thinking of buying a peakboost ramhorn mani for my b18c4! hoping to hit around 450whp just wanted to know will this manifold reach that power goal and will it give a fast spool? have been searching but i have yet to find the answers im after! thanks for looking regards russell

 

yes, peakboost is good

 

Their manifolds are some of the best on the market....talk to Anthony at PeakBoost and he will hook you up and you will make your power goal

peakboost

 

I havent dyno'd mine yet, but craftmanship is excellent

 

anyone had any fitment issues with these? im looking to hit 450whp+ so i will using a fairly nice sized turbo dont really wanna shave the block if i can help it! thanks for looking!

 

Thanks for all the kind words guys....

You will not have a fitment issue with our ver.1, ftw or topmount....

Heres a pic of our ver.1.



FTW Ramhorn



Topmount(not the best pic)


Any questions just pm me

 

nice stuff....its what i'm using on my next build

 

all looks good roll on payday

 

just curious, have you had better results with the ver. 1 compared to the ftw ramhorn? i like how the ver. 1 has more of a "straight" when exiting the head.

good question, that i've been asking myself for sometime now.

to be honest, we've yet to test them back to back.

however, i completely agree with you. the 90* bend of the "FTW Ramhorn" coming out of the #1 and #4 cyl, seems to be much more restrictive than the 45* of the PeakBoost Ver.1.
beyond this, the "FTW" #2 and #3 runners are quite a bit longer and have a much higher volume than the 1 and 4. whereas the PeakBoost Ver1 runners are all within ~1inch of equal.

all in all, both manifolds have been proven to put down awesome power, look great and stand the test of time. in the past 5years we've made well over 2000 manifolds and have only had 4 warranty claims(in the first year of production). pretty good track record if i do say so myself.

 

the ver. 1 i have not seen any other company fabricate besides you guys, i prefer the design because it looks like it is also a lot further more away from the valve cover than the FTW, which can only be good for oil temps on the valve train;

but nonetheless, both designs make power.
