Any body using the godspeed cast iron top mount manifold? I don't know why I like this manifold so much. http://www.godspeedproject.com/honda...-cast-manifold
Does anyone know how much horsepower these manifold can handle before they crack? I want to use this manifold on my build.

 

So you're PLANNING on it cracking?

 

That's not how I meant it. I meant what are these manifold good for? 200? 300? 400? I'm shooting for the 350-450 HP range on my build.

 

I wouldn't trust **** Godspeed puts out.

 

That's what I was thinking. Cheap is usually ****.

 

If you like that manifold look for a spa cast topmount. Much better quality.

 

So you know its cheap **** yet you post and say you want to use it

I'm confused

 

Well at least your some what heading in the right direction now from wanting 600hp. You can find a way better manifold for that price for the hp goal your looking at.

 

Just FYI if you type in b18 cast top mount or d16 cast top mount on eBay depending on your application a lot of the spa mani's will come up
They won't be titled spa but if you read the description they will say warranty goes through spa
Godspeed probably bought that manifold from spa and are selling it

 

I wanna use it because I like the way it looks. But if its gonna crack and what not then no I don't wanna use it. That's the reason I posted this is to see if anyone has used it before

 

They dont crack from power...they crack from heat cycling, vibration, and the weight of the turbo sitting atop a manifold made of sub-par piping

 

co-sign

also, you shouldnt go on "cool" something looks when it comes to performance

 

But he'll do it anyway. Half the reason people get ramhorn manifolds these days is the cool factor.

 

Someone lock this already please

 

 

Hey hey I have a Ramhorn but I'm making 382whp

 

You know what I mean.

 

its the same thing as a Spa. cheaper if you get it off ebay

 

its not the same thing the quality is sub par and the wastegate hole is crappy

 

Says the guy who is "new to the FI". How would you know?

 

yo bro just get the manifold. godspeed isnt shitty. i have their wastgate boosting from 5psi to 22psi with their 6 psi spring and my e boost controller and it holds boost perfectly, i got their inter cooler that drops iats pretty quick and at least like 12 degrees after every pull no matter how hot it is(i datalog my car so i know, not just pulling numbers from my ***) and i have thier 60-1 turbo with upgraded wheel and im smashing on my friends "garret" powered gsr on e85 with my ls turbo lol not even vtec, and also smash on pretty much anything on the road including new GTRs, supras, rx7s, vettes, new 5.0 stangs, and camaros. and again not pullin those out of my ***. been turbo for 4 years. on public roads i have only lost to like 4 cars, turbo type r, new srt8 charger with fat nitro shot, evo on 36psi with e85, and a z06 that could only beat me with spray.

 

i have seen that manifold in three different cars and all still have them. no cracks or complaints. but they did tell me that it was a bitch and expensive to make the downpipe cuz it has a retarded angle

 

 

Do you flush your tampons?

 

Answer the question and try not to get your feelings hurt. I repeat, how would YOU know?
