back from the dead.....

so i am dyno'ing on 9/9.

what you guys think about going down to a colder plug. i heard wispers of 3-5rwhp from going colder. thoughts?
colder will always help with any motor, but as far as adding hp I think that is directed towards boosted or built motors. However you can always get better plugs, might help get a better spark to burn out those couple hp's throughout the rpm range

at our Stock * cr * dont really need colder plugs. But u should buy the header and dyno it lol
i was so close to the megan header but i recently had a converstation with a megan header owner through pm, and he lost 15whp in a boosted application. sadly i have to agree with the saying, "you get what you pay for." hell for 1200-1400 bucks i'll het ITb's and Ems!

Well, my Megan test pipe is in the mail...scheduled for delivery on the 2nd...when I'm supposed to be racing in Brooksville...I might wait to install my test pipe, and then race on Sunday...I'll set up a dyno for the following week, and see how much closer I catch up to you guys

I've been talking to Todd at 2nrwerks, and he HIGHLY recommended the megan header...he's been putting it on allmost all of his supercharged customers cars, with great results. I'll be getting one, more than likely it will be the next mod after the test pipe.

Is this the same guy who also had a boost leak? And ran the dyno in unoptimal conditions?

I think I'll still get one just for the weight savings and the big primaries. I think it doesn't looks as smooth as the J's, but its about $900 cheaper.

Unfortunatley people (like me) who buy a $350 header, don't go to the dyno that often.

Megan's header is still cheaper than Ricks...but nobody's done a megan header dyno on a N/A motor yet, so we really have no friggin clue...

Megan's website has a dyno of their header HERE , but they don't show a baseline for comparison.

Rick's looks good, but there's one problem from what I understand. The header was made after Mugen's AP1 header.

Now that Mugen made a 2.2l header I'd like to see a Rick's design off of that one, for us with an AP2.

I don't know what the gains are with Rick's and a AP2, I'm sure they are decent, but they probably could be better.
