so.
Its a totally different monster. I've had m3, 540i, 435i, AMG merc, vr6 and many other fast cars and non are anything like the westfield even
with 269hp. I have mates with 200 who can chase me down on the road as the turbo power is not linear enough.
Aim for a nice linear power line and 220 and you will be blown away.

400BHP produced by a Rotrex is perfectly usable.

Jeffw.
I can't comment on that sorry I've not driven one. What I know is from caterham and westfield drivers who either race or do fast trackdays
say the sweet spot is around 220 to 240. Don't get me wrong in the dry my westfield was great fun and after Bailey improved the progressive
power it was OK.
Then there is the damage to the body. I had to strengthen mine to take 269 on boost. Chassis twisted. Then the crown wheel on the diff rounded so new
lsd. Then the prop shaft broke which was from D and f in Leeds so new landy one made. Then a half shaft broke so put standard ones back on then other
went. So 2 new at 800 quid a pair for rs ones made up. Then the clutch started to go. Then the rear diff mounts twisted. Then the rear arms of the
axle ripped off. So after fixing all that it was fine.
I guess this is the same as a lot of discussions here it's about driver skill which I've only done 60 or 70 in my life so can't say
I have good experience and 400hp would likely kill me haha.
I had a busa mk car on loan for a day think that was 220hp
and 500kg ish that was great fun best car I've driven.
That said I want an ecoboost with 350hp haha

around 250. I anticipate the car will see a fair amount of track action and rebuilding after a thrown rod would be expensive. Worth it for peace of
mind to me. Pistons should be good for 300 so a good margin of safety there and can stay as long as I don't find any horrors in the bores when I
get in there.
Dave, did you get around to fitting a turbo, if so how did it go?

No, complete change of direction.
I now have a GBS Zero sat in my garage being built (Gen 2 chassis).
Decided fabricating all the parts was just too much like my day job.
Zero has all the upgrades including front end wishbones, calipers and discs. Rear fully adjustable rose joint. Unique atm as the rear upgrade
hasn't been released yet.
Engine will be with me in a couple of weeks, Duratec I4 2.5ltr mated to mx5 mk3 gearbox (both new).
Diff has a J3 Driveline plate type LSD.
Everything on the car other than the diff casing is new so will be a new reg.
Initially will be using TBs normally aspirated but have plans to add a rotrex supercharger if I need more ponies.
Should be on the road middle of next summer.
I haven't written about in on here as definitely not a lowcost option.
