So I finaly managed to try the SS1 out for the first time in anger, at the Ty Croes Sprint on Anglesey.

The car is 42 horses short of the Sabre Ti that I used at the same event last year, so beating those times on scratch was unlikely, but I had a bloody good go at it :lol: . The car feels better planted and more controlable than the Sabre, and it stops better too. Better in fact than any small sports I've owned. So I can confirm that the Wilwood/Mazda/Big MC/22mm Slave/Single line conversion works an absolute treat.

Due to handicap factoring in the Classic Marques Championship, I'd decided to run on a 1A tyre (Uniroyal Rainsport 3) although I did bring a set of 1B R888 SG along in the same size. We run two different tracks over the weekend. The Saturday is a double lap of the short circuit and is quite technical, with a couple of hairpins, long straights, long uphill right hander, unsighted left hander and down hill off camber left hander that's quite character building if you get it a bit wrong. The Sunday is a single lap consisting of the same section as Saturday, but adds the very fast section of the International circuit, allowing speeds IRO 110-120mph in a warmed over Ti. It could be argued that if you're going to run a 1B tyre, the Saturday would be the day to do it, but the rules don't allow for a switch back to 1A without a heavy 2.5% penalty on your time, so I committed to using the 1A on Saturday, hoping to get a free run on 1B once the three timed runs (counted in CM) had been completed. Unfortunately we only got three timed runs, and I found out that we weren't getting a 4th once I'd changed two of the wheels over in the garage :evil: . So I left the car like that over night, hoping for some inspiration as to whether to try 1Bs on Sunday.
After crunching the numbers on the spreadsheet, I found that I'd need about 3 seconds more out the B's to break even and it would be doubtfull that I'd actually gain an advantage in the CM championship. However, we're also running our own SSSC in parallel and the penalty there is 1.25%, so I could make that work :D ........ I think :lol: . I was also contemplating why I do this sprinting thing in the first place, and it's because I love going as fast as I possibly can, and without any doubt the way to do this was with a 1B tyre. Decision made ! Sunday was to be B day (not a device to wash your ar53 in BTW).

So how did I do, compared to last year's event in the Sabre ?

Sabre stats - 199 BHP 960KG 1B Tyres
SS1 Ti Stats - 156.8 BHP 920KG 1A tyres Saturday 1B Tyres Sunday

Saturday:-
Sabre 133.65 seconds scratch 125.58 seconds on SSSC handicap
SS1 Ti 136.9 Seconds scratch 124.70 seconds on SSSC handicap

That's 3.25 seconds loss from previous scratch time (but on 1A tyres Vs 1B last time out in the Sabre) and a gain of 0.88 seconds on handicap.

Sunday:-
Sabre 106.67 seconds scratch 100.23 seconds on SSSC handicap
SS1 Ti 108.07 seconds scratch 99.79 seconds on SSSC hasndicap

That's a 1.4 seconds loss from previous scratch time (The 1B effect brings it ever closer) and a gain of 0.44 seconds on handicap.

It was quite a consistant performace too.

Saturday's times:- 137.61 137.71 136.9
Sunday's times:- 108.07 108.69 108.17 108.94 (with pirouet and trip over the grass at the finish line :oops: )

I think I need more power to get the most out of the B's to make them earn their keep on handicap. But the grip difference is worth the penalty, they're so much more fun to drive on.

So all things considered, I'm really happy with the car. I don't think it did too badly for it's very first event ever, especially after a complete strip down and rebuild. It only conked out once, just after I crossed the finish line, but I think that was fuel starvation, as a full tank sorted that issue for the next run.

Development wise, it won't get anything before Harewood at the beginning of June. But if I can find the time, it may get the engine I'm currently building and a Mk2 gearbox with quick shifter before the end of the season. It'll mean yet another trip to the rolling road, but hopefully it'll be a much better result than the last trip.

So, a couple of thoughts on development. The spare engine I’m building up may get a Cometic gasket (still debating this with myself), but I’m also thinking about a top mounted turbo (T25) and mappable ECU, adjustable fuel regulator etc.

A couple of questions. Does anyone have a top mount manifold that they may wish to sell or lend me so I can get it copied? Or drawings?

What is the easiest route to a mappable ECU, which brand is best, and what parts would I need?

I’d like to achieve a fairly bullet proof 200-220bhp.

Jamie at Revlimit would be able to map your existing ECU I would think Steve.

Pretty sure you can’t do that with the ET ECU Steve.

Right. That's a shame if you can't.

I've not got a manifold, but I have a turbo that may be of use, I'll dig out the spec / details.

Cheers Ben. Not looking to go too big. Just a mild upgrade on the T2.

No one ever produced ET tubular manifolds officially. I made one for Batmobile and I imported 1 x made from steam pipe along with some Canadian CA20 inlet manifolds from Canada. The exhaust manifold was for Wacomuk (Desh on FB with the soon to be finished Sabre turbo).

Very little done on the car. But yesterday I added 5mm spacers all round, which means the new wheels now stick out as far as the old ones. And I changed the rear ARB droplinks for better quality alloy ones. The MOT guy had remarked that the ones I had fitted were a bit loose. They’d only been in the car a couple of months :shock:

Were those a direct fit Corky or did they need modding?
