161bhp @ flywheel with a stage 2+ equivalent?

[jules_s]

Chris, Am I right in saying your TMS graph shows you getting more lb/ft of torque than bhp too?

Thats what I was making

[SteveM]

My Regal RR figures showed 158bhp & 166 lb/ft

The Komo-tec passes a huge volumes of air through so I reckon this is giving me some added gains. I've had to ramp back the MAP values to the ECU because the addition of the Komotec had me running too rich!

Torque looks to be 152/153 lbft from that graph

[jules_s]

Torque looks to be 152/153 lbft from that graph

Looks about the same in BOTH graphs....

[Its Will]

My graph is pretty much the same as Christurbo's. Could be that the car has 43k on it so is getting nice and easy now. Who said slack? stop that at once.

For reference my 2.2 got 167bhp @ Courtenay with Scorpion Exhaust, 100 Cell race cat, ITG and their remap.

Come on Cheeky I can see you lurking. I'm sure your'e dying to say what yours did today

Mine was a relatively similar 169bhp at Courtenay with the Hayward & Scott, ITG and remap

FFS. Hasn't anybody read JT's post on the TMS website? RR's owners are renowned for 'bending' the results to sell their tuning packages......IMO thats exactly what the object of an excercise like today was meant to clear up. And yet we still get people posting 'my car made 999bhp at xyz tuners' on a thread specifically relating to the TMS day today.

[cheeky_chops]

well my vxr last showed 248bhp @ fly on AMS's rollers last feb since then i have had a full zorst put on, todays figures - Spec - vxr amd stage 2, blueflame 100cell 70mm system. 255bhp @fly 215bhp @wheels I think there were some dissapointed people today - I saw a stage 1 vxt with 166bhp @ wheels!

[TheStoat]

Well I can't remember the torque figures and can't be arsed to get the printouts from the car now I do remember that the BHP came out at 177.9 and 212.9 for the wheels and estimated flywheel respectively. That's a Turbot with a BlueFlame system, Stage 2 map and a dicky primary o2 sensor. The car feels slightly less bonkers than when it was originally remapped but hopefully the proper feedback from a working sensor will allow full power again. I'm very happy with the smoothness of the mapping I was pleased to find no alarming troughs in the power curve like some guys with Turbos. I'm really pleased with how the remap smoothed out the throttle response and the graphs show a nice progressive set of curves to back up the feel of the car. It was a good day John so cheers for that Andy Edited to say: Did Paul's Astra VXR Turbo'd beastie get dyno'd for a comparison? I think at least one chap is booked in for a new turbo after the graphs revealed a flaw and he's going for the Astra blower as it's apparently much superior...

I'd be interested to hear someone like Courtenay's opinion on this. Given that they provide a before and after graph, the only way this could be true is if they deliberately fiddle the before or after figures.
Yes we know that some tuners rolling roads have been known to over-read, but given that in most cases we see a before graph which is relatively close to the claimed output (+/- 3 or bhp), either their claims are legitimate or they're on the fiddle

Anyway, as someone else said, the figures don't tell the whole story. Even if mine isn't any quicker than a standard NA (and given the way it pulls at the top end, I'd be surprised if it wasn't), it still feels subjectively quicker and more responsive, and that's what should really matter.

Totally agree Jim,

Having re-read my post it comes across as a tad over agressive I guess.

It just pisses me off that every time we get an opportunity to sort these things out we get counter productive results from other tuners.

From what I read this morning JT was alluding that the headline bhp results of a standard engine were taken in lab conditions, and that was why the results from today would be lower than expected.

Either way, im absolutely convinced that my 2+ is a vast improvement over standard. if that means im getting 145bhp/same torque when the standard is in fact nearer 135 (as opposed to the book) then I can understand that

[Joe-Turbo]

although i had my own dissapointment on the rolling road . after going for a spin with one of the techies in his car (remap/vxr turbo/milltec) I was VERY impressed with the improvment over standard/stage 1 . roll on the end of june (booked in with tms)

[TheStoat]

To be honest I don't think people will be put off as far as VXs go. It only takes a quick run in a remapped car to demonstrate the difference in drivability compared to a standard chariot. That alone shows prospective customers what they can look forward to without a graph in sight...
