been offerd a brand new t4 turbo for 700 is it a good price and how will my car drive greys 781 2wd saff thanks for any info

 

Dan,

I think T4's only make sense if you are going to push them hard I. E. use them with lots of boost (2 BAR held minimum)........Otherwise I think you will only be unhappy with the lag and narrow power-band on your engine spec.

Why not hold on until a nice T38 comes along at the right price to make better use of those grey injectors and 7.8:1 comp ratio?

 

t4 all the way i love it

 

might just do that doug i was thinking prob be a waste on my engine with just greys

 

T4....2bar MAX....any more and you are outside the compressor map and pushing the turbo to hard

 

im running greys with mine and my cams are now forcing the boost in earlier,not as quick as my old t35 but still very impressive

 

..i would imagine no more than 1.7bar with greys!

 

nothing wrong with my car...T4 and greys.....2 bar.

the greys are flat out though.

 

Dave then you not got a very effcient engine 2bar youd really want to be seeing 480bhp and seeing as greys shit out at around 440bhp i can say this

...although i guess at 2bar on a std head and cams youd be 420 max.

 

Phil,

it was rolling roaded at 429, so not too far away if the greys are maxing out.

all standard engine wise too.

not that bad imo.

 

mines at 2.5 bar and the power still increasing...even tho its off the map..

 

This is what I was saying to Dan with my first reply, he'd be better off with a T38 and decent boost spike live mapped in........

OR.....changing the whole engine spec to be a proper match for the "cheap" T4 he's being offered.........trouble is, it then works out as being a very expensive T4

 

I may know of a T38 for sale

Possibly. Your comp ratio and greys would work nicely with a T38 - get a healthy 430-440bhp and less lag than a cheap T4.

Si

 

T4's rock..

I personally thought my car was awesome.. I drove it hard and I loved the top end pull and power.

It prevented me killing myself in my car and kept my licence.

You need a lot of room to pick up speed and come on boost so theres no point caining it around all the time.. only really worth it on open roads and long dual test tracks.

THat price for a brand new one seems quite resonable to me as well.
