what is it and what is it for?

 

It's to hold water / meth. I'm trying to sort out my high intake temps on track. 

 

 

are you stage 3 or 4 now then?  

 

 

Stage 2 also has it.

It's only since obdtuner with tmap has become popular, that people are actually seeing what's going on.

How come your temps are so high for a m62 stage 2? I'm only really seen problems with stage 3 and above but even then there not really bad as mine sits around 50 degrees on a boiling hot day giving it some beans. Fitting a water meth kit is only masking a problem that's needs to be sorted.

I was unaware that stage 2 had hear issues...

 

its been tried and tested for yonks

The pikey SC conversion doesn't have the CC rad up front, just a little 'in ear' rad. There are no problems on the road but as you know I drive hard on track and in the summer it got really hot.

There isn't any serious issues with stage 2 with a pro alloy rad up front Beat me to it Neil Can't help thinking a pro alloy rad upfront would be better money spent

oh I see, however I was under the assumption that the big CC system was overkill as after all day on track mine is only warm...

There's a switch in the cabin that allows me to turn it on / off. 

 

So no intelligence in it, whatsoever?

 

Where are you spraying it? Pre-SC, post-SC or the super pikey Ricer special "at the rad, yo!"?

Bigger charger makes for better inlet temps, less work needed to make the power😀

There is an electronic controller, but I'm still reading the manual to understand how it all works 

 

Gonna try a combination of spray points if possible. Won't know exactly until we take a look next week.

No, it's not the physical work that the supercharger is doing that is causing the bulk of the heat. It's the fact that the volume of the inlet manifold is too small and the head doesn't flow enough, meaning the air that is being pumped doesn't really have anywhere to go and is being compressed more and that is generating the heat. The reason the M62 doesn't suffer the problems to the same extent as the TVS1320 is because it's only pushing through 1 litre of air per revolution. The TVS1320 is pushing through 1.3 litres of air per revolution and the TVS1900 would push 1.9 litres of air through all into the same space - that's why it comes fitted to large capacity engines (5.0litre V8's) that can flow enough and consume that kind of volume of air. You'd need a pulley the size of an alloy wheel to slow it down far enough and then it'll just drop out of the bottom of it's efficiency zone and you'll lose one of the benefits of the TVS.

What we are trying to achieve is not more power (it's about as high as you would want to go on standard engine anyway). We hope to lower temps, and not have to dump so much fuel in to keep the combustion chamber temps down (exhaust valves). I was wondering if with the cooler charge and the meth if we could turn the SC slower to achieve the same sort of power, not sure if there is a bigger SC pully available, or if there is if it would be suitable. Currently we are thinking pre charger and post laminova jets, we have valves to allow us to fit them and turn off independantly for testing. Got a lot of testing to do, but our feeling was it was worth a shot as the other route of the front rad does not seem to solve the issue completely, and Neil does really hammer his car on track, 4 or 5 laps at Blyton was enough on a day that was not very warm for the car to severly cut power.

If we fail we fail.

 

P.S. It's an Aquamist control via fuel flow and manifold pressure so a little more control than most systems. That does also mean harder to set up though.

Despite acid being a real track demon his issue is Deffo the capacity of that small rad if you measure the temp of the water coming out from laminovas The rad also only has a small surface area Of cool air from the ear Plus it restricts the cool air flow to engine etc which is also compounding heat issues

I understand that Chris but I still see heatsoak and relatively high temps on the logs from cars with the front rad and tripple pass mod, even on cars not driven as hard as Neils.

Anyway if it doesn't work everyone will know not to bother. It's Neils money, he has looked at the pro's and con's and I am willing to help with the experiment, we will see.

[CHILL Gone DUTCH]

It will prove how good the water injection actually is that's for sure But can't help feeling money would be better spent cooling laminovas to maximum capacity with cool water coming off laminovas so they can't be cooled any better

[Bargi]

There's less complaining about Stg2 IAT because all of them were CS maps/setups with no TMAP or ability to measure. Only since OBDTuner have measurements been able to be taken and pretty much all cars running it are not Stg2.

We hope to pick your brains with your experience of the Dutch ECU too by the way Chris

Help where I can Have you thought about triggering a relay for the water injection to start working From Tmap

We have, the controller has inputs for such things.

Use that rather than a switch
