1/4mile in 13.2sec @ 111 terminal on 15psi

i'll check that tomorrow matty but stand revs high then come down and nearly cuts out reset the idle few times and messed with the timing dumpvalve was fucked for one. any thought be greatful

http://www.Zeemax.com

well if the dump valve is leqking in air then fix this first as the engine will lean out

always looking for them bigger bunches of bannanas

Sounds like an air leak.

Check all the blocked pipes on the car, including the lean-out pipe. And check the mating of the manifold.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

cheers lads where this lean-out pipe?

mating of the manifold?

Blocked off the dumpvalve but still probs.

Got something to do with the temp cos when its left standing for a while it sorts its self out, but soon as you drive it then stop does it again.
Really have no idea. Seems to be running cold aswell!

i'll have another look tomorrow cheers

http://www.Zeemax.com

possible air leak like the chaps stated

eliminate these firstley and then move on

i agree but a bit thick and where would i be looking lol

http://www.Zeemax.com

still having probs wondered if anyones got any tip on the best way to go about finding the leak.

Or is a case taking the carb off and doing all the gaskets and putting back on?

wonder if you can use any sort of luquid to see where the leak is?

wheres this lean-out pipe lol does it have another name?

http://www.Zeemax.com

Hi,
Right then, search and you would find....

Lean off pipe goes between 3 & 5 as shown in the picture..... Save the link in your favourites
Try "Bradex Easy Start" to find the leak. This is a spray can full of highly flammable / explosive chemical, so be careful where you spray it!!!
When you spray it on the air leak the engine will rev up...

i'm sure its not that pipe can already crinped when i got the carb so un mucks gone up it while i've been running don't see it thou

where can you buy this spray bat cheers

http://www.Zeemax.com

the stuters and wont get upto speed as well does that been anything? Everything seems right but it runs cold and still revs up and shuts down on idle

http://www.Zeemax.com

easy start is available from pretty much any motor factors and halfords - any car shop really, as bat says be careful with the easy start.

Or use an unlit propane blow torch, a bit less dangerous, but still be careful.

still struggling here could it be intercooler leaking?

http://www.Zeemax.com

intercooler would make no difference, just mean you would have less boost and unfiltered air going into the engine.

i dont no enough about the way engines work but there must be only a few places where air can bring the temp right down. I'm talkin massive diff here from near on a 100 right below 40

http://www.Zeemax.com

could this be corsed by being a gap on the inlet

http://www.Zeemax.com

Hi,
Yep.
I think the temperature thing is unrelated.
Get it running right first, then sort the temp.
Cheers,
Gavin :)

i think your wrong cos it runs ok when its hot just soon as u drive it cools down so much and it starts reving up and down its pissing me off badly cheers the advice thou

http://www.Zeemax.com

Hi,
In that case it's got to be the thermostat...
That's the only thing that would allow the engine to over cool.
Cheers,
Gavin :)

even so it still shouldnt do this at 40degrees. have you also blocked off the dump valve trigger pipe? check inlet manifold gaskets as said, also check the leanoff pipe very carefully for splits, then get back to us if it's still doing it after these things.
