Can you supply me with your RWHP figures for the RR vid, thanks.

Stu you posted the pics you fool:D:rofl:

 

 

 

 

And while you at it fellas, could you let Stu know what colour his car is :rofl: ;)

I can answer that for you....its a sh1t colour, and a slow colour, and a manual!!!!!!:D :D :D ;)

Poor lads obviously confused! Stu are you going to put another TT engine in aswell to make 600BHP?:rofl:

 

Or are you going to use Mr Shrimpy's calculation methods?:dance:

Nah he cant Roy - hes got a slow manual :dance: :dance: :dance:

My final figures were 368.5 bhp, 359.3 lb/ft of torque and rwhp of 302. Car is a Jap 2+2 twin turbo,mods are listed below.......

Your car was like a hurricane adam when i was standing behind it :)

 

I know you were dissapointed with your results, especially seeing the mod list, what were you expecting and what do you think the potential of the engine is?

I've had it dynoed before at 351 at the wheels, and that was only pushing 0.77 bar...... So to be making substantially less at 1.33.... well I was a touch pissed off to say the least....

Potential wise...I dunno....its gotta be good for around 500rwhp - its just getting the b@stard thing to work!!

I think most people were disappointed with the results from that dyno - there was a massive difference when compared with others I've used. Was it just me that noticed that the numbers for allegedly 'standard' cars were going up towards the end of the day and what about the alleged 'flywheel' calculations on the auto boxes - what a joke ! I think if you're graphing the figures you should stick with the more realistic RWbhp numbers. (and remember that all you're really doing is comparing cars on a day, the actual numbers are less important)

 

Would have been interesting to see Warrens '431 rwbhp' on this dyno, I reckon it would have been nearer 360 ...

Must be the dyno giving incorrect readings......there's no way Adams car is 300bhp at the wheels! That sound like 50bhp too much :D :D ;)

 

Seriously......was there anyone at the event that went to the same RR as Warren when he achieved 431bhp? Was this figure wheels or flywheel.

 

May a % adjustment can be made to make everyone feel slightly more positive above their power output.

Thanks mate!:mad: :mad: :slap: :cry: :rolleyes: :p

Yup, me. Warren got 431, I got 312. This time I got about 260 IIRC. Big difference ! Also, not so long ago I got 287 at the other dyno SE use (T&C Engineering) in Colchester.

Andy when you got 312 your car was an auto;)

Yeah, but that should have made it worse ! LOL

Think of all the HP wasted superheating that oil ....

Just checked back to when mine was last on rollers,and not so many mods,was 420bhp@6,300 (auto),i think the figures from sunday are maybe off somewhere,still next RR will be better for all i think;)

I wasn't impressed being told that the rolling road notoriously read low. Especially seeing as I only went on to see if my car was running correctly, how did they work out the flywheel figure? was it just x+60? for manual and x+150 for auto?

 

To me on a stock engine 20rwhp is a lot, o well I'm sure there must be a reasonably priced RR out there which is accurate.

THOR Race Engineering.

Performance Car Tuning (Coventry)

 

 

THOR Race Engineering Ltd brings to Coventry and Warwickshire a professional performance car tuning workshop.

 

 

THOR provides owners of fast road or track vehicles a high level of technical skill and knowledge to enhance engine performance. Offering everything from scheduled maintenance and servicing, electronic engine control remapping, complete engine rebuilds to bespoke custom engine and chassis combinations.

 

European and Japanese manufacturers, UK specification and grey imports are all welcome. We can convert your car to UK spec (speedo, odometer etc) and get it ready for SVA or MOT testing. Servicing, maintenance and parts locating is no problem as well as a comprehensive level of tuning upgrades.

 

 

 

Our 3000ft2 premises houses advanced tuning equipment, the most fundamental being a 4 wheel drive 1600BHP chassis dynamometer. The system is able to cater for front and rear 2 wheel drive and 4 wheel drive vehicles. This is similar to a rolling road but directly couples to the vehicles wheel hubs. This means there are no problems associated with tyre/roller slip, increasing the safety and accuracy of measurement. Imagine being able to drive your car at 150MPH and jump out to analyse sensors within the engine bay. This is perfect for analysing faults only apparent when driving under load and tweaking the engine for maximum power output. Twin air fans each blow 20m3s-1 of air towards the front of the car to provide engine cooling.

 

 

 

The equipment is able to measure in real time the engine torque, air intake temperatures, turbo boost pressures and importantly the air/fuel ratio; BHP is calculated and corrected to British DIN standards.

 

 

 

THOR offers simple power runs on the chassis dynamometer to give you a detailed picture of how your engine and drive-train are performing. The unit also provides valuable assistance in the full remapping of electronic engine management and also re-jetting of carburetted systems; so even your classic sports car is catered for within our range of services.

 

The process of engine tuning often requires the fitment of new or replacement electronics. THOR staff are degree qualified in electronics and can tackle any installation and diagnosis task with professional confidence. We also specialise in reading and clearing engine management fault codes and diagnosing electrical and/or mechanical faults in UK and grey import specification vehicles.

 

THOR also have staff skilled in engine rebuilds and mechanical work, porting heads, gas flowing, lightening of cranks and exchange pistons etc.

 

THOR Race Engineering Ltd are confident to be able to help in any aspect of maintenance or tuning of your specialist vehicle.

What does the Dyno measure,

 

THOR Race Engineering Ltd have a 1600BHP (4400ft/lb) 4WD chassis dynamometer and now I'm going to explain a little more about what it can do, our services, prices and dispel a few myths.

 

The Dyno measures....

 

TORQUE at the wheel hubs,

 

Calculates the POWER at the hubs,

 

manifold PRESSURE ,

 

air inlet TEMPERATURE (depending on where you put the probe, could be air filter, intercooler, radiator etc etc)

 

AIR FUEL RATIO (or Lambda) with a Bosch LSU wideband O2 sensor.

 

You get all this in just a power run

 

 

So how is a power run performed ?

1st we select the nearest gear to a 1:1 ratio as possible.

For most manual cars the top gear is an overdrive gear and thus the previous one is normally the 1:1 drive (so 5th for a 6 speed and 3rd for a 4 speed).

For auto's it is normal to hold them in Drive "D". On the Toyota Supra, for example, it's easy as we can use the Manual mode to hold the gears. Most other makes of auto are difficult and power runs are hard to perform as they keep changing gear.

 

We then take a steady state control run at 2000rpm to synchronise the Dyno RPM to the car RPM. i.e. work out the rear differential gear ratio if it's unknown. Normally somewhere between 3.8 and 4.2 for most cars.

 

We can make a power run over any RPM range we like. Normally the run starts at 2000rpm and ends at the beginning of the RPM red line or 500rpm before. 7000rpm for example. THOR staff members always ask the owner first if they have a preference.

 

The power run is a controlled power run and if the equipment has 4000rpm set to be the maximum RPM for the run no matter what anyone does it will NOT go above that.

So if you aren't happy to hit the rev limiter (which we prefer not to) then we can set this 500rpm below.

Most cars have already reached their max power before rev limiter anyway.

 

We NEVER give you a printout for Flywheel power and ALWAYS give a figure at the wheels.

That way you CAN compare a manual car with an auto one.

 

If people ask we always use the stock answer of 20% and explain we are not prepared to argue about flywheel power as different cars have different transmission losses.

 

 

Any questions please contact us.

I think it was about 260, but I'll have to check the chart. It should probably be very similar to whoever was a couple of bhp behind me with 325.

Well I had 253 RWHP but managed to get that calculated to 334 at the fly
