I See a few followers from the thread on the engne "what engine for 500BHP".

As for the Toyota box it is still untested as I am stuck at work for the next couple of weeks, but once home & I have cleaned out the oil from the water system & fixed the oil cooler, then it should be back on the road, and testing of the box can begin.

It also needs to go back to AET for a couple of tweaks to the mapping, not for more power, just to sort out some transient fueling, that didnt show as a problem until the car was on the road. The 475BHP at the wheels (525Flywheel) should be enough for now.

When I went for mapping I specified about 500BHP at 1.2-1.3 bar, so they set the boost at 1.25 and the car made 460 at the wheels on the first power run! If I wanted - more is possible!

There are some more pictures on my site www.turbonutter.net

here are a few of the interior...






And the engine



I hope to get the car on a track or two this year, but it wont be going rallying - I aint risking that! But if all goes well this year, then later in the year or next year I will try to do some sprints or hill climbs in it...

For now the only video of the car being driven is this one made by PPC for the magazine..

A couple more photos.....

Thanks for all of the +ve comments on the car and the build.

Dont forget to thank my wife and family as well, for allowing me the time in the garage to complete the task! Without their support it wouldnt have happened...

The wheels will always be an issue for some, as I said this car is in no way attempting to be a replica, if t were then it would have had coffin spoke wheels. I have intentionally done things like the wheels / duct in the bonnet / engine etc so that it is obviously not a replica, sure the body is a copy, but I am not trying to fool anyone into thinking its origional.

Power wise you need to have some respect for the go pedal, its a stratos, so easy to spin, but drive it sensibly and the power is useable. Straight line, once its moving, it dosent spin up the rears, so traction is pretty dam good. Of course if it rains its a whole different story, but thats partly don to the Toyo 888's.

I hope to get some more video soon & I got an in car video camera for xmas, so that should provide some interesting footage.

[turbonutter]

As for The TOP GEAR Episode with the stratos, that topic is best left untouched, suffice to say it was setup to fail, to make good TV.... and no the stig wont be getting anywhere near my car!

One final photo before I loose my internet connection for the next week.....

Tremendous!



What inspired the paintwork?

The paint work is based on one of the color schemes the stratos was seen in when rallying - namely the olio fiat one. The lettering has be changed to Incorporate my Initials & the Kit, it being a "corse"



I also changed the wheel colour as I hate white wheels

Congrats on building another. Must have been hard after the last got destroyed by fire.

Awesome car!

It took 10 years for me togo with the second one, but I cheated slightly by buying a finished one, during the rebuild I ended up doing far more than I had planned, so it would have been as easy to start from scratch. The big advantage of having a registered car is that i didnt need to worry about radiuses etc for the SVA...





for example the panel catches on the side of the car & spring clips on the lamp cover... not sure they would pass....

[turbonutter]

So its back on the road, minus the oil cooler & I got a quick video. have some issues with the video, so this is all I managed. Also I had to stop playing as the oil got a bit hot....

Build me one, how much?

If you wanted one built for you to this spec it wouldnt be cheap..... I doubt there would be much change out of 100K

Christ, u can see how much it moves around under load, short wheelbase at work there.

Reminds me of the Mk1.6...x100!

Wild is the best word I think.

It does move quite a bit, with it being short, the rear wants to overtake the front.... In the start of the video, the wheels are spinning which dosent help, but it dosent stop squirming even when they grip...
It does remind me that i must get the suspension set up once the mapping is sorted.

Maybe if I have a good year

You could always build one yourself - its much more satisfying!

I've just realised you got to into 5th on that video!

That's a lot of speed in not a lot of time.

Oosht.

The 4-5th change is around 130 & that was probably a lift at 145........

totaly fake

[turbonutter]

Picked the car up from AET Motorsport earlier this week. New Crank Sensor has fixed the problems I was having. I witnessed it on the Dyno while I was there and the power is now up from 475WHP to 492WHP and at less boost - thanks to some tweaking of the map

Great build. You,sir, are a legend.
How do you find the pwr charge cooler? Have you used it for long-ish times? Does it keep eficiency high?
And last, where did you buy?
Despite not a huge market i seem to find a lot of chinese fakes. And not many reviewsfromactual owner of barrell cc....
Thanks

The charge cooler seems to perform well. At least it did during the mapping where they had no issues with the inlet temps even when making repaeated power runs. As for on the road or track with extended use, so far the car has only been driven on road, so I cant really give the cooler a hard time. I plan to do a track day at the end of the month, so will be able to report back more after that.
I bought direct from http://www.pwreurope.com/, they also designed and supplied the Pre Radiator for the system, which is just as important & recommended the pump flow rate and pipe sizes..

If you have a front engined car, then use an air to air intercooler, as it will always give a better efficiency (apart from the initial start from stationary)

gianlu said:

Thanks i'll check with pwr...
Mine is rear engine, hence no air/air, unfortunately. I do have one but with latest rebuild and going closer to 400bhp that air to air is not going to work well!

I dealt with a guy called Andrew Parker who was verry helpfull. To make things easy to assess, I took my car there before I fitted the turbo and let them have a look so they could advise on what i needed.
The biggest problem is where to put the radiator at the front & how to get the pipes to it (25mm diameter)

Mine is lotus exige with forged audi engine and bigger IHI turbo. I know where to pass the the pipes, and there is enough space for the cc on top of the engine. There are already some (well, one) bespoke system, but once vat is factored in it gets close to 2k.

Can you disclose how much the pwr kit did set you back?

thanks

Its no big secret
The 6x10 barrel cooler was £590
The pwr designed one off pre rad was £756
I use a davis craig ewp 115 which was £180
Then had a swirl pot made £80

Then on top of that I made my own pipes and probably 16 or so silicon elbows
So that would be close to 2k......

Spent the last couple of weeks trying to Identify a missfire above 5000rpm, finally found it friday night - the cam belt had jumped 2 teeth!!!!
That was just in time for a track day at Blyton today...

A couple of photos, I will try to get some video footage edited soon.....

Video from Blyton.

Early in the day while i was getting used to teh car/track.
