you'll see when your car gets running, at bigger boost numbers it uses A LOT of fuel. twinturbogt isn't that far off.

2.4 times more off methanol then gas will hurt your engine, I have tried...
You need to be somewhere around 3 times more, perhaps 3.5 times more.........
When guys like Mike make close to 4000hp that is a lots of meth !

Yup... You'll be looking at an enriched a/f of:

100% Gasoline @ 20,000 BTU's/lb 11:1 to 13:1

100% Ethanol @ 11,500 BTU's/lb 4.3:1 to 8.2:1

100% Methanol @ 8,600 BTU's/lb 3:1 to 5.9:1

100% Nitro "Top Fuel" @ 4,900 BTU's/lb a/f of 1.1:1 to 1.7:1

Good news is that those 650lb/hr injectors he's talking about are about 4X the size of the 160's and most of the big boys (moran aside) are getting along pretty damn well with just 3 sets of 160's so they should be plenty for the rest of us mere mortals and won't require the extra effort and expense of setting the motor and EFI system up for 16 or 24 injectors.

The best thing about these, are that they are compatible with just about every aftermarket injection system available. make sure to check out the write up in next months Hot Rod Magazine. thanks guys!
You guys got a contact number so I can get some more info on these?

i heard about these this week in the UK. at least 4 years of development...
If they work AND last it'll be a injector revolution.

How many people are idling on one set 160's and bring in the other two sets with staging? Switching to an injector 3x bigger and you lose that option.

i'm running with 300# per cylinder at idle with gas. The EFI is running at 1.1%,so trying to run 450# at idle on gas would be difficult. Alcohol race motors are completely different.

Quick and dirty calculation 300x1.1%=3.3 lbs, 3x for Gas to Meth =9.9lbs from 450# injectors is still only 2.2%, so its not near as bad, but still a bit of a resolution issue. A tenth of a percent (the resolution limit on most ECU's) is still almost 5% more/less fuel per step at idle.

Does anyone have some specs on these new 650lb injectors?

i.e. Opening time, min and max duration, max current draw and some pics and pricing if possible.
