Surrey Rolling Road booked for the 17th December.
It will be interesting to see what she is putting out (especially against my mates supercharged 350z)
Guesses on a postcard please, I am thinking around 300bhp at the wheels so 350 at the fly?

I can't remember the exact combo, but I'm sure my mate used a Toyota Land cruiser pressure plate in his blown Rover V8 build and it coped fine.

Well at least its all fresh in my mind and I cleaned everything up before putting it back together. I might just bite the bullet and go for a new lighter flywheel and McLeod twin plate as I cant be bothered to be pulling the box a third time and they are rated to 800ft/lbs
Am going to call Real Steel, John Eales and TVR Power this morning for their opinion but I hope they have something on the shelf as I want to get it done before the 17th hopefully (and also to bosh it out whilst I am still enthused!)

its probably how quickly the torque is delivered rather than outright number (engine capacity + turbo) good call on going over spec. i expect the tyres will be the clutch after its sorted, way easier to change  |

I use cg Motorsport in Leeds for clutches , they load tested my mr2 cover last week as it's been holding 430lb ft but the plate was wearing so they re lined the original and built me a new plate so I have a spare ready to go £130 delivered

McLeod want $350 just for shipping on one of their twin plate RST clutches taking the total to just over £1000, which seems a little excessive (plus the £400 I have just paid for a 6.5kg steel flywheel!). They are rated to 800bhp but I think I will wait until Real Steel have one in the UK and I can compare it to whatever CG can offer. |

Mine is a 240mm cover with a std full sprung plate . Dyno is pulling from 2-6000rpm at 9psi so they should be able to build you something for £250-300 that will hold 450lb ft  Mines a twin turbo with 6psi at 2000 and 9 at 2250 . The Holset will be a bit later being a big single so the torque curve will be a bit more clutch friendly on yours  |

i would humbly advise you try a car with a twin plate before buying- my hks twin is fairly smooth on take up-but is twice as heavy as a normal impreza uprated fast road clutch and is noisy when the clutch is pressed in-i only use my car as a weekend toy so no real problem but it would make it a no go as a daily. couple of hours and i,ve had enough lol.
might be a consideration if you use the car for touring/long distance runs.
the sharp engagement can give the box and diff a hammering too-they also tend to "transmit" more driveline noise so you,ll swear theres something wrong with the box especially on open top cars...
cant say for the rover lump but many of the four pots that i fitted lightened flywheels to, pick up off the line quicker but tended to suffer with a little judder on pull away,, little things like that drive me nuts .
i think the thinner lighter wheels were made from harder materials so the clutch never really beds into the flywheel.
checked my last lightened flywheel during a gearbox change and there was very little wear but the pressure surface was blue from excessive heat,after this i fitted standard flywheels and never had any judder at all-i,m quite sure now that my frequent gearbox blowups (the impreza 5 speed is made of chocolate brownies lol) were helped along by 6 and 7 kilo flywheels
fantastic car mate

Surrey Rolling Road booked for the 17th December. It will be interesting to see what she is putting out (especially against my mates supercharged 350z) Guesses on a postcard please, I am thinking around 300bhp at the wheels so 350 at the fly? I'm going to guess at 376bhp and 340lbs ft torque Hope you manage to get the clutch issue sorted though, would something from the Bowlers be of any use to your setup? |

Fancy having to postpone the rolling road day due to the Japanese boys getting worried... haha!! Can't wait for this clutch to be done so we can find out and I can have a ride!

Shiny bits arrived today 😁  The 15lb flywheel is quite common fitment in the TVR world with no reported issues but thanks for the words of warning. Seeing as the car is only around 1000kg I think they can handle lighter flywheels quite easily as there is not a lot to lug around! |

Good thinking I will look into that! Clutch will be ordered this week whatever happens so I will keep you all updated with my choices. Judging by figures from other turbo Chimaeras I think the torque will be in the 400's though! |

I am going to guess at 364bhp & 408 lb/ft. If I'm the closest do I win a prize?

Just had a chat with CG clutches, the best solution they recommended was to send them the new flywheel and McLeod clutch, and they will test and check everything over for me and build a 6 paddle friction plate for it. Total cost around £200 as they say that the McLeod covers are good and worth keeping if its in good condition.
Thoughts on this over waiting for a McLeod twin plate?

as has been said before, youll need your spinach in the morning for multi stack clutches, and very severe on off action. i wouldnt consider one unless it was a track day car with deliberately light flywheel and small diameter clutch.
6 paddle clutch will give near standard actuation, yes they are a bit snatchy but once your muscle memory is ontop of it nobody would notice. massively higher potential for friction. only downside is its more aggressive on the flywheel and cover (than standard organic) and paddles wear quicker (than standard) youll be down to the rivets in fairly short order with frequent use, but they are refurbish-able

I've used Mick at cg for many years and he's never steered me wrong yet . I'd ask for the plate to be sprung so it behaves nicely in traffic |
