sounds nice what sort of spool time is that tho i would be more happy with 360hp with good acceleration and spooltimes than 1000hp that takes 10 seconds to spool lol we will prob do crail from time to time but for us the thril of driving is in the scotish hills also track days wont be out of the question waht is 360rwhp in fwhp about 400?

T04E is a small framed turbo altho you can spec them up for pretty big power if u desire. It will spool up very quickly based on the one T04E I\'ve driven, not that different to the twins just more linear delivery.

Not sure of conversion to fwhp on the dynapack but I recall Johns was about 7% higher on the hub dyno over the rollers so roughly yes, about 400 at the flywheel would be a good estimate.

360 rwhp would be lovly i aint got mutch knowledge about the boost but im gona gues about 14psi of boost? prob ,milesof jsut a gues lol well thx allot u guys u have been most helpfull cant w8 till we start rebuildign this engin

In my expereince the boost on the T04E will go over 1 bar at medium revs, say from 2000-6500rpm and drop off at higher revs to around 13 psi.
T04S should maintain it to the redline.

Thats what happened to Geffs turbo when it made 430atws; was making just over a bar thru 5K but was tailing off quickly afterward :reallymad

GT35 is a very nice turbo, the 700hp spec. one.

Check this page out, this car runs 18inch tyres - see how much power it has in the videos!!!

Hi Rich,
That would be the ex Bentley turbo that Geff had on at "Rotorstock"?

What happened to Max\'s GT 35/40 on Geffs car?
On Clives we found that it kept up with the engine no problem right through the rev range.Now with more mods we shall see if that is till the case.
Did it drop off at revs on Geffs?I hear that it ran the same times with Guy driving at the pod in that form?

On Gary Goodings we got over 460 hp at the hubs at just over 1 bar with the GT 42/45.It is such a nice turbo!
We are repairing that engine as we speak.

Kind regards
Carl:)

Grrr...just typed long reply to this and then ruddy PC crashed!

Basically: GT35 not tuned - running fueled up bentley map. box dead at RS, used box in, time I got to pod it sounded like one of brians cars guy had 6 runs, 2 he managed to get thru 3 and 4 in but only cause he was granny shifting. consequently motor speed dropping too much between shifts (dunno whether no bov worsened it, not convinced) and engine/turbo was bogging down a bit. suspension mods seem to work tho, couple of low 1.6 60fts...

Offered him gt42r but needs a manifold etc and no time/money for that atm. box being rebuilt now. but nothing much gonna b done to car now due to paid work! will be interested to see how 42 spools on 20B and how quickly it runs out of huff being smaller on the turbine side than garys. i would be interested to see how the 13b goes with the 42. geffs made a bit less than 460hubs at 16psi but like u say with t04, boost was dropping off to 13psi after 5k - shame cause on the road the motor has a definite big squit of power between 6 and 8K...

Whats with clives car? engine was in a RS wasnt it? ready to be tuned soon? any time scale for senor goodings car to be back on the dyno/road?
