How many revs is \'over revved\'? I have logged 10060 rpm,and I know I have revved it higher.

around 8800 rpm but the rev limiter was set too 8500 at the time.
It was prbably that which damaged the engine,a cracked tip that\'s all.no other damage.
12 a\'s can easily do 10,000 rpm,just warps the steel tips temporarily though!Until you run it in for a few miles again to flatten them.The carbon\'s and Iannettis can take 12500 rpm or more!
Kind regards

All failed engines Tim?  were these high spec. engines?

Which engine was that Carl? if a limiter was set at 8500rpm - then only a downchange could cause an over-rev couldn\'t it?

8800rpm isn\'t that many revs, even with 2mm steel seals? - sounds more like a tuning issue?

Hi Glenn,
 Clive went up the strip early this year on a very mildly modded engine that I built him and was only mapped to 8000 rpm with the rev limter raised to 8500.mild porting and stock seal\'s with no clearancing.
Because of the gearing Clive was only a few meters from the line wanting to change gear but was instead holding it on the rev limiter just before and over the line.We reckon that the momentum of the car would have taken the revs to around that figure which was none too healthy for the engine.If the fuel was going on and off at those revs we reckon that is what caused the cracked apex seal.No other internal engine damage though.
If Clive changed to 4th gear his time was ever so slightly slower but his terminals were 7 or 8 mph more.
Anyway the engine has now been rebuilt and has over 2500 miles on it, and is waiting to be tuned.The new engine is highly modded,big porting and dowelled with Iannetti seals and should do well over 9,000 rpm.
Kind regards
Carl

Tim is quoting from me earlier.I built them.
The engines in question were not all hi-spec engines.
Gary Goodings being the most highly modded.
Kind regards

Hopefully that was an oversight

500rpm into the unknown!

At the request of the president of the MRC I have re-merged this thread.

Sorry to our members/readers.

There appears to be the normal back patting of some friends, and trying to blame others.

WRONG!!!!!!

Well sadly you wont be covered for lost nutz, however if in the future you upgrade to nuts then an RAC NUTstar tracking device can be installed to ensure you get them back quickly.  
 As for your missing nutz, I expect they\'ve been resprayed and sold into a squirrel prostitiution ring.

Engines blow up when you are developing - as Phil knows and appreciates; Geff and phil have a very good understanding and relationship between them - Phil wouldnt be as keen as ever if that were not the case. Making a reliable package takes development time and expense - and engines, as Tim, Carl et al appreciate I\'m sure; the MoTeC was an unknown that proved VERY(!) problematic  and with little support it was hard to get things sorted out with out trying, killing, rebuilding and trying again (you remember the first engine to go was Carls with Ianettis? so what chance did geffs motors have?). Thats how it is. 12 motors now is it?! I thought it was 7 the last time this came up?! I\'m sure some one is keeping count. Any way, hopefully with MicroTech or Power FC Phil will have a few racing miles under his belt...  

That is a very perturbing post. Support from MOTEC UK aside, if you cannot work out how to drive a high end ECU you should not be a dealer for it. PERIOD. There are also a few bits in the sale of goods and supply act that are potentially pertinent here.

I shall be contacting MOTEC about this, as being a dealer for them gives a certain cachet and an implied level of competency. This post clearly shows, direct from the horses mouth, that this competency is missing.

1. I did not and have never built Phil Gorriahs engine.Tim at RX motors did.I supplied the Iannetti\'s.

I sincerely apologise for the error in my post Carl.

No probs Rich,
Did you enjoy today at the pod.Excellent result that.Can\'t say I\'m not jealous cos I am.Tell Geff well done from me.
Kind regards

Bill - I said that about MoTeC from my view as a 3rd party of proceedings over the last however long. My opinion. Not Geff\'s. He is a MoTeC dealer I am not. Geff owns RE:Worx, I do not; Geff is a very good friend of mine, I spend a lot of my spare time (I work full time for a firm of chartered accountants) messing about at his workshop, learning as much as I can from the experiences it provides me, I help with admin chores and hand him the odd spanner. I\'m sorry that my loyalty toward him obviuosly comes across as suggesting that I am more involved than I am. Please dont confuse my posts/views as being those of Geff...

The fact of the matter is he is too busy to spend much time on here - like the other workshop owners who spend all day working on customers cars and speaking to people on the phone. I see alot of people go thru the workshop tho - and come back time and time again very happy. And I hear a lot of stuff from geff and other people in the business he speaks too daily - both some of which manifests itself in stuff I post on here some times...

Carl - Pod was excellent; I was very concerned about the gearbox after guys first run - but his second run was awesome - it looked fast, he got out of the box GOOD, I was so excited as the gears went in - 2nd, 3rd, 4th - I was willing them to go in sooo hard! I knew it was quick but when it came up 10.61 I was overwhelmed!! ran off to get the slip and find Guy, saw him a way off, punched the air and he did the same - it was a great moment I totally messed up recording the run in my excitement but I know a guy Guy knows was their filming has it on tape though so it should be about some time
