Whats up guys got a question..This might be a hit or miss question. I have a 84.5mm gsr sleeved block fully built. Im boosted it soon and im wondering about boost creepage. I bought a full AFI kit. The manifold is the AFI 304ss bottom mount manifold. It has the 44mm wastegate flange on it. Now my question is do you guys think ill be able to hold low boost like around 11-14psi off the gate? ill be running a GT35r82. Because my friend did the similar setup but he has a synapse top mount manifold and he had lots of creepage on the dyno. He had to chop his manifold and throw another 44mm wastegate on it... does anybody have a similar setup and did you guys have any type of problems like this??? need alittle help i just dont want to find out when the car is on the dyno then imma have to take it off and weld another flange on it for another 44mm wastegate... any advice will help... thanks guys..P.s i attached a pic of the manifold... i took it from another thread sorry...

 

I've used a couple of these before. Bottom mount with both 44mm and 38mm MVS gates on it. I have not at all had a problem with their design of wastegate placement. These were used on both a Garrett T67 and a Borg-Warner S362.

 

Nice... That's what I like to hear thanks bud... Anybody else?

 

BUMPPP

 

I use a 38mm tial wg..on a neukin manifold, same design..I dont have any creep at all really

 

I used to run their Ramhorn with a 38mm gate. No creep at all.

 

With a good wastegate and proper spring, you should not experience creep with this manifold.

 

Thanks guys. Anybody have any input on this situation?

 

You shouldn't experience any boost creep with that combo. We have had several people run very similar setups to yours with zero issues. Any other questions feel free to call down to the shop or PM me.
