S400 low boost P24v puller
- Thread starter Scattered
- Start date
60 at idle and about 50 down the track. Use a FASS 220
I use a schedule 40 pipe cap on the turbo inlet for my boost checker. I use a a CTS for boost and have an Isspro boost gauge plumbed in for drive pressure.

For $$$ your name here
What gauge did you use for checking the boost for leaks? Have you verified the CTS gauge is reading accurately(compared with another gauge?)
Is the CTS reading boost from the factory MAP sensor? Or do you have an add on electrical boost sensor for the CTS? If it is reading from the MAP sensor, I believe it won't read more than 36psi.
I ran into a similar issue with a CTS monitor when I ppumped my old 24 valve. The CTS would read accurately until 36psi and then top out, while the mechanical boost gauges I had would read all the way to 80psi.
Maybe try verifying boost with a temporary mechanical gauge just to eliminate the CTS.

That fass must work well. My AD200 would hold 60 at idle but Wot down the track was dropping down to 20, ended up going to a waterman.

I’m using an Edge sensor in the intake horn. Supposed to be good to 100psi I believe. I’m planning to make it to a pull Thursday I’ll see if I can put my gauge in the intake horn to verify.
Verified all my gauges and sensors are definitely reading correct. Made about 36psi going down the track last night. 50psi drive pressure.. This is with the 87 turbine and .90 housing.
I’m not sure if I’m giving up any power with it making such low boost. Trying to hit higher rpm down the track. Talked to other guys saying they make 50psi+ boost. I feel like I have the fuel for it??
Guess the question now is would I benefit from an 83 turbine like what was suggested earlier? What would be next on the list of things to do at this point?
If I’m just crazy feel free to tell me. Any advice is much appreciated as always

i get 50 psi towing my trailer with my pos
When I put it together I checked that I’d get full throttle. I’ll verify it again tonight.
I’m only getting 1600* EGT at the end of the track. Last year with the VP I was around 1850*. I’m still using 6x.018 at VP pop pressure. Would that be hurting me too? I think all that would effect is retarding timing a few degrees.
I've had the same exact experience with my AD200...what do you do for fuel filtration?

Ran a inline fuel filter, one of the cylinder ones dont remember off the top of my head. I think it was a 10 micron?
Ill look and see if i have the info yet.
