Default Whats my limit??

i am currently running stage 3 with greens and t34 .48

i am looking for just over 400bhp what injectors chip etc will i need to get this? i heard the seimens injectors are better than the greys for fuel eco and they just dont dump fuel?

or am i better to just taking the greens to there limit and be happy? lol it will only be for fast road use but would like to say she is 400bhp if you no what i mean!

cheers matty

You won't get near with that turbo mate .48 is too small you need .63 to get close.

No experience which injector is better but i've heard many people say the siemens is better. Although if you keep your current housing then i'd personally stay with the greens.

Agree 100% Jase,

As said, the .48 housing obviously makes a nice punchy car, the .55/.63 will be slightly laggier but more top end, BUT the top end gain will probably not be that noticable tbh, i had a T34.48 setup on my 3dr with a NMS live map, greys and it was one of the nicest road cars i've had, really miss it sometimes tbh..

Choice is yours, but you'll struggle with turbo life too trying to achieve 400bhp on a 34...

dont forget you need to start looking at changing some of the bits INSIDE the engine when pushing for 400bhp also.

a good solid stage3 is a fast car and relatively reliable, i'd stick with mate

if you want a bit more punch then look at going for a live map or similar on your existing setup, this will make sure youre getting all you can out of it and you know its all performing as it should etc.

Agree Jim, people don't seem to realise how quick a well setup stage 3 cossie is, there's not a huge amount of cars that'd leave you in there tracks that's for sure..

Are you happy with how the car goes? If your happy then what does it matter what power the car car is producing?

You wont see 400bhp on a T34 imo. 400bhp is also a shite figure to aim for, 380bhp or 420bhp are better figures to look at if you do want more power.

I'm on a t34.48 and greens and poorly set-up on a standard actuator on Stu's chip I saw 350bhp & 325lbft. With a -31 actuator (I was told the standard one was -31) it suddenly boosted correctly so I expect the figures to be slightly higher for the bhp and much higher for the torque because it boosts sooner now and those figures are dyno dynamics ones.
