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.

 

as above .63 housing i presume you have a 500 intercooler etc?greys will be fine fella as long as the mapping is good!

 

greens will max out befor 380 ,but to be honest i wouldnt bother for an extra 50bhp ,stick with what you got mate

 

aye im running rs500 intercooler etc was thinking i would need a .63.

is it worth the extra bhp?

what power do you think i will be looking at with a .48 and greens?

 

i have greens and a .63,not maxed out, running 27lb but been rr`d at 340-360

 

350-360ish, i have 55lb siemens with a .55 housing and i'm expecting 370 when i get it on the rollers

 

oh right well i would be happy with that! where do you get siemens injectors?

 

ive never seen more than a gen 300bhp @ wheels on stage 3,t34

aww now dont go breaking my dreams there lol

 

i have never seen a gen 350-360 from greens as well!not saying it cant be done but imo i think you more likely to be 340 odd!

 

thats still 330-340hp at crank and thats the fig`s that are being quoted

 

there is alot of people who claim over 400bhp because theyve been told thats what it must because its fast.lol

 

ah,well he didnt say at the wheels lol.
been on the same RR twice with no changes to the car ,first time was 361 second time a month later recorded 344,so i have no idea of what it is at the wheels

 

when i ran my car in,when engine first built,i drove through to ava,changed to greys,chip and 3-bar map in the car park before getting it set up

they set it up at 340bhp@wheels,i drove it home 50miles put in garage and drove back following day for the magazine rolling road day and it made 325@wheels

and it was a colder day on the rolling road day

 

I've seen 360 @ fly

 

a genuine 400 is hard on t34.63, to much bullshit about,

 

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.

 

I got 358 bhp and 340 lb/ft on t34.48 and greens running 28 psi,changed to .63 housing and siemens blacks,going to MSD in october then to rolling road again hoping for 390 bhp.
