No need for a row people.... a sensible discussion on cams is where this is at

9bhp is not the whole storey (I am talking generally here, no reference to anyone of anything specific).. its the way they drive and getting as much power everywhere, at all throttle angles, all rpm ranges. Andy

and we all know you love Shrick Fred, dont worry its etched in our minds.

"in that range" as in the CAT ones the shrick will have the same overlap, and will be more expensive. they are ok though

Personally yes, you will get similar power gains with that as 428's and a remap.. plus it will drive better

bit less cost wise andy, but pricipal is there

Brian Yes.. SC power isnt HUGE! but it is very fast.... but very tractable.. As Andy says cams and itbs are close to SC low boost cost... but they are different in delivery..

about 10 bhp Brian I would always start with the management as then you have an open book as to which direction to go So Yes personally I would wait Andy

Yes

428's are currently the only option in that range to run on stock managment 421's or above wont idle

btw its not turbod... footer on graph hasnt been changed.

std 172 with itbs, vs itbs and 421's

yea, then didnt like it and broke it and sold it

that was his old engine, not the new one........ we power ran it as it was mapped after we fitted bodies about 2 years ago with its previous owner.

that sounds more like 423's which are way too wild for a stock engine

421 cams, ITB's Nice spread of torque.

CAT 421 cams work well. 215bhp ITB's 421's work well, linear power delivery. Andy

I did an F7 knife edge a few years back... got some pics somewhere if you want. Andy

I was talking about the AST's they may not suit your driving style Fred. On track for HARD driving I needed them to be stronger... not softer....

Personally I use AST dampers. We sell both. I find the KW's dont give the chassis control I like in comparison I like the fact that I can re valve them, the build quality is excellent. These are my personal preferences Andy

A world 1st, Dan and Fred agree on something... I have to agree, on a TOP engine it may be worth it, but I certainly havn't bothered on any of my engines for myself. A decent balance as the guys said is far better, removing weight from the flywheel is as advantageous really in this instance. Andy

Sorry, no springs kits available in our clearance.

Correct we are, if you get in touch we can tell you more

Just 3 kits availabe: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110458959037&ssPageName=STRK:MESELX:IT#ht_500wt_1182 David.

For a RR day its not easy to get everyone through I have a tacho pick up that goes onto the coilpack so it will be possible to do easily

How about these? http://www.k-tecracing.com/show_product.asp?id=2365 Good allrounder at a good price! Sean.

Re: Cup TT ?? 20v engine is good, but its heavy so needs MORE power Min 300bhp to make it worth doing. To do it properly though is not easy, as it needs engine mounts, alot of subframe work. if its big power custom shafts are a must as well.

Dean when we are our 172 LPT Demo running "again" in a couple of weeks your welcome to come down to have a look Andy

We tested some throttle bodies last week with the PTFE gasket in place after a normal road drive the inlet run was stone cold, normally this would be quite warm Andy

We used to find on the rollers I have used in the past that wheel calculated speed is reasonably accurate upto certain speeds. but they as the tire inflates and heats up the losses were inaccurate. So on higher revving engines this of course causes errors. Tacho pick up (not the inductive type...
