Don't forget the ~300bhp Cosworth Turbo Xtreme built by Clem Robertson.
Having experienced this from the passenger seat when the engine was
being run in and watched it on track, the car was not only powerful, but
coped with the power too. The car also spat flames out of it's exhaust
for fun, which was great to watch at night.
I'm aware others have build Cosworth Turbo Xtremes, but don't know their
claimed power outputs.
Not a road car, but John Sampson had a 500bhp (or was it 600?) Rover V8
in the car he built for sprinting.

I mostly drive on the low boost as on anything other than a very dry
road it just spins the wheels. It certainly has surprised a few people
that I've taken for a run. They never believe me when I tell them how
quick it is until they experience it.
It's being well used Matthew. Another 300 miles at the weekend with
the Clan McWesty guys. How do I know about the top speed - well
firstly, you told me and secondly, i saw it for myself.

At these powers, the power I think would make no real difference, it
will come down to driver skill in getting the power down and the gear
changes.
I struggle getting quick gear changes in my diesel BMW these days and
that has a much better box than the old fords. Next car will be an 8
speed auto if I can help it!

My 2+2 was putting out 260bp about 10 years ago when it was last on
a rolling road.
That’s from a 2.0 ZVH with a standard 2.0 Zetec bottom end, custom
CVH head from the same person that did Mathews, a Piper 285T cam and
a standard T3 turbo.
Most of that power is coming from the big valve head.
We never did get both mine and Matthews together on a drag strip to
see which one was quicker.

Hi Andy,
I too had a CVH with twin DCNFS and Kent cam. It produced around 120
and I had it for 8 years. It was great fun although lacked out and
out power for overtaking.
I was fortunate to buy a Zetec turbo powered 2+2 in May this year.
Those who have been on here for a good few years will know the car
as it was rebuilt by Jim Hearn and Matthew Wastell with a very
special engine developing approx 250BHP. It is very very fast.
Probably the fastest car I have driven that wasn't a race car. 60
comes in at sub 4 secs and it will go off the speedo (140mph is the
speedo max) before hitting the rev limiter. Even allowing for speedo
inaccuracy, that's still mighty quick. It's an extremely well built
car and a credit to both Jim and Matthew.
I would have loved to have converted my original car to this spec
but I don't have the facilities or technical know how to do that,
especially the electronics.

I've been thinking about my 2+2, it's probably the quickest Quantum
I've owned. The last one I had was running a 1.6 CVH with twin 40
DCNFs and a Kent CVH22, which was OK, but still a bit slow.
The current one is a 1.6 CVH turbo EFi, with a 165 chip and
standard injectors. I think it'd probably see about 150'ish. At the
moment, and touchwood, it seems to be a reliable state of tune.
I dont think it's a patch on what some people have done to theirs -
do we have a fair few 2.1 Zetec turbos, ZVH's or Duratecs hanging
around here or are we in original donors engines?
Idle curiosity on my part, always interested to hear what people
are up to and check out the specs
Andy
