dissapointed with t04r

[hairyhoover]

think hes on a t51r now!

[Jimjitsu]

Never mind the figures as long as its fun to drive:Thumbsup!

[BlitzBoy]

ssssshhh lol

I would stick with the R my man the Zed is good but you will only gain maybe an extra 20-30 bhp across the power line per same boost and quicker spool.

Brian ran the R up to 1.3 BAR to 1.4 BAR I believe

My R was rapid ran loads of 11s with that turbo

[strange_days_uk]

this is 0.8 bar on a T70 with large street port




I would expect to see something similar with your setep

he should be a touch less your turbine wheel is 70mm.... to4r is 66mm i believe.
 
is that flywheel figures mate?

what spec is your TO4,  i reckon your main problem is that your hot side is way too small!   your power is tailing off at 5k rpm but you are at max torque at a little over 3krpm.  That indicates a hot side that is to small. What are the A/R\'s of the turbo.  There is a no amount of fuel tuning that will sort that out!   Are you sure its a TO4R not a TO4B

[mattywhitt]

I am not sure on the hotside, it had better be a t04r! Thats what i paid for, Lindop got it for me, its the full hks kit.

[chrisJDM]

putting figures aside, are you impressed wtih the drive? have you gone from twins to to4r?

[mattywhitt]

Yeah i am impressed, its a different world, you have to be more carefull on the corners.

[chrisJDM]

at the end of the day figures are figures, as long as you enjoy the car and are impressed with it on the road thats all the matters.  It may be that the temps it was running at on the dyno made you loose alot of power that you are getting when you drive it. :driving

yes matey, wow rw that would be kicking some HUGE ass :flamed

[mattywhitt]

Will there be a label on the turbo, showing hotside and model? Will i be able to see it from the top of the engine or will i need to be underneath?

[antnicuk]

the a/r is stamped on the cast iron bit and the aliminium bit (they will be different),  it will be on the back where your down pipe comes out so depending on your manifold you may or maynot see it.  Try a torch and a mirror.  Its cast in and will say something like 0.84 or 1.06  

A TO4E with a 0.84 hotside has made 350 rwhp at 1 bar with a modest street port on a dyno dynamics so you could have a to4r but with a 0.64 hot side from a supra or something.  I thought the guy who started lindopp used to work for pip at WGT, if so he should know his stuff.   Is your engine ported?

see the picture for help

Wow, been reading this for a little while and now I\'m seriously looking forward to the single. Didn\'t realise just how big the GT3574 is ! Its got a 82mm Comp and 74mm Turbine. How would that compare to the the TO4 turbos ??

As for the issue on the power a dyno will not always paint the whole picture especially with air temps at a high level. Are you sure that it hit that level and he let it cool back down. If you pulled the info off the commander it will only display the max level, even if it was ticking over letting other things cool down.

The engine has a streetport, the hks t04r was brand new! Yep it was 2 guys who worked for pip at wgt.
