Out of fuel pump, adding a AI surge tank with a second staged walbro 400, 4 ID1700s and 25-30psi. Probably turn it down though, and switch to a 8374. This turbo is moving to our roadrace FD3S chassis( currently runs an 8374 @ 31psi).

Sweet car, you guys always build nice stuff. Do you happen to have any EFR 9180 1.05 in stock? If so, whats your pricing on them these days.

Thank you! All of the EFRs are in stock.

Looks like the 'perfect' street turbo................

I have it up to 20.2 psi now and I also added 3 more degrees ignition advance. I can tell the turbo is starting to wake up... 2nd pump and bigger injectors next week..I have a feeling the clutch will fry when I try for 25-30psi...

@ 32 seconds there is a visible flame from the outlet of the down pipe/turbine housing junction (under the heat shields)...... leaks there ?

We suspect so. I have no idea why. We are now using the updated EFR turbine housing discharge flange( which is sanded flat after welding). It will be inspect it when we heat shield the DP/MP. When it was first started the system had zero leaks that you could hear or feel..

It's a real pity they don't use a stepped design, such a nice turbo otherwise. I notice there is a taper put in all the discharges, a real simple solution is to do a mating 'male' taper on the outlet flange so it locks against the taper and the flat, it will help for alignment as well.

It's actually design that way to seal on the taper, not just the flat. This will eliminate any leaks over time.

They used to sell that design, and it also leaked! My guess is the machine work on the DP flange is not ideal( there was slop) or the welded tweaks it enough where it needs re machining again!

You do them (Elliot's company) everyday, but when I do these its clamped against a dummy housing and the weld of the flange is at least 1 inch away from the sealing clamp surface. No one though makes a flange like this cause it costs more money to make it this long (tight ass's).

If its not done like that then it will *always leak* and is near impossible to rectify (if its a taper type or stepped type *Tial*) after welding. :smash:

One of the only decent clamp flange styles is the HKS version (on their T04Z's T51 turbo kits), very thick and resistant to deformation in service on engine and also during fabrication.

These are practical things you can implement to solve this problem that work long term.

I have fixed the leak on this car, curious to see if its lasts now( especially since we are 30psi).

That's some serious response..... I MAY have to pick one of these up and move the current turbo to the 'Vert :rofl:
