Default Hooker LTs dyno results

Ok, for all those that were wondering if the Hookers will put out as much hp as the FLPs.

Before Hookers:
328.3 rwhp/327.8 tq

After:
357.4 rwhp/353.1 tq

The end result is a gain of 29.1 hp and 25.3 tq.... <img src="gr_eek2.gif" border="0">

This dyno was with a custom Y-pipe w/ hi-flo cats. Anyway, I am very pleased with the gains.

Although I think some of those gains are the result of your cam being suffocated a bit...I wouldn't expect more than 20rwhp on a bolt on car only....my .02

las vegas hawk,

I'll be putting these on next week and my car is lowered 1.5" Im going to do a 2.5" y-pipe with cats and I'll let you know how the ground clearance is with mine. I'd love to give everyone an example of before and after of just the headers on a bolt on car, but it would cost me a small fortune in dyno time. I'd have to dyno now, install the headers, dyno and then install my cam and dyno again. We'll see...

I hope to see the same results as above though, those are nice gains. what are the specs on the G2 cam?

The Y-pipe is 2.5 inches, mandrel bent, Catco cats, and has a flowmaster collector. I will get my digital camera out today and see if I can take some good pics.

I agree the cam was a bit restricted before I installed the Hookers and my gains are reflective of this, but I'm sure the gains will be close to 20hp on just a bolt-on car.

My cam specs are 222/226 .566/.569 114 LSA...this cam is smaller than Ram Air Tony's (G5 - 392 rwhp) but I think if I had computer tuning, pulleys, and ran the dyno with open headers I would have similar hp numbers with my M6 vs. his A4. What do you guys think?

Pretty nice gains. With the cam you will see more of a gain going to headers, but still very nice.

However, IMO you should be making more power than that with the cam you're running and Longtubes. Have you ever a-tapped your car? Any knock? Whats your air/fuel? 02's? IMO, you should be in the 365-370 rwhp range with a cam of that nature and the LT's. With an LS6 intake, you should definately be in the 380ish zone. I really think you have a lot more power potential with that setup.
