How high can I rev the car without being mapped?

[after_shock]

Just curious as had the cam put in and need to drive it to Rapid, whats the max revs to keep it under as its not mapped for the cam yet?

Cheers

drive it sensibly, no over revving, you can pull 70mph at 1500rpm, theres a good guide

[Magic919]

Rev until it sounds really bad then back off a bit.

I would think that keeping the load down would be more important than revs. If the mixture is out then the higher the load the greater the risk of running lean and overheating something. Also stay away from any areas where it doesn't feel happy, indicating that the mixture is probably out there.

Just be sensible until it's properly mapped. I doubt the cam is that wild anyway probably no or little overlap

What cam duration/lift did you end up with Mate? Any other mods included at this stage?

Just a hint, make sure it's logged for knock when it's on the dyno especially at at WOT, otherwise hope it all goes well for you.

I will have to dig the cam specs out, I cant find the E-mail with them on at the min but will have it somewhere!

Thanks I hope it all works well at the same time aswell

Other mods were manifolds, cats and air filter changed see what it all adds upto!

why on earth didnt you have it mapped at the same time they were installed?

Because the place doing the install doesnt do mapping!

basically keep it out of open loop, (ie) Stay at light load.

And it's not often you'll see Rich write that. He'll be saying the MAF will help next.

Sadly you are correct. In untuned form the maf will help. If you have changed injectors you should not drive it at all!

You will likely wash out the bore etc. You need to set injector flow before you do anything else.

Not changed the injectors they are getting done when it gets mapped.
