Methanol/water injection

[whitels1ss]

According to the EDS my IAT's today fluctuated between 70 and 80, that was on a 27 degree day with just normal driving in heavy traffic. Might have to look at one of these thermal blankets if the extra methanol jets dont help. How much labour is involved in fitting them?

Methanol jets won't make any difference in traffic during normal driving Rod
because it only injects the water meth after you get over a set level of boost.

The thermal blanket & spacers look like very good value though.

They sure do Ed, dependent on the labour cost to fit.

When you think about it, the IAT's are measured inside a heat soaked metal intake manifold / supercharger
which is sitting on top of a very hot engine.

It only stands to reason the temps might get high,
it's not the same as measuring the temperature of intake air going through a plastic OTR from in front of the engine.

That would be an easy job for you to do at home Rod.

Agree 100% if you do both at the same time (unlike me ). I've now done both (assuming the spacers didn't make way for the blanket), plus upgraded my pump to a Varimax running at fixed speed (didn't make any noticeable difference) but the biggest difference was the 12L reservoir. IATs now take much longer to rise but TBH don't seem to take any much longer to come down again.

Did you need to fit a longer front drive belt when you put the spacers in Gary?

I am going to have a chat with Brad about one of these thermal blankets. From memory, last time I spoke with him he wasn't a fan, cannot remember the reason though. Seeing Wonky's 18-20 above ambient compared to mine, it seems a no brainer to to fit one.

Good point Ed which makes me think they're probably still there as from memory when that was done both the front (longer) and rear belts were replaced at the same time as were fairly worn after 8 years, but not many kms.

Do you reckon I should be able to tell if thermal spacers are still on?

Rod those IAT's are getting up to the higher side aye! Is one of my reservations of going that route as I know heatsoak comes into play also with all LS's

Yeah Mick, I am not happy with them. Also, what are peoples idle speed for their VE autos? Is mine a tad high?

Does seem high for an auto, Brad may have set this up a bit for the LSA blower perhaps mate?

[Wonky]

Will try to remember to double check next time I use my car (probably Fri) but am 99% sure my typical idle speed once warm is around 625rpm (600 - 650).

If they are on there you can see the spacers easily between the heads and the supercharger manifold, they stand out like dogs b@lls.

Mine is sitting a bit higher than I would like, my tuner is going to adjust it down the next time I see him.

What heat exchanger, pump and reservoir are you using? They're different superchargers so there will be some differences but 80+ degrees seems like it's not cooling the charge air anywhere near as efficiently as it should be.

If its the standard LSA stuff, check the pump is still running. If there's air in the system it will shut itself off after 10 seconds or so. And they're a PITA to bleed.
