There is one member JBS BlownC5 who utilized tarco and a splash of meth as chemical intercooler on his Z51 M6. Over the years I have found the A4/A6 to be faster than the M6 in drag racing.

If you look at his 1/4 mile numbers and compare them to another member Theofel back in 08 and 09 you would see that he was very competitive with the automatic car which was not a Z51 and had a weight advantage.

If I take similar runs: in the thread
JBSblownC5 11.25 @ 125.07 Approximate Da 07 on 02/08/09
Theofel 11.25 @ 121.01 Approximate Da 212 on 11/22/08

If I correct JBSblownC5's run for the lower density altitude the corrected time is 11.285 @ 124.59. Theofel's corrected time would be 11.253 @ 120.95. Apparently, it worked as the M6 always has a disadvantage, the above mentioned numbers were taken from actual time slips, recorded in the thread.

As I previously stated that I do not use the stuff but it apparently works as a chemical intercooler and does increase performance....if you know how to utilize it as JbsblownC5 did in 08 - 09.

You can not just pour a can in the tank and expect a material improvement in performance. Just as with any modification you have to fine tune its usage. In regard to dyno results I have seen cars dyno crazy numbers and do nothing at the track and visa versa.
Have you ever seen the heads on a car that uses it regularly, I would suggest you do. Your numbers are totally uncontrolled and a ton of variables not accounted for. The variables at a track event are so broad just have a good time and don't draw any conclusions.

Don't you have a video of your 2002 Vette's dyno at Gardenia?

If I remember correctly you did six runs. Three with 91 octane gas, and three with torco, and you lost 18 RWHP.

I was there.

Please explain how my numbers which are produced by the tracks timing equipment are uncontrolled as compared to the numbers you present.


There is one conclusion that is a fact:

JSB way back was ahead of his time using tarco with a splash of meth. Today there are many meth kits on the market utilizing it as a chemical intercooler for both NA and power adder cars. For racing purposes it works.

Thank you for your response, I am done

Yes, they can from what I read. Aftermarket high flow cats are a bit better. I'm not concerned as my tuner said they do fail at times but he has hundreds of C6 and C7's with lots of miles using Meth and Cats with no issues.

The timing equipment is not in question but man look at all the other variables, the list of variables would take two pages.

I dont see how meth, which burns clean, will cause an issue with cats.. First I hear of this.. maybe something new..

I can see having a car tuned rich have issues.. oil contamination from rings not seating, as well as racing with the byproducts.. its not like the car is being driven like a toyota corolla from home to the supermarket. Change the cam, change the tune, injectors, race the engine.. factory cats are not designed for that..

From California Polytechnic:

https://courseware.ee.calpoly.edu/~a...FuelSafety.pdf

methanol is an exceptionally clean-burning fuel – cleaner than gasoline, ethanol or blends such as E85. It does not harm automotive catalytic converters.
And a very interesting article on catalytic converters. Among other things it says:

Catalytic converters are also used to reduce emissions from alternative fuel vehicles powered by
natural gas, methanol, ethanol, and propane.

I understand by itself it won't harm the cat, the question lies if mixing it with fuel can create an issue.. Hard one.. And if so, at what percentage?? 10%, 20/30/40.. etc

If pure methanol isn't going to hurt the cats, diluted (with gasoline) isn't going to hurt the cats.
