and found this..

just seems a bit pointless as a single wastgate should flow 500bhp shouldent it??

2.8k for a manifold, twin wastegate's, GT30/GT35 turbo and downpipe+screamer pipes seems like a good prise though..

view's? opinions?

 

It has twin gates because its twinscroll. You need 2 gates to regulate the boost properly on a twinscroll setup.

 

Doh!!!!!!!!!!!!!

 

Interesting.

 

Work of art really.

 

its cause its twin scroll. pots 1 and 4 are joined and pots 2 and 3 are joined, it removes the unbalanced turbulance to free power due to the gasses running smoother is prob the easiest way to discribe

alot of newer cars as twin scroll turbos aswell as alot of new design turbos such as the latest impreza

its a cool idea tbh,,,, though alot of extra work but should improve the spool time of turbos

 

Spool times can be as much as 600rpm lower with twinscroll. They use a twin entry into the exhaust housing and split pulse manifolds to drive the turbine wheel more efficiently.

 

notice us scooby boys like this system,,,, as its PISS easy to copy on out engine set up pmsl

external wastegate is also perfect with our up and down pipes,,,,,, gotta love scoobies ( apart from the fucking shit wanky chocolate 3 gear !!!)

 

Isn't the 35 twinscroll only available in .78. Would be a crap choice of turbo on 4 pot'ers around the 2000cc mark. Would make for a mint surge moster then if you somehow managed to map out some surge it would be hellish restrictive top end.

I'm full of shit, you can get a 1.06 twin in a t4 flange, that'll work.

 

Get a Holset HX35, job done.

 

I use the GT35 1.06 T4 flange on my Cossie set ups, awsome full boost at 4200rpm 2.6bar and no surge, The diveded housing pickup up 400rpm peak boost and the transisional responce is awsome to say the least.

Fit a 6 speed

 

i cant justify 2k on a second hand gearbox for a car worth MAX 4k just dont make sence at all,,,,, it wasnt me that done the 3rd gear anyway and i can get my old box sorted for a few hundred quid that has lasted 3 years

imagine paying all that and it still fails.... id cry so much i wouldnt need a piss for a month

 

Im lucky and have a 6 speed as standard. Im fitting a single scroll gt35r to my motor. buy then i do have 2.5l to shove it along with.

 

Is it just me or that look a mission to actually fit to the car....lol

 

not really,,,,, drive car to st albans,,, hand over keys, order cab,,, go shopping in st albans,, get a call off Rob and get cab back to SCC and pay bill


cant get any more simple tbh wouldnt you agree
