I have a 2wd cossie with 3" Mongoose, KN, Montune Chip, Turbonetics T34 ar.48, grey injectors, low compression pistons, and ported top (???). Had it on a rolling road and the results were 350bhp@6100 rpm., and 417nm@4400rpm. 1,6 bar.

Will a ar63 exhausthouse be a good upgrade, or won't it make any differance?

 

corse it will change it

 

depends what you want out of your car really mate.

for better response and less lag, 0-60's i'd use the .48

for more top speed and more power on boost (but with a little more lag) go for the .63

You would need a remap too if you decide to change

 

hi mate,im running t34 with .63 on my 3dr,it,s stage 3 and 500ic very much lag compared with t3 and stage 1, about 3700 rpm before anything happens,but when it does it,s a lot stronger

.63 pulls like a train when it get going, right up to the max revs!!


Dave.

 

If i buy a .63, should I buy BD-14's too?

 

I have not got them!

You need to have pocketed pistons for bd14's........BD 10's i think are fine for normal pistons.

What i mean in the statment above is that you don't run out of puff at top end like you do with a .48 housing.


Dave.

 

i was in the same boat mate, i went for 43 housing as i hate lag but now i am restricted to under 400bhp until i change it.

but my car is running sweet and rapid at stage 3

 

just changed my 48 for a 63 well worth doing not that much lag

 

Not as bad as people say is it.


Dave.

 

im running -63 with greys, 500 i/c low comp, worked head and
got 382bhp with fooked exhaust and tesco petrol, dont find
it much more laggier than when i had a -48 and like said
above it pulls all way to 7k

 

is this with a t34 comp housing?

 

As I told you before Triggerhappy, bigger AR - more power on top.

 

Yes!

A .63 housing from a big turbo es cos.


Dave.

 

as above i've got similar spec to people mentioned

Low Comp
Worked Head.
T34 with .63

and got 407bhp and 402flbs

 

Don't think this is gonna happen anyway, Jens said i would crack my block if i increase the power any more?

 

Don't think so mate.

Have you only got the 205 block .


Dave.

 

I have the 205

 

broms car was over 500 bhp on a 205 block
