T04s v To4r

[Grizzly]

I\'ve never quite understood why they put a Smaller exhaust housing on the R than the S? surely its a Viscous Circle (bigger Comp means more air there for more Exhaust gasses etc etc) so would\'nt a .81 strangle the Turbo to help the Response? its just not as balanced as the S.

Plus just another useless fact i\'ve picked up but did you know the Garrett S was originally designed for use on 80\'s F1 cars that\'s why S\'s seem to have always been about but R\'s are a recent Addition to the range (Last ten years or so), just goes to show how old the Technology in the Garrett T range is

Cool fact.  I know the S has been around since the 80\'s

Probably 400fwhp at 0.9-0.95 bar.

I\'ve got the to4s, dunno bout hotside tho....lol. It\'s 320 fwhp running 0.6bar.

Going to Pips to get the boost turned up, already got boost controller, pump and fpr to go.I\'m running 850cc primaries too.............dunno wot i\'ll end up with...............

I\'ve got the XS T04S and am very happy with it. The couple of people who went for a ride at the activity day last month can comment on it.

The S should spool quicker than the R, but the R will have a higher boost top end.

Currently setup for 10psi, but feel the need for more.

cool cant wait to get mine set up now its run  in to4s street port 1600cc secondarys  standard primarys o44 pump v-mount 44mm tial wastegate to atmosphere greedy boost controller water injection going to be tested in a mth or so guess\'s???

Well if it helps, a mate of Mine has a WGT Extended port engine (fairly Mild one) and simalr mods as you (without WI) and a .96 hot side on a S, he recently ran 380rwhp at 1 bar.

Driving wise, His car uses a PFS SMIC so its not the Biggest Intercooler you could buy but has fairly short IC pipes, so for what he uses it for (Street and the odd track day) its spot on.

Fish when you say XS turbo do you mean XS Power turbo and would you reccommend them, what spec is the turbo?
Sorry for all the questions but my T04s is blowing oil under boost so need a new one and for the price of a rebuild I can buy a new one.
 
Thanks

Its the XS Engineering in the US turbo, and not the XS Power (ebay) stuff.

I would happily recommend it.

Thought as much you still selling your\'s ?

I mapped street ported to4s with a .81 a/r a few months back.
It had 420 or 425 fwhp at  .90 bar  and 500fwhp at 1.25 bar. Never seen a to4s with that size a/r before, but was told when it went on a track day that boost is pretty much instant.
Seems like to4s is more than capable for a small - medium size trubo.

bloody ell! hopefully my t04s will be capable of that! ive got a 1.00a/r
 
what were the intake temps like at 1.25?
 
what porting and other mods did it have?

It had large street port nothing too crazy, trust front mount, greddy elbow hks twin spark, water meth 50/50 mix, magnecor ht leads, some denso fuel pump I think supra, 950 pri injectors 1680 secondary, the usual stuff intake temps we\'re between 25- 30c

was the WI used to tune or just for safty? also why did you use such big primarys?
 
and i presume a PFC?

Water injection was used to tune 850 pri is quite the norm I would consider 1000cc pri big. Yes tuned with pfc. I only built the engine and tuned the car the rest is down to owners personal taste.

The only reason i ask i was under the impression 550\'s and 1600cc injectors supplied enough fuel for 500fwhp.
 
I was hoping for 400rwhp
