Really pleased to this car up n running Jonathan, real credit to you

Turbo we are selling is a Hybrid that is put together as a special order.

We have sold a few of these now with good results.

p.s. many thanks for the Racing Beat sticker  :bravo_2:

All the best Clive

Thanks Clive,

Maybe shoot me an email with the specs for turbo and explain a little about how it has gone together.  If you have any data from MSP installs please share that as well, spool time, boost through the rpm rang etc. I'm weighing up a few possibilities for next season so would be very interested.

Sticker is my pleasure, you (and your business interests) have played a fair part in helping this all come together and I'm sure will continue to do so...

Always appreciated.

Looks great  :)

Did any issues crop up, and how did she feel on track?

Oil got a little hot ;)  It actually will be fine for the sprinting and hill climb that I'm going to start the season with but have also ordered a 40 row setrab cooler (it is a monster!).

Other than that mostly good, struggling with some push understeer a little at first improved things a little but not perfect:

1. We added two turn of neg camber (one turn at a time) one turn transformed the turn in two went a little too far and I felt no gain.  We are going to back that off by a turn for the next test
2.  Next time out we are going to soften the front anti-roll bar to see if that helps
3.  Could also be a worn/overheating viscous diff module, that is being rebuild this week to a 4.4 and the silicone will be repacked if needed.

Turns out a 4.7 on the little 13" wheels was going to be too much 4.4 is going to give me 145mph top end and a 1st gear that will only be used in the paddock.  For the 4.7 to work I would have to have a far more focused gearbox super long first and very close ratios.  Something to think about when we go sequential.

Diff should be back next thursday which gives me 8hrs to fit it before Abingdon...  Easy.

Even up to temp the tendency remains...

Do you run a front anti-roll bar?  Here is my hunch...  The 13B is short, I have it a long way back in the car, I may just be over controlling the front roll couple and not allowing the neg camber to work well.  One thing I might try is disconnecting the front bar and see what happens.  Also when I order up the slicks for the season I'm going to go a little wider on the front tires to try and increase the baseline balance F/R.  so will be 24/57 Rear 22/54 front or Avon equiv.

Or it could be a worn diff, but that is down in Chipping Sodbury being taken care of, so we will see.

Things is ours are quite different...mine being live axled and a narrow and front and rear on 200 section tyres...plus my engine is good 100mm further forward than yours. Im really happy with handling on track its the road that scares me...goes skittishes on bumpy roads.
plenty of rubber on these a005 about 18months old now but happy for you to try them out at Abindgon.

Yeah, it is interesting.  Mine is the same on-road, takes all you have to stay out if the scenery!

I'm running 24/57 (240) Rains or 235/45 Radial V70's Rear and 20/54 (200) Rains or 215/45 Radial V70's Front.

Would be great to give the Yoko's a go to see what changes at Abingdon...  Would be good to do that before I order sizes for the season, thanks for the kind offer.

Keep me posted on your plans for Abingdon, as always still food and lodging available for you....  Might be putting a diff in on Thursday night mind you!
