Lees car is very controlable on the throttle.
Ok heres the long awaited graphs .
These are flywheel figures with DIN70020 correction applied, based on actual data from ecu into RR software. The right foot was feathered in at around 4-5000 rpm to prevent wheel spin. So in reality will be even better in this area than shown.
This run was done in 5th gear.
ps.The graph has not been 'smoothed' out ; which Superchips can do on request..this is the raw plot.
Drivetrain losses (measured) are 15% (58bhp).
Higher than some for 2 reasons.
1) We had to use 5th gear due to the high power spinning the tyres on the rollers all day......makes a noticable difference.
2) The Maha RR software applys more load (variable to achieve a constant rate of acceleration of the rollers) therefore increasing tyre drag.
Therefore on another type RR you may see more WHP.

looking in evo this morning, see what makes more than 300 bhp per ton
not much from germany, a bit of italian and a few supercars, you will be suprised at the big names delivering less

Hi Alan, yes unfortunatly everything is heavy these days (safety etc). An eighties hot hatch weighed 850kg ..modern hatch 1200+kg.
Lees power is all your ever going to need, some may argue too much for the road, but picture this.:-
Youve had a stressful day at work ,your driving home in rush hour traffic, you eventually get on the open road, theres just 3 cars in front (probably a Yaris estate ,I cant even look at the back end of one on those)...your in third you do one straight line blast past all 3 tearing you into the back of the seat for a few seconds ,you return back to normal mode.....and your day has suddenly become worthwhile. Life is ok afterall, and tommorow youve got something to look forward to aswell.
You dont need it but you want it

All that extra power would be nice to have in a daily driver.

i know this will only be a guess
what sort of power would you expect to produce from a 300t with only a std or jcw, stage one head?
would you anticipate any other issues using a less developed head than on yours and lees car

Hi Alan, we fully expect power with stock head to be in excess of 300bhp. Either that or our stage 4 head + shrick adds 90bhp! (which is unlikely). Being a turbo to an extent we can control power by increasing or decreasing boost . So if your making too much power we can trim it back aswell Im going to put full final spec GTT300 and GTT350 spec thread up in a minute. -Check it out.

Also dont confuse corrected power with 'WHP with measured losses added on'......its a .completly different thing.
Also single roller RR's (dynojet) with give a noticably higher WHP figure than the twin roller type we have over here..
Oh power (& torque), you'll have to wait until tommorow.....What do you think?
Boost was 21psi BTW, no fudging, no icepacks on intercoolers (yes you!), no race fuel, (Tesco 99), no high tyre pressures.......I did try that but much toooo much power for that one.
GRAPHS ADDED>>>SEE POST 76

the reason dynojets typically read higher is not becuase they are single roller dynos... it's be cuase htey are inertia dynos... they have no resistance say like the mustang dynos which have eddy currents to ad proper load to the wheels of the car...

Also, dynoing in 5th is pretty nutty.... the #s tend to get skewed... ussually running much higher.... 4th is as close to a 1:1 ratio you can get... I understand your wheels were spinning, so yeah... you do what you gotta I guess...

nice numbers... have you taken the car down the strip yet?

Hi Tuls, yes the dyno jet type spins up quicker, what Im refering to is the losses figure (if measured) tends to be a fair bit less on the dynojet inertia system. Single roller will produce less drag through the tyres (one squashing point against two). We had to use 5th & 6th no choice, believe or not this thing spins in 4th on the road (r888 tyres too!)No plans to drag it, too much risk in trashing the clutch/driveshafts/diff/gearbox/flywheel for my liking & too dependant on driver/tyres/susp setup etc to get comparisons of engine performance. However we have done and posted a few acceleration times already. I will do a 30-130mph sometime aswell ..probably in my car this time.

Yeah I follow you on that.... There was acually one like that in Scottsdale, AZ imported from Aus.. what I meant was some dynos like the MUSTANG DYNOS now have the ability to load the car... you can actually floor the car and the dyno will hold it at whatever you tell it... pretty neat...

I think the only diff is the rollers have "tred" so you don't get as much slipping... the only time I have ever seen the slipping problems was over 1200 BHP... but there were always young guys around egar to sit in the back of the car... ha ha!

I understand how it is with the tire spin... believe me!

I am curious to see what the 30-130 times are... good luck!
