Just wondering, what is the max. power anyone has made with a good quality log manifold?

 

590 here on a pfab

 

I know its apples to oranges but over on evom guys are putting down around 600 on the stock ported log manifold.

 

to be hones the only thing that stopped us from making more power was the rc 1000's and e85 lol with the 98% duty cycle lol

 

^i believe it. I personally think the only diff in a tubular manifold is going to be a little faster spool and maybe a few more hp, but the logs seem more reliable and don't crack as easily.

 

i switched to a top mount and picked up some but i also went to a pt67 turbo so im stuck till i drop in them monster bank breaking id2k's lol

 

inlinePRO made 900+ on Matt Keller's integra years ago.

 

log manifolds don't work well at all on h22's.

 

Have you used one on a built H22? Just wondering if you could elaborate on your answer from some sort of experience with it - Thanks!

 

Thats what I was thinking too WideBodyRex but it seems like people always say that it will not make power will not spool correctly, etc. etc. Too much he say she say on ALOT of forums about Logs until someone shows up with 500+ on one lol.

I am just tempted to keep my LoveFab Log and try it out to see what happens...

EDIT : I am going to try the log and see what it can do - if its gonna break, its gonna break!

Wow that PFab looks very very similar to my LoveFab And fantastic numbers there man!

 

My friend made 380 to the wheels with a log and a t3/t4

 

I just made 660+ whp on a InlinePro with a 6765. Spool isn't too bad, but could be better.

 

It all depends on the turbo.. Just make sure you size up the turbine whenever you're looking for big power with a log or very short runner manifold.

You'll see the trend that a lot of the factory turbo cars using log manifolds, always upsize the turbo for whatever power goals in mind. Logs can make power, as long as the manifold design is not flawed (separate exhaust paths into the turbo, or with a proper merge collector).

 

I was under the impression that tubular's flow better and therefore will make more power up high, but a log will spool/respond faster due to the smaller internal volume of air to compress?

 

i got a b-series inline pro if anyone wants it.....
