A while back Kyle from Archer Fab dropped a spoiler about making a IWG T4 manifold for you and I have eagerly been lurking around for a comparison between the old FP 3076 and your new EFR 7670. Have you had a chance to put any miles on the EFR? I’m curious how they differ in spool and if the larger A/R exhaust housing allows it to exhale a little easier.
Hey John! Its Andy from Jersey. Hows it going man? Wondering if you still have my email on hand, because the people following the page would love to see more of your race car! If you have the time, send over some good shots. Thanks man
I don't personally know anything about the Megan Racing o2 housing you speak of. I've never owned it. I don't know why there would be a bolt but is it perhaps plugging the o2 sensor bung?
I only know what I've read about the OBX manifolds in that their build quality is sub-par and I think they're not braced well and so crack over time. If it were my car I wouldn't go anywhere near it but I have the luxury of being able to afford quality even when the prices are nutty. I would personally shy away from it and save your money for an FP. The cast design on the FP will last you much longer than many "cheap" tubular designs as those will crack over time, meaning you have to spend time to pull the whole damned thing off the car and get it welded. The extra cost of an FP over a cheaply made tubular will pay off in the long run.
So finally I got the Megan Racing o2 housing but I have not installed yet. What do you know about it? It came with a bolt, so what is it for? Does it mean if I remove the bolt it will work as an external dump and is going to be loud or louder than if I leave the bolt? what about if I leave the bolt will it work as a recirculated????
thanks so much I am very confuse, I don't know much about it.
Also what do you think About OBX manifold. I would like to get de FP but it costs $350. do you know about any other brands?
P.D: I do not race I just do it for fun!
