T04s v To4r

[LRP]

whats the differnce between the too turbos i know the hot side housing is bigger on the R is the shaft the same ?? only reason im intrested is i hav a s and im not running a bov , davehg has a r and hes been running without one for ages and has had no problems?? also if i wanted to go upto an r can i just change the houses ??

[davehg]

ill show you the difference on the rolling road mate :god

[davehg]

the to4s has a lower high end output compared to the t04r

[Grizzly]

But spools quicker

I\'ve driven Rx\'s with Both HKS Kits fitted and i felt the S was the better "on the road" Turbo but it depends if you are wanting numbers or Drivability.

Also it depends what turbo you are talking about too, There are so many Turbo\'s out there that are suposed to be S\'s and R\'s in diffrent trims and core Types.

mines a garret and yes it spools from very low rpm good for road use but as im still running in havent yet taken it round the clock to see how it holds boost cant wait.....

[strange_days_uk]

Oh........   it holds boost, don\'t you worry about that !!


:WaveBye

My to4r has a pretty small hotside and I\'d say it\'s good on the road, some noticable lag and pretty good power from modest boost level.

[davehg]

again it also comes down to the hot and cold sides.

again it also comes down to the hot and cold sides.

And how you drive it.

TO4R has a bigger compressor so puts more air in the engine than the TO4S.
It\'s a very small difference in size. the TO4S traditionally only comes in 1.00 hotside the TO4R traditionally had .81 .96 & I think it was 1.05 or 1.15.
I will be tuning a TO4S in about a month from now, with a very small street port, so will remember to post dyno sheet. I don\'t think there are many running a TO4S over here so probably hard trying to compare power output & boost response to a TO4R.

I have a T04S and the power delivery is awesome, on the road or track this is a GREAT turbo, too weeny for drag but that aint my bag

[strange_days_uk]

I really need to do a power run soon, then can post up my results.

I get a really smooth rising power curve, with full boost by just shy of 4500 rpm.  1.0 hotside..  Standard port.

[Red and Single]

I get full boost around 3750 odd, but I have mild street port and recall my hotside is smaller too....I\'ll check tomorrow.

At reworx, I made 335rwhp at 0.85bar, stock injectors mean thats all she wrote, I\'d like nearer 400rwhp though :burnout

[n4bes]

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...............
lol

[strange_days_uk]

Carl and I reckon mine is making 400 fly maybe more.

Defo need to get a power run....
