Didn't one of yours do 208bhp? Or was that on other cams?

The 438's are Ktec's custom ones that are made for them by Cat Cams. This is the specs for both, although they don't list the lift at tdc specs for the 438's 5502421 | 276 / 268° | 240 / 231° | 11.25 / 10.25mm | 0.65 / 2.25mm 5502438 | 276 / 268 | 240 / 231 | 11.25 / 10.25 mm

You'd get the top figures with an epas/manual rack and air con delete too.

The only 2 people i know of that know how to do the timing of the 197 cams is @bloke and @NorthloopCup Probably a few others around that know as well though.

Cat Cams run standard timing or custom (with the non VVT version). Timing the 197 cams in won't cost anymore than what it would to time them to standard.

They need special timing yes. A lad i know with a 172 cup has 197 cams with a standard inlet and it made 195bhp and 177ftlbs at EFI.

438's are the same as 421's apart from the 438's idle better. You can get that power from 197 cams though for a quarter of the price :wink:

That is sexual :hearteyes:

Yeah it is, seen it on loads including mine. You'll need some brake cleaner to clean the cover and each bolt otherwise the silicone won't stick. The bolts don't need to be tight either, 11Nm is about right I think.

That's what I meant, seal under the head of the bolt.

They all leak lol It's a liquid gasket and you can't just take the cover off, it holds the cams in. Quite common for it to leak from the bolts though, take them out 1 by 1 and seal under the head with black loctite sealant.

Never seen so much detail on wiring go into a car this side of a GT/DTM car :openmouth:

I'd cry if it got damaged 😂

You're joking! :anguished:

Can lift the pistons out on the Brembo's by hand using a flat head screwdriver to lever the lip of the piston. Done it a few times on Meganes. Just don't scratch the bore of the piston!

This is too nice to race :anguished:

Better cold start and idle and smoother through the rev range, you'll gain a bit in power and torque but not a massive increase. Worth £150

The drive from Glasgow would be worth it.

So they built a box for you and didn't put a diff in it!!! That's a piss take. How have they managed that.

I mentioned the earth strap earlier in the thread and he said it's intact.

The '98ron map' is an RSTuner thing. But any mapper can map to a specific fuel as required.

I may come down to Oulton when you're there if I've got nothing on. Not far from me really.

Yeah I don't know why they don't mask the holes up. Your other guy you used to use sounds like he did a proper job.

It oversteers a lot more than the previous game. Just have to pin the throttle when it goes.

Might be worth clearing the bolt hole tapers of paint/powdercoat on those wheels Russ, seen loads come loose because of it.

Both Lars and Nick drove the car and were both under 6:50's a number of times. Could have been either one of them.

Lars Kern i think. Could have been Nick Tandy too, they don't actually say.

Probably in orbit now.

Fixed.

Saw this on another forum and thought it was quite funny. Driver didn't seem too happy and slung his helmet into the air 😂 Anyone got any other moments captured on camera? Look how far it goes 😂
