Well it seems one disaster after another this year. Looks like NY or our fuel suppliers here have decided for us, no more 93 octane fuel....I was unaware of the change this year until someone mentioned there station had changed....We only race on 93 and all our stuff is built for it.

So who are you guys using for E85 carbs for Mopars? All I see on QF's website are 3-circuit dominators for E85..

I have reading up on water/meth injection.They are claiming they can duplicate up to 116 octane using pump 92 UNleaded.
I am limited to 4 lbs on pump gas,would be very cool if I could cruise around with pump gas and be able to support 10 lbs of boost.My static is a true 9:1.

So another spacer under the car? That ain't going to fit on my Cuda....What kit for a 4500? I want to compare that with the $1300 cost of a new carb.

Mark Sullens he can modify the carb you have for gas. Or build a new one.
(573) 694-4088 He builds 2 circuits for E 85. He changed my 3 cir. to a 2 cir. He does good work and his prices are reasonable for all he changes. I've called him from thw track on a Sunday and he answers the phone!

If you have a 1/2 inch spacers under the carbs now,you can drill into them for injectors.
This might ignite your interest.Rodney at PRO METH is supposed to be the man.I am not in need of a system just yet.I think I can get to my legal limit with what I have now.The addition of aluminum Dart fueler heads made a world of difference over the virgin iron heads I took off.They CCd@173.

This kit claims to able to raise the octane up to 25 pts.

Is this for all of New York or for upstate only? I haven't heard anything about this, but it wouldn't surprise me in the slightest in this God forsaken state.

That article only seems to indicate 91 is changing to 90, and 93 octane is unaffected.

You can buy a conversion kit for your carb at E85carbs.com , Rob Mix services for around 350 or so. Bought one for my 4150 to switch to E85 He can do custom kits as well, I don't think you have to go the $1100 switch.

The above link will get you there.

a couple of years back the EPA did some kind of deal with the refiners and auto manufacturers to reduce the number of formulations. I think this is going to end up being a "one size fits all" for the whole country. my guess is everybody is going to get California gas; sooner rather than later.

E85 here for multiple seasons. I'll never run anything else if I can help it. DIY kits are one size fits all and unadvisable. Its not a matter of just swapping parts...as most of us can do that...it's a matter of tuning which these kits can't possibly do considering they don't ask any questions about application.

But are you buying Rocket brand E85 or pump fuel?

All carbs need tuning, gas E85, and even new $1100 carbs. I'm sure you had to tune yours as well. Not sure All do it yourself kits are one size fits all. The Kit and link I showed , they are adjustable and can be customized. The Only thing in the kits that aren't changed is the Body itself. The metering blocks have been modified to flow more fuel.

Pump gas mostly from local Sheetz or Marathon.




A knowledgeable carb builder will send you a carb that you bolt on it and runs out of the box, tuned for YOUR engine. Mark Sullens carbs arent $1100, I believe more like $850.

I didn't say the kit wasn't adjustable, but why would you want to start with a cookie cutter kit when you could do it right the first time and have a resource to call if you had an issue? I'd hope the metering blow is modified to "flow more fuel", but it's a bit more complicated than that.

I wouldn't call it a cookie cutter kit, its tuned pretty well to the carbs size. Brule and Frieberger even tested a 4150 e85 conversion same day out of the box over a well tuned gas carb and got like 35/40 HP more over gas on a 500 HP motor or so.

So its no cookie cutter IMO, But, Rob mix e 85 does it All, custom, cookie cutter, new carb send Your carb in to be tuned to Your motor ETC

But If you buy a 4500 from him its like $1280 bucs, the conversion kit is like $350

The 4150s are around $800 or so. I myself bought the Dyno tested cookie cutter kit $315

Just giving the OP some options, I myself at First couldn't even Find any kits for the 4150 Carbs until I stumbled on to Dyno vid and saw where they got there conversion kit.

Oh and your Right, theres A lot more stuff changed then just a higher flowing metering block. High flow needles /power valve, jets, squirters, e85 pump diaphrams gaskets ETC,ETC Check the link out yourself

Before making any changes, check with new car dealer like Audi, Mercedes, McLaren since their high performance cars need 93.
