Been a while again but made some more changes to help get it to go round corners a bit better . Bought some better 2.25"
Coilovers and gone up to 600 lb springs on the rear from 450lb. Made a big difference but could go stiffer for track days . The escort rack is pretty much identical to the kitten apart from the n/s mount bracket that needs moving by a couple of inches . Coupled to the epas column it doesn't need more than 1/2 turn to catch a slide .
Rear brakes are now vented and decent pads with race fluid has cured the brake fade although the engine is still running in on base boost of 1 bar or around 300hp

Rides a lot better on the lighter wheels which are half the weight of the old compomotives .

Splashed out on a pwr cooler which has taken 5ft out of the inlet with a centre inlet 3" throttle body .
Above 3500 rpm boost is very responsive and seems to do its Job pretty well after a day at oulton last Saturday .

Had a drive down to shakespeare raceway a few weeks back and ran 11.9 121mph on low boost which was a nice surprise especially as it was my first run on cold Michelin pilots


Next big change is the rear suspension which I've never been happy with since fitting the Saab engine , its one job I'm happy to give someone else so it's going up to Martin Keenan at Mk engineering in a couple of weeks for a full independant set up shamelessly copying the kimini which I've pinched lots of ideas from along the way .

Having the fuel tank up front doesn't seem to cause any issues so its going to get a bit bigger to extend the range as I had to fill up twice at oulton .

How did you get on at Oulton, Mine swaps ends so quick in the wet its taking a bit of getting used to. It's made me a bit over cautious in the wet. The short wheelbase probably doesn't help. I only spun once though, just coming out of the first chicane as I tried to get on the power a tad to early for the up hill drag. Cheers.

Have to say mine is pretty good in the wet with 3/4 full fuel tank .

It's more than likely just me taking time to get used to it and knowing how to have it set, tyre pressure, tyres, dampers ect, but when it has swapped ends on the track its all happened pretty dam quick. Not even at speed, but probably under acceleration. Softly softly needed on the throttle I reckon.

I think we have the same track width but mine is 5" longer wheelbase . If I had less weight up front mine would be the same judging by how the Elise's were coping in the wet . As long as I'm in the right gear coming out of a corner there is enough power and revs to hold any slide until I'm straight enough to change up .

I will get it sorted. I've put a lightened flywheel on it which does make it a bit snappy and dont think that will be helping in the lower gears with the rear end traction and power delivery. Next time I have the box out I'll try the standard flywheel, it could just make all the differance along with a hundred other tweeks. The most likely cause is the fart behind the wheel, I've not done owt for years and have had a bit of a shock at how bad I seem to be, lol. Can you make ppc Blyton in March. Cheers

Big changes at the back of the car , not a job I wanted to make any guesses with so sent it up to Martin at Mk engineering for a new independant set up .




The lower frame bolts on to let the drivetrain come out from underneath .


Fully rose jointed so everything is adjustable including toe link height at the inner pickup although first check shoes a tiny amount of toe in under bump and droop after dialling out most of the negative camber at ride height



No doubt some setting up required but not having the rear end floating round underneath me will be a big improvement .

Decided to weigh the car in the brake rollers , last year is was 910kg with me (88kg ) and a bit of fuel in . Now down to 885kg so lost 25kg . 380kg front 505kg rear .

Didn't sound like much til I found a 56lb weight in the garage .
