Thread: Need to add more timing.... (step in Alky guys)

yea that set up looks like it would be alot more effiecent.

i hope it actually works out well. im not saying that i will do it because ive already got my **** plumbed and done, but if i were to ever have my LIM off again it might be a good idea to quickly tap some nozzles in there if it actually works that much better.

nice looking setup. I need to go thur my stash of pictures i got some where someone put a devilsown kit on with the nozzle on each runner and got it to fit around the rails.

I want to see that too. Sounds like it would be a tight, tight squeeze, and whoever did that must have put in a hell of a lot of work.

I've heard about people running various setups that are post-blower, but haven't been able to find much information.

I think everyone is hush-hush to keep their trade secrets safe.

Probably in this case, starting with a tiny nozzle would be the best bet. DO3 is probably the way to start.

If you're talking about the direct port setup that is tapped in the intake runners -
I think that six 3gph nozzles would be way too much. Only the super bored out and blown big blocks are running over 15gph total.

Also, there are a number of potential issues when you move to running a lot of very small nozzles.
Everything from possible clogging, to inconsistencies between nozzles, to just being able to control the flow rates on nozzles that small in general.
The available nozzles usually come in 1gph increments, but when you have six nozzles, you are working in 6gph increments. Not very convenient.

The upside, if you did want to do the direct port would be that you could possibly cut the fuel in your tune, and run straight alcohol at a ceratain point.
I'm not sure how reliable that would be, and you would definitely need a really well built system with good failsafes, but I think it would be really cool to have an alternate high octane fuel source in the car to use on demand.

There's a company called Nelson racing engines that built a supercar (iirc it has a much higher hp/weight ratio than the bugatti veyron) that has two gas tanks.
One was the main gas tank and held pump gas. The car would run on that when cruising, and then when you start pushing the engine it switches to race gas.
I'm not sure what method they did that, but I think that idea is pretty damn cool especially for a street car.

you can run windshield washer fluid, but its not that concentrated with alcohol, so something stronger is usually better.

since im turbo'ed now im still running methyl. im using a 70/30 methyl/water mixture along with my A2A intercooler. without spray i am prolly in the 11.5-11.6 and since methyl drops/richens the AFR typically by -1 which i do see on my WB at ~10.3-10.6.

when i was s/c i was able to run like 23-24* of timing on a 3.4" pulley setup and it helped on the topend with a M7 nozzle.

Right now I use windshield washer fluid with a bottle of heat.

It has to be the coldest rating you can find that has the most alky in it.

just buy a drum of methanol. its not cheap, but it will last damn near forever. if i really wanted my car to go fast id run methanol in the gas tank.
