand you switched to, performance difference (i.e., e.t.), and any comments you care to make.

Thanks,

Jim

 

anyone?

 

I went from SLP's to Kooks... We have replaced FLPs, SLPs, Hookers/Jet Hots, MAC Mids, all in favor of the Kooks. We see 355-360 rwhp on a bolt-on tuned car with 1 3/4" Kooks. We saw a 12hp gain on a car that we swapped mac's out in favor of kooks.

Let me know if we can help you out further.

What did you gain from going to SLP's to Kooks?

 

id be interested to see jethots vs kooks back to back, no other changes dyno.

 

my friend gained 8 rwhp on back to back dynos by switching from slp long tubes to the QTC long tubes (grott design) hope this helps

 

I had a set of mac mid's that I just replaced with FLP's
and one know any dyno #'s
How much more I schould gain. from mac's to FLP's
????????????????
thanks

I went from Macs to Kooks

Thanks for the replies!

Does anyone else have any e.t., mph, or hp comparisons between SLP LTs and other brands? Preferably with no other changes (i.e., baseline run with SLPs then swap headers, without making any other changes, and make another run).

Thanks for the info,

Jim

 

a guy i know with a 99 firehawk only picked up a few horses horses going from SLPs to Kooks...this was on a head and cam car that made 400+ rwhp b4 the swap.

 

19rwhp going to 1 3/4" stepped Kooks over SLP LT's. 445rwhp H/C car though. I would say 10rwhp would be an average.

 

lonslo before/after dyno?

 

Honestly it's been awhile since I did the back to back dyno comparisons. Best I remember with the SLPs was 424. Little over 440 with the Kooks.

 

area under currve or peak?

1 5/8 stepped to 13/4 or otherwise?

 

GrannySShifting,

Good question. I guess I'm trying to figure out which headers will get me down the quarter mile the quickest. So I guess area under the curve would be more applicable.
Eventually, I would like to have a high 11 second street car, so I'm trying to figure out if it's necessary and worth it to replace my SLP LTs with another brand?

Thanks,

Jim

 

Not necessary at all, but I knwo guys that made money switchign form their SLps to Jethots or break even at least, and the groudn clearence is much better, and I dont here guys sayign they picked up much power from Jethots to Kooks yet
