I need to do some videos, this one is from last month when it was running around 1.7 bar on a test track of course. Its 3rd and 4rth gear pull lifting off just after changing into 5th, was around 155mph.

The supra chassis does seem to be able to handle high power and torque very well. I have some bits on the car that strengthen the chassis as well. With the solid diff mount I have, you can feel the car twist as the power comes in because the diff has no movement. This is most noticable in 3rd gear as 1st and 2nd has some wheel spin but third just bites and grips. 4th and 5th are not so bad and you just get loads of thrust. Traction is surprisingly good.

Thanks, really appreciated.

I have got 2 step but find it hard to build boost on the line, it tends to bog down a bit. I think nos is the only way to do it but not sure if I want to go down that route. Jamie suggested line lock, get the tyres really hot and launch from a higher RPM.

Already got the wheels, just need the tyres. Cheers The problem is going to be the lag on the line but it certainly has the power now. I would be happy with a low 11. Its more of a top end car really, looking forward to the thunder road if I can get in. Try and break the magic 200 mph

Yes that should show the difference, even if I cant get it off the line the terminals should be improved.

Here is a bit of info on the Rototest dyno used: "Rototest is the only hub mounted chassis dyno that actually measures torque as opposed to calculating (or estimating) the figures. For this reason, the Rototest is also the only hub mounted dyno that can be accurately and regularly calibrated. Rototest actually invented the hub mounted dyno system and held the patent for this design. Being directly bolted to the wheel hubs, all issues, difficulties and inaccuracies associated with the suspension camber and toe calibration, tyre slip and carcass deformation, changes in temperature/pressure and the danger of explosion etc are all completely eradicated. There is also an important consideration concerning the potential for undetected tyre damage caused by rolling roads. These are the reasons why we do not use a “rolling road” The Rototest dyno has superior control over any other type of dyno that we have seen. Not only is it able to vary the load by extremely small increments and ramp rates, it can also hold the vehicle at a predetermined rpm set by the operator regardless of throttle position. This allows the operator to have total control of the engine which means that we are able to accurately map and tune cars to the degree that no other chassis dyno allows. Both steady state and constant load testing can be accomplished with confidence, and the results can be corrected to any universally accepted scientific standard. The Rototest Data Acquisition Centre is without doubt one of the most sophisticated and comprehensive scientific quality monitoring systems available anywhere. This allows us to monitor and capture data in real time and record all of the crucial information flowing from the engine, which ultimately provides confidence in our ability to deliver the expected outcome of an accurately calibrated engine. "

Thanks guys. I know what you saying about hub dynos, thor's was bad for that as the dyno graphs you got from them said flywheel hp although they said it was at the hubs. The good thing about this dyno is it can be calibrated with weights, they have a long bar with a weight on the end which allows them to get it spot on. The problem with a rolling road is there is always going to be a bit slip with the tryes and with big horsepower you just cant get an accurate reading.

Yes it is, I had the Veilside spoiler before. The abflug looks much nicer.

No, it was already built for it just needed winding up. Ryan living up to his company name, 2bartuning!

More boost and more timing. We also couldnt get a clean run at SRR as the R888 were spinning on the dyno, even on the 824 run.

oops sorry, added it to the dyno graph on the previous page.

SRD car on the dyno at TDI Was a great result Big thanks to Ryan for working his magic. 825.3hp at 7680 627.4lb-ft at 5580 Sam at TDI said that it equated to over 1000hp at the fly but that was going by his experience as there is know way of knowing exactly. All flywheel figures are a guess that the computer gives you. If we work with 15% its just shy of 970hp which is amazing and more than I had hoped for. Here are the details: So how does it drive on the road? Well, amazing. Although it feels like the torque is trying to flip the car over in third gear the car is well planted and grips very well. The only issues I had on the way home was the damp roads, in the dry its perfect. It feels like your being catapulted forward but its all very smooth and linear and very controllable I love it.

Just uploaded a video of the last 2 pulls.

Yep, will be there. Dam my maths! Will post a vid of the last run in a minute.

I was running Shell V Power with some Xylene mixed in to raise the octane a bit.

Thanks for all the nice comments guys, feel like the car is finally finished now. Thats some dyno the guys have there, around £250,000 worth. Really nice bit of kit and makes it much easier to work with. We raised the boost to around 1.9, I think it peaked at 2.0bar and dropped slightly. Also put some timing in as well I think it was around 2 deg.

Those rear arches look much better mate. Loose the headlamp covers and its done.

Will have to see how it goes. I am going to try and blow it up so I have an excuse for one of those stroker thingys you have Its easy to get the bug and want more, all I ever wanted from mine is to know that I took it as far as it would go.

After next thursday you may need to aim higher

Some more goodies. TRD Diff is all fitted up ready to go in the car tomorrow. Parts for the engine build. CP Pistons BC Rods Fully built head with GSC cams Shimless Buckets

Hi and

HKS 264 cam clearence is 0.2mm intake and 0.3mm exhaust.

Cant hear it as I am at work with no sound but if its a rattling sound it may be one of the valves on the sequential system as your running in TTC.

Awsome build this Eric, well done
