Mini Rams/Ramhorns that DON'T Boost Creep??
OK, I've done some searching but I thought I'd ask for you guys' opinion.
Friend of mine has a stock internals b18c turbocharged and bought an SS Autochrome manifold, not knowing what it was. So now, ofcourse, he has really bad boost creep.
Setup is:
T3/T04E 60trim
b18c - stock internals w/ b16 head
Tial 38mm wastegate
3" downpipe
3" exhaust
We've tried a ton of things to try to get it to work but are now just at the point of changing it. With a 3.x psi spring, the boost creeps to the 10psi boost cut. So on to my question, which are the AC compatible mini rams and ramhorns that won't creep?
He's on a low budget, so full-race etc. is out of the question. Looking for something in the ~$500 or lower range (new or used is fine). Ideas?

Re: Mini Rams/Ramhorns that DON'T Boost Creep
the spoolin quick4 ac will work but it's $650 and a miniram
for a cast manifold i was always under the impression that inline pro made the best one on the market that had near zero boost creep

Re: Mini Rams/Ramhorns that DON'T Boost Creep
Have heard of these but don't know anyone who actually uses either to determine whether they creep or not. Do you have any experience with either? We were thinking bigger gate as well, but shouldn't 38mm be enough gate for a t3/t04e?
have you used the spoolin manifold? Yeh the price is a little above budget.
I've always heard the same about the inline pro, considering that if I can't find him a miniram/ramhorn

Re: Mini Rams/Ramhorns that DON'T Boost Creep
personally i'm using the inline pro for 3 reasons
1. i won't have to weld it up in a year
2. it doesn't boost creep
3. people have made real power with it
for a street car it just seems like the way to go
that said i'm sure for all out hp production you can get better manifolds but i just don't want to compromise the reliability or unknown creep issues
from what i've heard the spoolin manifolds are a good design but i have not personally talked to anyone with a quick4ac to see about the creep issues. it's almost 2x the price of the iron inline, less reliable and who knows what it's really worth for hp? i have no clue what it would do over an inline or if it's even worth mentioning

Re: Mini Rams/Ramhorns that DON'T Boost Creep
the ss autochrome manifold is **** to begin with. The majority of any decent, well designed turbo manifolds don't creep provided you have a quality and properly sized wastegate.
If 650 is outside of his budget then you arent getting a tubular manifold unless you find one used. Just pick up an eBay cast manifold and be done with it.

And ya the inline pro mani is pretty sick i am going that route myself, cant beat a ss cast mani used

Re: Mini Rams/Ramhorns that DON'T Boost Creep
Getting a new manifold is def a good idea considering SS auto is crap.. Invest in a 44mm wastegate it will help a lot with creep. I have a ramhorn neukin manifold with 44mm wastegate creeps about 1-2 psi depending..

straight spring for testing, solenoid on 0 and 10% duty cycle (normally closed) had crazy creep as well.
You have PM
That's the plan, hunting for a manifold now. Anyone here used boostflow or rc-autoworks?
How was the synapse with creep?

Re: Mini Rams/Ramhorns that DON'T Boost Creep
im using a peakboost ramhorn with a tial 44 and i also get about 1-2psi creep. i bought the 44mm thinking it would fix the problem and it did not, although it helped out a lot. this was on a 2 stage turboxs boost controller, 9ish psi spring i see about 10 psi just off the gate

Re: Mini Rams/Ramhorns that DON'T Boost Creep
If your looking for a quality AC compatible ramhorn look into synapseturbo.com Morgan makes quality stuff and they are not the over the top price of a full race or comparable. They make a beautiful looking AC comp. ramhorn! And tell your friend to stop cheaping out and buy some quality stuff doesn't he see where cheaping out on the SSautochrome got him?

Re: Mini Rams/Ramhorns that DON'T Boost Creep
I'm just trying to figure out why 3 psi. Large turbo, low boost requires very high wastegate flow, flow that will choke a 38. Minimum 8-10 psi won't creep.

Re: Mini Rams/Ramhorns that DON'T Boost Creep
When I realized what manifold he had bought I knew that was the problem. However, it had worked well on 2 previous cars (one of them with a gt30r) without creeping (according to owners) - so we looked at all possible exterior problems before giving up on the manifold.
A T3/T04e 60 trim is hardly a "large turbo", 38mm of gate would be sufficient with a proper manifold in my opinion. We only tried the 3psi spring grabbing at strands so to speak after having the same problem with a 7psi and 6psi spring creeping to 11psi (stock map).

Re: Mini Rams/Ramhorns that DON'T Boost Creep
I build all my own ramhorn manifolds . I never had problem w boost creep. It's all in the wastegate placement... Pm me if I can help w anything

Re: Mini Rams/Ramhorns that DON'T Boost Creep
the quick 4 aka minirams will always have some creep, the collector is to small and doesnt allow for proper boost bleed off. Ramhorns depending on the turbine and wg should be fine unless there junk like ssautocrome or some halfass guy in his backyard lol
Cast logs work well if good design like the inlinepro or blox or spa topmount. all have good wg placement.

Re: Mini Rams/Ramhorns that DON'T Boost Creep
Yes, I think my wording was a bit off lol. It's that it's a huge turbo, but that turbine section requires a large portion of exhaust gasses to be bypassed to maintain really really low boost levels.

Re: Mini Rams/Ramhorns that DON'T Boost Creep
What size wastegate spring were you running?
