as above, does any 1 know what they rev up to when standard?
just want to know if my gauge is reading rite, i think it revs out at 6300 RPM
Should be more than that. From the top of my head it should limit at 6700rpm

^^ agreed its same as x16xe as i checked this up few couple of weeks ago, max hp at around 6000rpm ???
X16's are 6300, My superchipped X16 ecu went to 6700 tho.

Not sure what's been done to mine as the limiter comes in at 7300 lol
Won't hurt to post this again as the info above isn't quite right

These will be hard limits, I suspect the soft limit will be ~200 rpm earlier

i was close enough lol
6k? 500 rpm is masses lol, well it is when you run 7800rpm ;)

well i did say agreed to 6700rpm for rev limit but max hp at around 6000rpm for standard.

so c16xe should be 6500rpm yeah?
and thanks for info :thumb:
I am sure my old x16 were 6300, it always seemed like more power could be reached if it revved higher to!
my old x14xe limiter was set at 7k and that was a great little engine! loved to rev!

The info is from Vauxhall's TIS software - so the horses mouth so to speak. It does however say that it can be adjusted with Tech 2, so it could have been played with. Bear in mind the dials aren't massively accurate so you'll never really know unless you hook up something like Tech2 and see the ECU recorded RPM.

No worries. Yeah the C16 is 6500.

will a powerbox raise the limit?
No the limit is to do with the ecu. you need to have the chip re-programmed. But to get the best out of the powerbox you need to raise the limit as it changes the powerband to the top end of the rev range and I'd advise some ARP rod bolts.

You advise ARP's because of the powerbox or if re-programmed?
And would i be better off puting x16xe loom and management in or keep c16xe?
Thanks again for all info :)
The rod bolts (ARPs) are to allow you run the higher rev limit with a greater margin of safety. For example on standard rod bolts, running at 7k for very very short periods of time would just about be ok. With ARP's that moves to 7800 (or 8k depending on how dangerously you like to live lol).
Phaser, I will be having my DTA S40 set up in the coming month, thanks for the base map by the way. What would you say would be safe to rev standard rods and pistons too with ARP's just then I can let the mapping guy know how far to go!!!
No worries mate, hopefully it gets you going at least!
Well I had a chat with Allan at Velos when mine was done and IIRC he said 7500 was sensible, but he did say occassional use at 8k would be ok, again depending on the size of your kahunas lol
I have my hard limit at 7800 with the soft cut at 7500 or 7600 (can't remember off the top of my head) - the DTA will never catch it at the soft cut, it'll always go a bit over this. So I'm somewhere between sensible and daft :)
And you never had any problems with it? Are you using a solid tensioner on the cam belt?
Don't jinx it, it's coming out the garage this week lol
Been fine with all the abuse I've thrown at it over the years. Solid tensioner is an absolute must on these, so yes do run one. Not cheap but cheaper than the top end.
Thats the mistake I have made on mine it doesn't have one!!!!!
I found out after I put the engine back in the car Martin Bowyer does one for about £10!!! I looks like there maybe quite a bit of room to change with the engine in situ though.
£10? That's cheap!
You should be able to sort it in place, the nylon one would be done during a belt swap anyway.
Yes extremely! A friend of mine has just got one from him for his rally car after his failed and smashed the top end to pieces! Hell of a lot cheaper than the likes of SBD.

i think i will be getting the rod bolts (ARPs) before i re-map then, where would i get these from? send me a link if possible? and i like to take my car to its limits lol
Thanks
RSM Motorsport in Morecambe, the woman there is really good and good prices too.
Make sure you get the correct bolts though I originaly bought rod bolts from a company called part box which said they were for a 1.4 16v Vauxhall engine but they wouldn't fit, also the company wouldn't return or refund me which i thought was out of order as they were advertised for a small block 16v engine but weren't fit for purpose.
I think I paid £69 for my ARP's delivered from RSM, and to help you get the correct ones heres the part code. BEB-24/8 (that is Kent Cams part code as they are a official importer for ARP its where Bill Falconer,rsm etc get there's from) You can't buy direct from Kent Cams.
I hope this helps you. :thumb:
