.... from what i gather though the 1500 and 1700 8v is fairly even as long as you rev the 1500 upto 8000 rpm(ensure the cam timing is 100% spot on) only losing about 5-8bhp to the 1700 8v..... Do you know what sort of power you are actually running?
I think you may find that the faster times are due to the car as well as yourself. The 33 is amazing as a race car, plus the longer will base will be an advantage over the Fiat, i think thats why neil put emma in the 33 and not the fiat.
People have different perceptions on the handling of a 33 and i think it just depends on what you prefer. I tried a set up at rockingham during testing which was rather over steery but i got round in 1 min 39. which was 2 seconds under the lap record! i then set up the car differently for brands to be more neutral as with the oversteer i went off in testing and couldnt get under 59seconds. so once we changed the settings to be more neutral, after lunch in my first few laps i did 58.3 I kept this same setting for the rockingham race where i dont think i got under 1 min 41 because the car just wouldnt turn in as it was to understeery for that track.
Are you running a bias valve as that helps with moving the rear end around especially under breaking to get the turn in but the car behaves once in the corner with the neutral settings i run.
Change from the yokahamas to toyos and then you can run in what you are now or the alfas with no worries. I think also should it help in any way i think bianco may have a few varients of the boxer engine from 1500 to 1700 8v either full race preped or road preped.
the 33 is supposed to be delivering about 115 Bhp but that figure comes from Roger's memory and was from when it was last rolling roaded, about 4 years ago, after a rebuild. The car has not had that much use since but who knows whether that figure is accurate or not! I only rev it to about 7500 as Roger told me that it tended to have piston Vs valve moments above that! I am assuming that the 1700 8v in ARCA Class D spec would be about 120-125 Bhp but would benefit from a fair bit more torque?
This particular 33 and my Fiat both handle very well, and surprisingly similarly. The Uno grips and goes but has a lively rear end and seems to put its power down very well, it really is very agile but I haven't spun it...yet. The 33 can be similarly lively at the rear (depending on rear tyre pressures - it was very oversteery when I first got it and both my driving partner and I spun it at the Bomb Hole!) but doesn't quite have the traction of the Uno and is a bit slower to turn in now that I have dropped the rear tyre pressures. The Uno is supposed to have had 118 Bhp when I got it (so very similar to the 33) but I would expect the Uno to be a bit lighter. When the new 1580cc engine eventually sees the light of day in the Uno it is supposed to have about 130 Bhp so ultimately should be a bit quicker than the 33! Maybe!
The 33 does have a brake bias valve and I have gradually moved that more to the front in the drier races but the brakes don't inspire confidence - they seem a bit spongy to me - although do still stop!
I think that if I keep the 33 the next set of tyres will be Toyos so that I can have the choice of running in Tin Tops or ARCA Class D and I am considering ringing Bianco to ask how much it would be to fit an 1700 8V (I am assuming that it is a straight swap?). The gearbox needs a rebuild, too (2nd gear synchro seems to have gone) and whilst the engine and gearbox are out it would be worth respraying....arghh, the expense!! It might still have to be sold because, as is, its not really worth me having two cars that are eligible for the same class in "Tin Tops".
Next (and final) race of 2008 is on sunday 19 Oct at Snetterton. Mght be in the Fiat Uno, might be in the 33, who knows!
