New Garrett Gt3540 Internal Gate Is Here + Dyno Results

[Busky2k]

Haha no probs, glad to see you tackled the problem with some thought! I wonder if ATP will improve the flanges in the future...

tru but i guess it depend on what they were thinking when they designed the one that you have shown.

a lot of engineers design things in two dimensions and wont change unless forced too.

At a guess I'd say its cheap and easy to make two round holes and from the outside would look spiffy to some .

I reckon if I was going to make one I'd do something similar to what HKS did with the Pro S style dump pipe . I'd leave the divider in the flange plate and section (cut in half length ways) a smaller section of pipe and weld it to the side of the main outlet pipe . This gate vent path section would need to be fashioned with the nockometre to match the flange plate and probably Mig welded in place . The main turbine vent tube would be a mandrel bend and so would the "halved" wastegate vent pipe .

It would be nice if the flange plate was an exact match for the IW housing inc the divider , if the gasket is close enough it could be used for a template to laser cut provided the ask was for a reasonable quantity not just one or two .

Cheers A .

I would check to see if the Ford versions gasket has the divider section because their housings divider does not rise to the same height as the Garrett Housings . At least thats what my pics show .

what did you do for a dump pipe?

[Z24O]

just as a matter of comparison,what was the boost threshold for the GT30 vs the GT35

was the swap worthwhile for street performance,do you notice the 40+ extra KW all through the rev range or do you have to lean on it harder to feel the extra with the GT35

there's no doubt the ET/terminal velocity would be significantly different down the 1/4,but that's not what i'm getting at

which was the most fun as a daily driver?

cheers

ps let me know if/when you are looking at getting rid of your GT30 and how much you are chasing

[dangerman4]

on a serious auto then the gt35 is very smooth.

on a manual i would say its to big for a daily.

the gt30 felt a lot more agressive thru the mid range, and would well suited the manual skyline.

i will post up all the info on the package that im selling once i get the turbo back from gcg.
