I'm taking off all day tomorrow to work on those manifolds before I send them down to vsr. Them thangs are going to flow like mo-jo!!! More than likely I will smooth out the intake runners as well. Pics tomorrow!!!

Before and after. I may have loaded the after first. lol
Went ahead and grinded one tonight. Notice how the gasket doesn't cover any of the exhaust flow now.?

Hey gtm this is the way it should have been done!!!!!!!

That looks nice!! ^ Damn I never noticed that. Great call

COSMO · 03-18-2014, 11:40 AM

Thanks, I'm working on the other one right now and will post pics later..

How sharp is the edge on the inside of the flange? Did you round that off? Pics of these kind of things are always kinda hard to see.

COSMO · 03-18-2014, 11:45 AM

Sharp but I took my time and grinded it down for a smooth transition... Will take better pics later..

Here is a pic of the driver side gtm exhaust manifold before and after the grinder. Who wants to bet it's going to flow a lot better now!!!

This is easy power right there. Kind of shows the level of workmanship that goes into a GTM branded product.

UPDATE: Just got off the phone with bobby at vsr and my built motor goes out tomorrow!!!! And for those wondering those gtm exhaust manifolds have been perfected (thanks to me and my grinder) and being shipped to vsr tomorrow to have them make better one's in which hopefully won't have to be drilled or tapped. Opening that up the exhaust manifold that 1/4 of an inch should help the flow a lot. After measuring it's like 20% bigger now and matches the gasket.

Good stuff!

09nismo498 · 03-18-2014, 07:23 PM

sweet, looks good man. I can't believe they didn't make them like that to begin with!

Rusty · 03-18-2014, 09:32 PM

Hey cosmo. How far into the port did you grind?

COSMO · 03-18-2014, 10:04 PM

As far I could reach to get those sharp edges down for a nice even flow. I will take a few close up shots tomorrow but trust me it's a lot better than what it was...
