The Sprintex kit felt great at higher RPM but at low rpm I could never get rid of the hesitation/bunny hop. At first my tuner said it was air leaks so I took off the kit and fixed all the leaks but I still experienced it to some degree. A prime example was 3rd gear at 2500 rpm... i'd press on the accelerator and the car would bounce until it reached higher rpm. Granny driving/low rpm driving was just a pain and so unpleasant. I'd also get huge RPM dips when taking off from a stop unless I really laid into it.

After having the Sprintex kit on for almost 2 years I have recently gone back to stock and WOW.. it just feels so much better as a daily driver. No more bouncing/lurching. The torque dip sucks of course.

Before I take the plunge and go a different route (Edelbrock/Harrop) I thought I'd ask. Thanks



Maybe I should just go turbo!

For comparison sake though, @Rifle was just done right before mine and he has a full catless exhaust, just got the flex fuel kit and was running E85 (not sure if it was exactly E85 since he still had some 93 octane left in his tank) and has the intercooled Sprintex 210 kit with a 69mm pulley. His made 263HP/213TQ (uncorrected) I think. So his E85 and full exhaust got him 33HP over mine, same tuner, same day, same Dyno. (oh, and I have an AT, if that matters )

I was told a "corrected" dyno would be about 10% more, so 253HP for me and around 290HP for him, but I may be wrong.

Maybe @moto-mike could give a better explanation than me. As for the run file, I would share it if I had it, but I do not. I suspect Mike has it.

I do have a log file that I took on my way home that night if that's what you want to see?
263/213 on E70. 95F intake temps as well.

The weather played a huge factor in our numbers, I believe. Humidity was awful too.

@brianhj, the only comparison I have between the two is the fact that I daily drive my 210 with the 69mm pulley and I've ridden in @BirdTRD's edlebrock pre-dyno. I can say, the Edlebrock feels more fluid, yes. But I still feel like the Sprintex has a more aggressive pull behind it. Plus, you can't get over that whine. :p

I've had it on two cars about a year and 20k miles thus far. Finally went E85 and it's a whole new beast!
