Intake Manifolds

[BoostedBB6]

with stock typeR head and 11.6:1 compression. what would be the best intake manifold on the race track (road racing)

blox
skunk2 pro series
edelbrock victor X

In all honestly, I think given your recent posts you need to do some more researching on your own.

Case in point the Mugen intake thread. If you even did so much as a google search, you would have found it had a velocity stack.

In this case, you would have looked up the Edlebrock Victor X Intake Manifold and found that it is used in boosted applications.

However, to answer your question in this thread, you should keep the stock intake manifold. Why, you might ask? Well, your not going to gain anything. Until you really start pushing an NA build, you wouldn't see the benifits of running an IM. Same things with certain cams, you wouldn't put some Pro 2's or Buddyclub 4's in a stock bore/piston/CR setup. Why? Not enough compression to support the cams, and thus a lose of power over the stock units. I believe you will see the same issue here. Your going to be running stock compression, and a mostly stock class. Your money would be spent wiser in other places than an IM unless you bump the compression way up, and run bigger cams (even then you might not justify the cost of it)

I'm not by any means knocking on you, but you seem to not have a lot of info on these cars and parts. My suggestion to you, to get the best support out of "us" would be do your homework and then make your post/question.

I knew it had a VS from looking at the kit. I just didnt know if anyone ran them and had a hard time seeing the benefit in a 700 intake tube.

What you say is completely correct. I did however ask the question because some sites claim that it helps in higher RPM range if anything. Ive done a whole build on my bb6 prelude boost, nitrous, na. done it all and yeah the manifold really doesnt seem to benefit until you really push some serioues air. But thanks, thought id drop that question. Ive also noticed how 'open' Honda Challenege is with the motor swapping and internals swapping. Seems a bit too competitive for my unstanding and budget, I may stick to a tighter rule book to make it a bit easier to stay on the edge of the B18's performance.

I have no "quams" with either of mine. I'd do it again in a heartbeat, and not for the bandwagon either.

As for the IM, in my personal case I would not have changed mine out recently, had I not seen vaccum being sucked at 7k RPM's. But I also have a built head with some pretty serious cams in it. I think that's what caused my need for more air volume, and now that the setup is in my other car, with a much less restrictive exhaust, I thought it would be wise to change it out. Personally I went with the Edlebrock Performer X and 65mm TB. If I need more, I'll try 70mm TB and if I still run into issues there, with not enough air volume I'll look into the option of ITB's, but that's a very last resort.

HC's rule changes, and lack of support in the FL region have caused me to change course with my car. If you want to be competative (sp) look at spending close to 100k a season. I just can't justify that. Ugh...

[BoostedBB6]

100k in a season is way out of my wallet. After looking at the HC class Ive noticed that if you want to be competitive you need a built K-series. The flexible rules about honda interchanging parts have taken away the car's real heart (B18c5) so Im going to stick to the SCCA ITR where its tightly classed and leaves room for other cars such as BMWs, RX-8 (even though I think its classed wayy to heavy to be competitive) and mustangs. Im hoping to finish this deal buying a shell. Need to find a place to put it while Im finishing school.

why the performer X and not the Victor? top end power ftw

[coolhandluke]

The Victor-X is much larger, and is only recommend for high CR or larger bore NA applications and boost setups. The Performer-X is your best choice. I have just purchased this IM and the matching TB from Edelbrock for my build.

Dave, what class are you racing?

[Dave_B]

Dave, what class are you racing?

Originally, I was looking into H2 in Honda Challenge. Then after adding up everything, and the class rule changes... I decided to go "midget class"

Basically, I'm now changing gears and building the car for me, to have fun with. I no longer plan on racing W2W anymore. If the car fits in the rules for HSR, then I might run that but I haven't looked at the rules, and I'm not building the car to any spec.

And Ryan is right, the Victor X is designed for boosted and way high CR cars. I can almost guarentee loss of power vs. the stock unit if you went for the Victor X IM.

[BoostedBB6]

thanks for the advice. I was looking at racing H2 but the rules are getting a bit too flexible for my budget. I will just run stock manifold in ITR since its the rules. Port matching will the best I will go with that
