Go faster / run cooler additives

Postby loftladderman » Sat Jul 03, 2004 8:23 am

Yesterday I drained and flushed the water system on the Turbo.
Nothing untoward came out :lol:
I added Silkolene Pro CCA Coolant Additive. Otherwise known as a water wetting agent.
My water temperature run quite a bit cooler.
Visibly so.
Even after a good caning session on my favourite road the temp was down on what it was normally.

I then stuck some Silkolene Pro Boost in the tank and filled up with some unleaded --- NOT my usual Optimax. 96 ron stuff.
This "Additive" is meant to increase the octane, and after filling up I can say I noticed no difference at all. :D
The cheaper fuel was as good as the Optimax and even better in regards to my run on times, when switching the ignition off and waiting on the timer to shut down !

I emailed a pal I raced with on the bikes and mentioned it to him.
His reply I enclose below.
Hiya Mack big lad,
Hows tricks up in that dark, damp, dismal corner of scotland.
Pro Boost is a well kept secret with me.
WHY do you think my lap times were better than yours at Mallory Park last year ?
Not only does it let you use a cheaper fuel, but if you use the higher ROM one, and then add 2% to 3% it is the equivelent of rocket fuel.
It does no harm to the system at all and makes you go like f***.
See http://essexparts.com/newproducts.html#PBoost and you will see what I mean.
It dont show up in any fuel scrutineering either (Laugh).


So do additives work ?
I think these do and so does my friend :lol:

Are you on commission or something?? :lol:

Do you have any additives to keep my air intake temps down as that's the main problem I'm suffering from :( Trying to save up for that chargecooler BRP keep promising to develop for the Mk1 97.

No commision HONEST.
Just that the stuff works for me so passing it on to all :D

As for temps at the air box, I fitted a vented headlight cover and raised the back end (Screen end) of my bonnet the thickness of two S/S washers.
I also removed the trim on the top edge of the bulkhead completely.
This dropped the temp under the bonnet by quite a bit.
I only have a probe thermometer which I taped in place to read maximum temps, but on two runs before and after the difference was down by 10 degrees.
This is of course only the ambient air temp at the air filter area !
I picked this tip up on the USA Miata site :D
They said remove SOME of the bulkhead trim not ALL, like I did.
No commisons from them either :cry: LOL

I've heard about the raising of the bonnet at the screen end trick before. I recently fitted some bonnet lifters and they seem to have lifted it slightly anyway so I don't think I'll add any more washers.

Where did you get the headlamp vent from? I haven't seen any secondhand and the only other place is rpseed in the US, but they were wanting a LOT of money for a rather stylish 3 vent version.

Have considered having mine louvered ........

I bought a pair, and have one left BUT....it is the off side one.....so unless you vent from THAT side it is no use to you !
I only fitted the nearside one as I only required the one.

I got them on eBay of all places....LOL

Bonnet struts do raise the bonnet slightly.
I have them as well, but you need to raise it around 1/4 PLUS, inch to be really effective so its still washers for you ! LOL

Hmmmm... what I could do is buy it off you, fit it, then run some ducting to take the cold air over to the correct (i.e. passenger) side of the car!

How much do you want, and what colour is it??

Morning Si
It comes in white primer.
I had mine white for a week while I tested it and then I sprayed it up with a Halfrauds red paint, NOT a colour match to the car, but close !
It was just not worth setting up the compressor and spraying gear to do such a small area.

It is a total PIG to cut out the vent panel, and I drilled holes in mine instead of cutting it.
I then backed it with wire mesh (Small mesh of course).
If you wanted it as a slot and not holes you would require the patience of a Saint and a pad saw or some other very small cutter like a Dremel.
A jig saw is too large.

The tube / venting is easy and I used 4" which is easy to bend and alter to suit.
See photo below.

Again I left these sort of loose until I found the optimum position for them (I used two).
I removed the outer (Left hand pipe in photo) one which I had run to behind my radiator as it was doing nothing at all bar taking up valuable room !
Because of the large intercooler in front of the radiator my rad does not allow any cold air through at all !
All I was drawing was hot air in that one.

As for cost.... ?25 if I post it or ?15 if you drive up and fetch it.
OR...?15 if you wish me to deliver it on my way back to England Tuesdat morning this week and meet me early on the Bridge Road / A 720 somewhere, on my way to the A 68. It will be around 06.30 / 07.00 hours if you can suggest a Services or place to meet.

OR ............Bring pipe work / tubing up here, and we will do it here next weekend, and call it a technical day ! LOL

The fuel additive is used by the local TVR dealer in his 230 horse NA Metro, it works there

Hi Richard :-)

Postby loftladderman » Sun Jul 04, 2004 2:01 pm

Thanks for that link you sent to Si !
Damned good value for money those ducts and fittings !

Edzell was a WASH OUT and I was only running low 15 secs !
Track was well puddled and spinning wheels and aquaplaning was the order of the day :cry:

My pal turned up in his Caterham and was laying down mid 12 second runs !
Amazing.
Maybe selling all the Roadsters and investing in 2 Caterhams me thinks ! LOL

Was having a closer look at the engine bay today and it's going to be a real tight squeeze to get some ducting over from the drivers side to the passenger side so I'm not sure I'll bother just now. If anyone hears of passenger side louvred headlamp covers going I'd be interested ........

Tiss OK Si.
They do sell them singly as I have seen one for sale on eBay earlier in the year...a near side one, which is what you require.
If I spot one I will send the link to you :-)

The link I posted shows NACA ducts. These can be fitted in the lid.
