Yup, i did hear they are bringing out a 1.10 divided ar for it, i think that may be a good turbo, whats putting you off using the GT35?

 

Just feel like i have a chance to go bigger now and not have to pull it apart agai in a couple of months, plus with all the options available at the minute i thought it was good to explore what i could o.

 

to begin with it was a basic single build, but as i managed to get some decent injectors, Q45, greddy inlet manifold etc etc i thought maybe i should use them more to their potential :)

You're right :) Lee text to say mine made 550bhp and 510lb/ft, will full boost at 4000rpm at 1.5 bar. That's at SRR, in full 'quiet' spec. I'll post up the graph when I get it.

 

nice mate :cool:

 

how do you mean quiet spec? are you expecting more from it still?

 

i think your turbo is very similar to this 91/79 model from what i've discovered today :)

Thats decent power for 1.4bar on stock cams/engine, bung a set of 264's in and i bet you could add 60bhp.

 

I'm happy with it... especially getting full boost at the same time as the T61. Plus, you got to love those torque figures :D

 

For me it wasn't ever about getting high power figures, more having a car which drives well and scares the pants off my passengers.

 

The next stage will probably be a billet wheel, some cams and maybe a built engine (hello 2 bar) but for now I'm just going to drive the tits off it. I should be a good durability tester for the BW turbos. :innocent:

:D nice!!

 

Cheers - by quiet I mean it's not loud lol. I've got a silenced exhaust and no screamer pipe so I can get onto tracks and race the car this summer.

 

 

oh i see, we wont hear you coming by next time then ... stealth!

Does this help to lessen the need to get uprated cams then mate?

 

Still need cams if you want anything over 550bhp, you might make 650 but it will be strangled at the top end, they come alive with cams after 550bhp from what ive seen.

Try it before cams for a month or two then if your still not happy get lee to put cams in.

 

Like jamie says it will feel strangled at top end where are you going to do top end not down the A24 to many cameras;).

 

cameras everywhere dude, A23, M23, A24.

 

the A272 is good and some roads near me in cuckfield/haywards heath! :D
