As above....
A collegue ran on a RR Shoot-out this weekend and got some very strange/poor results (not alot mre then standard).
Just wanna have a look to see what they should of been with a TEK2.5 and full decat.

If the RR plot shows boost as well then even better.

 

you could try sticking a post in the scotland forum to see if anyone has some star/tek2.5 results.

iirc quite a few scottish guys have run them at r/r days and I think they usually get slightly higher results than similar cars with PPP but the curves are fatter.

 

My Tek 2 on a MY99 RB5 full de-cat on a rather iffy day when it wouldn't boost

 

P.S This isn't a dig at the TEK2.5 map as the owner is chuffed to bits with it and how it really pulls through the gears.

However a recent RR day shoot-out begs to differ - But it wasn't the only strange result of the day.

John..... If your readin this the check out the plots below


Aug'02 Tuning Japanese Plot
TEK1, Decat Center, TSL Grp'N' Rear


Nov'03 Tuning Japanese Plot
TEK2.5, TSL Grp'A' Decat DP, Decat Center, TSL Grp'N' Rear


Check out the Poor Boost plot and how it tails of on the latest plot. This could be a large factor on why the figure was so low.

I would expect this car to be at least 270BHP, especially as the TEK1 with Catted DP was knocking on 250BHP.

Funny looking plot. RB5 Black's at Star is also funny, note the boost profile and the torque, but the power is about right on these rollers - decat MY00 usually does 218-221 BHP. On the road his car will probably (it was when I set it up) be reaching 1.2 bar at about 3000 RPM depending on gear, and then sloping off from 5000 RPM and gently sloping off to 1 bar at 6000 RPM. On the dyno plot it is limited by maximum duty cycle. If I had put enough duty cycle in to let it reach 1.2 bar on these rollers and make a more realistic torque figure on the rollers at 4000 RPM then it would overboost silly on the road. These plots illustrate the obvious that you just can't map boost control on rolling roads, well not this sort of boost control anyway. A Dawes would be more consistent but still read about 0.1 bar lower on the rollers.

Back to the Tek 2.5 plot posted by Scott.T, it is odd that the torque follows the boost by such a large RPM lag - drive it and tell me it does that on the road - it looks like a far bigger turbo from that plot. Interestingly the boost curve is not that far off on this plot, don't know what to say about the figures, suppose you have to compare them with others on the day. I gather there were a lot of disappointed people. There is no telling whose rollers are right, but 270 BHP from that not a icecube in hell's chance I am afraid based on the other results I saw from a brief look.

John,

On the road this car hits easily over 1.1BAR, recorded on the DEFI's and has also been seen to run approx 16.9psi with a select monitor attached.

Mods on the car are as stated above the plot. Turbo is a boggo TD04.
