Thanks Jedi .

That's what I thought. How were your AFR's up top?

Low 11s if IIRC

Nice. Think you left any power there?

None .................... It really did hit the wall . I'm going to fit a vac. gauge to my turbo inlet and see if it's going into a strong vacuum . That seems the most logical reason for it just talking with the guys at PPRE.

Although ............... I have no doubt it would have made another 20-30 more on a cooler day .

Time for some nitrous :)

OK .... found the problem !

Definitely the turbo intake is too small . Drawing 6-7psi vacuum at peak rpm .

Now ...what to do about it ????? It's tight as a fishes ar** down there .

We have a Turdblown engine mount bracket I could ship you. It was only installed for a day or so.

I'm thinking of taking t back to the builder and shoving it up his **** cuz i told him it was too small from day one . Then again ........... it's all he could do so i guess it's my fault :(

Yeah that is a tough one.

I do have this lying around ... 3" ID

^what is it made of?
it gets pretty hot down there

Probably pvc ... not going to be much good . But it got me thinking ......

Auto Silicone Hoses - Silicone 2 Ply Air Ducting - 76mm - Blue Air Intake Hose - 1 Metre to 4 Metres

Good to 325C .... ordered some ... looks promising !

Man that thing has got to be a pain to get in and out...

I would test a section of that silicone with a heat gun, see how it holds up.

The first couple of times it was . But once i found the correct sequence and tools ..... easy.

I'll wrap some of that silver heat sheild stuff around it where it goes past the manifold ...

If you can't get the intake routing sorted, trying a blow through MAF setup may present other options (and issues).

Man, you were quick to find the limiting factor in the setup. Nice work!

Cheers . Still need to get cool air to the turbo somehow but yeah a blow through maf could offer some advantages.


One big learn from this was that I did find the acceptable limit for 60mm ID intake tube . It's good up to around 320g/s .....

You make me feel like a wuss for complaining about just having to loosen up my manifold for my clutch job :lol:

I was being a total wuss about it till Williard put a rocket up my a*** so I have him to ummmm ................arrrrr ...................thank ... I think.
