I've been recommended to run my new engine with Tetraboost.
Looking at their website I can find all sorts of details about the product, everything except one key piece of information. It's £120 per box, but it doesn't tell me how much is in a box!
Anyone use the stuff?
I just wanted to know how much I'll get.

Tetraboost is suppliesd in 8 x 945ml bottles. Sufficient to make 900lts 4 star from normal unleaded

Ken, I am somewhat surprised if you are talking about the XK. With alloy heads Jaguar engines have been running on unleaded since 1964 in California with no ill effects and my E type has run on 95 octane for 80,000 miles and still only uses one pint every 5,000 miles. If it is for the XK, forget it, you don't need it.
Thanks for the info Dale.
Lowdrag, yes it is for the XK. It's not for the Lead, it's because the new engine has a 10.5:1 compression ratio. I commented to Eike that "I guess that means fussy petrol time" and he said "No, you just use Tetraboost". I'll be talking it through with Melvin to see what they are doing as they set the car up for me. The choice of fuel will no doubt affect how the ignition is configured. We are going with a 123 so it should be fairly easy to adjust, but I'll need to work out which settings to use. The plan is to collect it Friday evening ready to be Dinkel's taxi driver on Sunday :-) Sorry to hear your project is delayed again. I guess these things are just pain stakingly slow, but better right than rushed. It's looking such a work of art.

Hmmm. Now the D type has 10.6:1 and I just run it on 98 with no problems no pinking and just the spitting back of the Webers when cold and when running cool, like in spring and autumn. Apart from that nothing at all. As regards the new C type, we are on target for Silverstone at end of July. Whoopee! And Jaguar the make of the year too! See you there!

Surely it will run well on 99RON Shell V-Power (just as long as you only buy it from a station that turns the product over quickly, because it goes off if its left in the tank -theirs or yours- for too long)? Id avoid Greenergy/Tesco 99RON because of the ethanol content, which although low, may dissolve the non-metalic parts of your fuel system.
If you really need an octane booster then Id recommend Nitrous Formula Race, which is the only booster that Im confident actually achieves anything.

Instant anti detonation in a bottle? I don`t think so.No miracles here.
123 will only supply a standard igniton curve, just a fatter spark. Does it det underload ?
The 123 has a selection of 16 different ignitions curves. Hopefully one will suit the engine.123 will only supply a standard igniton curve, just a fatter spark. Does it det underload ?
I haven't tried the engine yet. It's still at CKL and they will be setting it up for me, I was exploring the practicalities of using Tetraboost, Ultimately I'll take CKL's advise on the octane it needs. He guy who built the engine feels that at 2->3K miles a year, a little lead in the fuel might not do any harm. But as Lowdrag says, Jag engines don't normally need any and Mel at CKL says they've not seen signs of damage caused by it's lack.
I had been thinking of getting some to try, but then the website says minimum order one box - £120+ so it's not the sort of thing you buy for a casual test. Least ways not having just bought a new engine and had a whole load of work done to the car :-)
What I couldn't see was how much 1 box constituted.
If you order the 123, look at the instructions. Total up your advance from your cars tech data and see which 123 curve meets it. That is what the 123 manufacturer says , not me. So what benefit are you gaining over a standard dissy? only one and that is a fatter spark. It is a compromise over a problem I have seen many times. Jag engines need more advance when in the middle of the rev range, not in the risky area 1500/2200 rpm. I have seen the result of un detected det - holes in pistons or the land is eroded away. Believe me it does happen and not always due to ignition timing. Weak mix, poor fuel too higher compression are all factors.
One benefit is the 123 sensors the current discharge per spark form the coil. I has a variable dwell which can effect even out the discharge throughout the iginiton on all cylinders. As a result it suppliers a much fatter spark, nothing else. This gives a better flame burn in the cylinder on compression / ignition,nothing else.

A8hex, I'd be very interested to hear how you get on with a 123. My Mk2 engine is just ready to put in the car after a major rebuild. I intend to run it in on the standard distributor then get either a 123 or a Mallory. I've had a lot of experience with a Mallory on my Healey, it's been very good but still tempted by the 123. What maximum advance are you planning?

One of the guys I've talked to said that the Mallorys could be a bit tricky to get setup right initially, but that was the best they were allowed to use in the race series, where the electronic ones aren't allowed.I'm not sure what the maximum advance will be.
I think it will be a question of suck it and see. I don't know what maximum advance Eike used when he built and tested the engine originally. I also suspect that his setup won't match mine as he was running the engine on Webers and a very free exhaust, whereas I'm using triple SUs and the standard exhaust manifolds and pipework.
CKL will be setting up the engine for me, hopefully ready for me to collect tomorrow - but I'm not holding my breath. I'll have to see how it goes.
I have to say that, while I bow to much better informed people than myself and not being electrically minded, experience shows that the D type, which has Lumenition, runs perfectly and the old E type is still running on points and a standard dizzy and has never caused a moments concern over the years. One thing though that is, in summer, a worry is that jsut the fact of turning on the ignition in the D type can cause the engine to start if it has stopped at exactly the right point in the cycle. No need even to press the button. Now I am very careful to make sure the car is out of gear and my left foot is on the brake - just in case!

If CKL say its` the answer who am I to argue? Good luck your engine and I hope you don`t encounter the problems every Jaguar specialist in the land has experienced and not admitted to.
Are you saying that you have experienced problems with the 123?Most of the reports I've read of owners seem very possessive. If it doesn't work out, then I'll need to change it. I'll be led by their recommendations. They know far more about these things than I do or am ever likely too.
If you have had specific problems I would be interested to hear them, you can PM me if you feel that your comments would be in-appropriate for a public forum.
Cheers
