Best value performance mod after de-cat exhuast for valver?

[Andy P]

Backup.....love it

[nyk]

lol...

std engine, with de-cat and zorst. williams shud run in the high 14s.all day


mine ran 14.6s at best with these mods.

Well apparently you can get 14.1, so either John is a shite driver (which I know he's not) or something isnt right!

zzzzzzzzzzz

[richy]

id just like to say......


who gives a f**k about 1/4mile ! you want a quick straight liner, buy a drag car

You're just saying that because you have a 1.2

you not read my location thing? i also have a williams and a valver lol

???????? john who??



14.1........yeah its doable with less weight in the car....plastic windows, 1/2 missing doors etc.


think the 14.6 is still about the quickest for spec n trim tbh. not really sure now....but like martins.....take enough metal/glass out the car and the times will fall.......obviously.


for the price of cams, pullies, map, fitting etc. ud be better off gettin an f7r, cos it would work out cheaper, and ud have a more usable power plant, with both putting out roughly the same power.

Andy's did 14.1 with rear seats out and bucket seats....with same engine mods as my old one, supersprint, exhaust & hillpower chip.

My williams did 13.91 with full cage and 2 seats in....

The best 16v is 15.2......says it all really.

[Martin]

Andy's also has 185 bhp....I'm a believer, there are some freaky good f7r's out there!

[Andy P]

Richy i know you dont have just a bug eye.

All this talk makes me want to keep it

[Jamie.]

after decat and stripping i believe it starts to get quite expensive... i personally would never strip my williams as its sacred but the next mod(s) im hopefully going for is a reworked head and some cams... btw, what are the options to get cams timed in? i can have a remap from chip wizards but how else can i go about it?

LOL @ this thread.

Speak to anyone in the know about these engines, and its obvious the result. For the money an F7R is defo the route to take.

Seak to "Craig" on here. His old F7P cammed, headwork (i think), remap was not much quicker than a std F7R. He had spent a bomb on it.

The F7R offers so much more low down torque, which means a lot more than the 13bhp gain over the F7P.

Std F7P is on average 1 second slower over the 1/4mile than F7R.

Look at the "nana" for example. Cams, headwork and remap on 90ishK bottom end is knocking on 200bhp. Would you ever see that kinda power from a supposedly superior F7P???? Costs the same for the cams, headwork and remap on either engine.

Plently std F7R's with breathing mods have ran low 14's.

Martin, Andy P, Midge, 2live, myself...etc

And then there's the driveability of the F7R with better low down torque for track use etc, and camming an engine gives more power, but reduces the driveability as the power range is reduced and often at the top end of the rev range. These effects are much worse on the F7P than the F7R.

If the F7R was a poor building block why are there so many hybrids running around. Its clearly the better route...

nuff said.

Just IMHO of course! :P
