jaffa

no, it's not that simple, you have to check that it can keep up the flow rate at higher pressures. eg 20psi of boost = 63.4 psi fuel rail pressure to keep up I expect it will be fine but just flagging so you know it's good for a turbo application and for other people reading about fuel pumps

make sure the pump is good for the amount of pressure and flow you want to run. As flow demand goes up, the amount of pressure that most pumps can sustain drops

only thing I've seen on Matt's car is that a brake line ruptured on the M6 on the Saturday, didn't see any update after that so don't know if he made it

good results, all the best for tomorrow!

Good to hear mate, is there that much left?

can you show that, as that's what you need to demonstrate to get any further.

Cool, what was the damage? AFR on both banks, if not was it the same bank as the failure or opposite side At least TD are happy to fix the actuators

Mark, don't mean to be devil's advocate, but what tom is saying is correct. Can you describe symptoms before failure and what's damaged? Do you have side mount or front mount intercoolers?

what was the damage? If the actuator was stuck half way I could see 2 things happening 1) slow spooling 2) over boosting, but looks like it was still opening fully when needed, just not closing affterwards so this shouldn't happen. As each turbo feeds the other bank, you shouldn't get into the position of one turbo doing more than the other. That's why stock cars with one blown turbo get no positive boost. Unless you have a FMIC which doesn't feed the opposite bank? This could lead to one side doing more work than the other. Are you measuring AFR on both banks? PS I have some spare pistons, which size are you looking for?

looks ok actually :) I have to ask though, how skinny are those tires!

sorry guys, won't be there, Zed's still broken from knockhill I'm afraid

good to hear it went well :)

good to hear it went well :)

No boost leaks right temp plugs and gaps & spare plugs no leaks no air locks in coolant right fuel for intended use good tires Timing set correctly

it's a stick on sheet, you can see it on the gear surround

happy with mine :)

Well I'm in Scotland! Took 13 hours to get here from Brighton, got stuck on M25 for an hour, took 2hours to clear birmingham and the M6 was painful Anyway, there's a test session this afternoon then timeattack tomorrow, come along if you're in the area

Call Luke, the site doesn't calculate postage very well.

The ZCentre Viper front wings are not wider than stock.

I've found them very good, usually speak to them over the phone though

Yup I'll be there barring any disasters in the week. Won't be full potential but it still worth going so I can get the experience competing

Bob, thanks will make a few calls today and give you a shout later. Mark, This is all wastegate pressure. I have boost solonoid controlled through the ECU, and what you've descibed as boost creep is actually a spike. Boost creep is where the wastegate can't bleed off enough air when open to keep the boost under control.

Dyno session yesterday, was going very well, though again I've had to abort the mapping. This time due to the turbo's. As I'd suspected they were spooling a bit later than they should, which is something I can live with, but once we started to roll onto the power runs at partial throttle we spotted a problem. A run with only half throttle was hitting 16psi, but then boost creeping to 24psi by redline. I'd fixed the boostcreep issue, so I'm 99% sure that the Turbo Company I used have not exactly matched the turbo's I had before, hence the spool and boost creep differences. With Jimmer on holiday, and Jubilee weekend I don't see how I can fix this for Knockhill :( :(

Bugger!

No worries, I hardly see any around too. Traffic was pretty heavy all the way, only had space for a little play on the M25 ;)
