Given that your car is practically doing that on a 75mm pulley logic would state yes. But how reliable would it be? Personally I wouldn't go there myself!

Mark@Abbey M/S 235 Report post Posted May 18, 2015 Jay as your car has the under drive pullies fitted( crank pulley) your car is on the maximum rpm for the Sprintex 210 SC I am afraid Share this post Link to post Share on other sites
CHOSENMAN007 81 Report post Posted May 18, 2015 I see. So would fitting a stock crank pulley again let me exceed 1 bar of boost? If not I certainly need to look at another avenues for a slight bump in bhp. Share this post Link to post Share on other sites

Lauren 2259 Report post Posted May 18, 2015 Must admit, 245 seems a bit wide for an 8.5" rim. Toe seems alright, I really need to find out exactly what my rear toe is. That's very little toe in at the rear. How does it affect rear stability? I'm guessing it changes direction well enough. Reckon 2 deg neg camber on the front is worth doing. I run this with 1.75 neg on the rear. Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted May 18, 2015 the 245 doesnt look to big for the 8.5 front rim. I was more talking about the profile , think a 35 profile would look better tbh , car looks a little heavy on the front end I feel. With the tyre width I am running it will have enough grip so running very little toe in helps the car I feel , I havent had a good drive to get a real good feedback yet but I do know it need a little more front travel so I will need to lose some droop to gain so travel but this might help with weight transfer. Running 2 deg front will make the car nervous I feel in the straight ahead position but maybe I will need to dial this amount of camber into to try to be 100% sure. All good fun thou the HKS Hipermax 4 Damper do feel very very good so far. Share this post Link to post Share on other sites

No doubting a twin screw super charger has the best noise out of any forced induction set up in my opinion. I to was doing loads of homework on a 335 blower. But for now I will wait it out. The likes of a harrop is one to watch. I can only push so much as don't want to blow my transmission like Keith has. Will work on handling. But the abbey demo car is the place I'd like things to go in the next power jump. Should wack in proper headers and see what happens. My decat stock headers set up might be holding it back slightly.

James - I didn't 'blow' the transmission, I cooked it.... overheated with some overexuberant, overrevving trackday driving.. the matter is being resolved. Smudge, you are right in thinking forged engine bits if you want to retain reliability over 1bar boost. The GPRM Avon car is running 2.2bar boost with forged pistons/rods. And a standard crank....

Mark@Abbey M/S 235 Report post Posted May 19, 2015 K , saying to run over 1 bar you need uprated engine parts isnt quiet true. The limiting factory of the FA20 motor is cylinder pressure which hurts the stock con rods. Turbo F/I makes a lot of cylinder pressure in the mid range area where as a SC car makes less cylinder pressure in the mid range area ( The centrifugal charger makes less than a positive displacement charger) The stock crank is pretty strong and as long as the lubrication system is good I am sure this item will be okay for 500bhp. The GPRM motor runs dry sump so we know the lubrication will be good. 1 CHOSENMAN007 reacted to this Share this post Link to post Share on other sites
Lauren 2259 Report post Posted May 19, 2015 Mark, running 2 deg neg camber on the front feels fine. I don't know if your very wide tyres will be more of an issue, but I have no issue at all with that amount of camber and I do some mileage as you know.

Deacon 1357 Report post Posted May 19, 2015 I have -2.5 degrees camber at the front and -2 at the rear. That also feels fine and I've done lots of local and long distance drives with it like that. Share this post Link to post Share on other sites
