Yeah, for transmission life you'd be better off with the more progressive delivery of a turbo - or just being gentle with the application of your right foot. Either way, more boost needed if you want to make big numbers!  ;)

My old psd eaton'd g40 was quoted by Steve pitt to be running 220bhp ATFW. It was savage and was fighting for traction whilst trying to put you into the nearest ditch :-)

Did you have an LSD on that Ben?
Mine with the 8P on atm is pretty undriveable in 1,2,3 when you plant the right foot.

Very impressive nick. Personally I'd be happy with that. I mean how fast do you want it lol. It looks the tits, has good power. I'd get the handling sweet as and then your gonna have a nice useable car that's stupid quick but not insane. I know your a g lader man too so unless you wanna possibly go other routes I'd say what you gots great and your not pushing the engine to it's limits too if there's great potential as hayesey says and you stay well below that.  Surely a well set up chassis and circa 180 bhp is gonna a right enjoyable toy? Just my thoughts... But then the abilty to say 'i've got X amount of power :-P' is always appealing.

Tony's was overbored to 77mm and had a Sorg 1.4 stroker crank, sold as a '1.5' conversion, he also had Jenvy throttle bodies ready to go on, I've not emailed him for years though...

G60 blower is the only way to go for decent power, the G40 blower can't flow enough.

A promising base line anyway  :)

Like spaniel says unless you crave the 200 bhp figures then 180bhp in a car weighing 800ish kgs is spot on. You then just need to solve the age old handling of the polo and you have a weapon in your hands. My 1st g had just twin v's 65mm pulley and chip.  That felt rapid!!! There must come a point when you start to sacrifice reliability for power. My eaton'd one started running rich and destroying spark plugs.

Tidy result that Nick,

Fairly sure we're running an identical spec right? Even built by the same people I believe?

Would be nice to compare notes and try work out where you've found 10bhp+ on me, albeit torque roughly the same. Mine reads 7psi on the gauge but would suspect that's more gauge error than a genuine difference.

Yours will always have the edge anyway, mk2 1.5 is waaaay cool!

G60 for me too this year hopefully...

That torque curve is amazing, I bet you could set off in top gear.

Such a nice car too, really looks great, I can say for sure its the best polo I have ever seen.

What clutch do you have Nick?

I have a paddle friction plate that someone off here (cant remember who now lol) very kindly donated. And fantastic though it is, its terrible in traffic and setting off. Apparently its from CG motorsport at was made to take 200 lbs/ft, which I can confirm it does with ease now lol. Im just a bit sick of the juddering and crap.

I take it you have somthing a little more civilised?

So what spec are you running then fellas? Have either of you listed it on the forum? I like the thought of 180bhp!

Helix do an organic-lined clutch. It's fine in Robin's 194bhp K03'd G40, and several others have used it - including Barney's old uber-spec 195hp G40. It stood up to the instant torque hit from Barney's car, should have an easier life with the more progressive boost of a turbo. When I drove Robin's car you'd not know it wasn't a stock clutch.

Sounds good, I can get a standard friction plate organic lined for £20, then possibly just recess the pressure plate into the flywheel to get a bit more clamping force. I just wasnt sure if it would hold thats all. I figured that everyone must have these things that I have but I saw at the RR day that I was the only one jerking about the car park  ;D

If I can be bothered I will do a bit of drag racing this year so it will have to take some stick. Im just cringing all the time for the poor gearbox now, if that thing grenades then the cars going to the scrappers  :o ;D.

I think I need to have a switch on the steering wheel for a low boost setting to make it more tractable until you reach higher speeds.

i've got a paddle in mine and yes it drives me mad in traffic but it great on track.  don't use the car daily so it doesn't bother me.

Tommo yours is a rigid paddle thats why its harsh. I had it made when i was running my eaton setup at around 175lbs/ft.

it was me that donated you it lol.

you can buy just the friction plate from helix and then make your own pressure plate up with stronger and more springs.
be alot cheaper that way.
