i dont understand how the little polo's do not get a great quarter time ? ..

My best mates civic was 181bhp in a stripped out eg (still heavier than a polo) and it was 14.1's all day :/


do the polos have that much traction issues at these power figures?

Correct slicks help, alot! Although as Karl correctly states, the actual start has little impact on terminal speed as a fairly general link to trap speed and power with G40 turbos I'd expect:

185-200bhp ~ 100-105mph (Andy and Robin are both in this section)
200-225bhp ~ 105-110mph (Mine trap speed with K03 was 110mph, 108mph with a strong headwind)
225bhp+ 110mph+

Standard G40 traps around 85-90mph, and a modified circa 150bhp one about 95mph.

Slicks and a diff help alot, I found my car was much harder to launch with a bigger turbo, couldn't get within 0.5s of my best time.

Polos generally aren't built for drag racing! But it's fun making them try  ;D

next time am gonna do it without launch control. with the turbo being the size it is i have to launch at about 4k revs. i'll see what my terminals are next time. early next year it will be.

Keep us posted  ....  You should be trapping between  115 - 120mph

powder coated my rocker cover and made a better catch tank with baffles in to catch oil vapor.



few more bits in the engine bay to sort an try to make it look tidy.

Few photos from bodyshop, should be back on the road in the next couple of week.
