Methanol kit on N/A?

mr.ralliart · May 15, 2009, 02:08 PM

Hi guys. Today I was chating with a friend who has a 99 civic SI and he told me about a DIY methanol kit. He claims he dropped his 1/4 time in .4 sec with the home made kit. He has header, downpipe, straight line, CAI, repro.

So I was wondering about our cars with the meth kit, has someone tried this in his RA?

Do you think we can lower our times in almost half a second?

Nobody guys?

Yes, if he is tuned for it.

In fact the first cars Snow's performance water/methanol kit were develped on were N/A. Particularly a white fox body mustang.

With it they were able to advance ignition timing without using expensive high octane fuels.

It would be similar to if your friend got a tune for 100oct. He is going to make more power and can drop his time.

IMO, it's unlikely, without tons of supporting mods and some pretty aggressive tuning. I really think he's exaggerating on the time.

In my experience you can have a cheap meth injection kit and you can have a good meth injection kit. Now choose one. If you're not port injecting it you'll suffer the same difficulties as these 5th injector turbo kits. Cylinder balance is increasingly important as you tune the car closer and closer to the ragged edge. This is the #1 thing I do that makes the race engines I build and tune faster and more reliable than the next guy.

Ok, thanks for the info.

I've decided to go turbo, will you suggest buying and installing a meth kit? If yo do, which one is the best for our cars?

I haven't looked at meth kits for a few years so unfortunately I can't recommend a brand. You should find one that is programmable and has 4 injectors on it if you really want one. I'd say boost the car first then think about meth.

Will do.

snow has been a reliable source for alot of drag racers running higher compression or high boosted vehicles. The meth kit will lower cylinder temps which will allow for more timing but won't really notice the difference in a stock RA. Hackish is right. Go turbo then think about meth.

I know this is a pipe dream but over the last week I've spent lots of time working on the ralliart ECU's electronics. The MT ECU has all the stuff for the AT which includes a number of solenoid drivers for the shift solenoids. It is not impossible that the stock ECU could be made to properly support meth injection. It even has the facilities for the proper safety mechanisms too - for example a meth level/pressure sensor that won't allow injection mode if you're out of meth, plus you could use it to properly advance the timing while still retaining proper knock control...

Just a pipe dream. I don't have that amount of time.
