Only problem is the MAF, which, if I'm correct you could just swap straight with an MAP sensor without issue.
instead of removing the maf I'm going to use it for tipin enrichment, seal it against boost and clamp it.

Re: twin TD04 project

Most systems run the MAF before the turbo anyway so they don't see boost. The problem is then you would have to Y the intake to both turbos unless you can tune the car and run 2 MAFs, 1 for each turbo inlet. Going to a MAP system with the hydra or megasquirt eliminates that issue and allows an air filter to be stuck at each turbo inlet and be done with it.

Ineed, however, going with a 2:1 intercooler, run the MAF inline with that one tube to the throttle bodies then Y it off right before the throttle inlets. This way you can use the MAF off-boost and use it for tip-in enrichment, then clamp it off as boost rises.

Re: twin TD04 project

lol since this post my svx water pump went and cracked the housing, got a 2nd svx while i rebuild the laguna, moved across country so i'm a little behind lol

i've talked to a few people and TD04's are still too small even for a TT setup.
so since i need to rebuild my engine, i'm going full build from the ground up might run something like twin GT35R's

I will document the build once i get around to having spare funds for it.

Re: twin TD04 project

GT35's?! What kind of power are you shooting for with those?

I've always pictured a pair of GTX28's with V-band housings... Mmmmmm...

Re: twin TD04 project

twin 35r's cmon. we can get 700HP out of 1. that and there too huge to fit low mount.
2 td04's will comfortably break 400hp atw.

good to hear you havent given up though.
a 1000hp+ svx would be absolutely epic though if you do fit 35r's

Re: twin TD04 project

A couple of VF39's will certainly meet your needs.

Even a single TD04 pushed to max will make 280 whp on a 2.5 Suby. That's theoretically 560 whp with twins.

Re: twin TD04 project

my choice would be twin vf34 if aiming for 600ish. or 2 GT2860's wit hth e .6 rear housing or similar. though the garretts have a much bigger housing to fit in underneath.
