Methanol/water injection

It was most likely all working correctly when it was on the dyno, I think a fault must have developed after.

The IAT's were pushing 80 whilst on the dyno. Anyway, spoke with Brad and dropping it off tomorrow after work so he can have a look when he gets time. Hopefully something simple.

Hope he sorts it quickly for you mate!

Yikes! Luis said mine reached 54C on the dyno max. Depends on strength of fan etc..

That sounds more like I would expect Gary. Will have to go back and see what temp was that day, i think was around 30 and workshop has AC.

Rod, from memory, I think it was printed on your dyno sheet.

See post number 71 from 19/12/2019


It was 29 degrees, (bottom line of the print, just above the top graph)

I have copied it for you here.....

I think there's still air in the system. The stock LSA system is an absolute PITA to bleed properly. The workshop manual says to do it under vacuum!
If you're doing it at home, you pretty much need 2 people. Flick the car on and off as the pump tries to prime then turns off so to keep it running you need to flick it on for 5-10 seconds then off again and keep going until it's bled.

Easiest way on your own I guess is to put a big container of coolant above the pump so it forces it's way down and thru the system but it's a pain to get it out of the loop without losing coolant. There isn't a big margin for losing coolant before the pump shuts off due to air.
1L in the reservoir doesn't have enough weight behind it, which is why the 12L reservoir works well. 12kg of coolant vs 1kg.

If you're running meth as well, it sounds like both systems have issues.

Anyway, if it's gone back to Brad, hopefully he sorts it out easily.

Is there a high point in the hose from the bottom of the reservoir feeding to the pump that traps air (like an air lock) or something?

It goes straight down Ed.

Not that it matters for Rod as his isn't an LSA but FWIW I did read somewhere that someone had found a quick way to purge and prime an LSA system. Just can't remember where.......

Actually Rod has an LSA blower fitted AFAIK Gary.

I found an easy way as well, get Brad to do it lol. Dropped it off at 1500, picked it up at 1700 all fixed. Was dodgy earth and the electrical plug wasnt 100 percent either. It is pumping like a champ now. IAT never got more than 10 above ambient on way home.

Fantastic news Rod

Did you ask him why the IAT's were so high last time on the dyno?

Oops! Hopefully he hasn't got the same array as the VF re pump location etc..

Pump is located behind fog light on passenger side.
