E85carbs Customer Projects and Comments!


Hi Rob, I’m just contacting you to say thank you.  I was in engine dyno last week Friday with my gm iron oval port (#781) head 454 blower engine.

I expected to see something like 500 to 550 horsepower numbers but after few dyno pulls we got 835 bhp/5400rpm and 880 ft-lbs/4200rpm. 574ft-lbs already in 2000prm, and 677ft-lbs in 2500rpm, I think we are now talking about some “area under curve”.

I think those are pretty big numbers compared to my expectations, old school gm oval ports with 2.19/1.72 valves, 1-7/8” headers, 13.5psi boost and fixed (welded distr) 27-28 degrees ignition.

It was a long day in dyno, we didn’t have too much time to make fine tuning in ignition. And we just put those your e85 kits into my carbs and start dyno session, we never changed anything in carbs after that! Like said, I’m very happy with these numbers.

 

What do you think, what would be the maximum horsepower and torque numbers for this set up? 2x750 demons with e85 are pretty small for higher rpm?, 13.5psi boost, (max 6000rpm)? And what would be the optimum ignition timing for max torq/bhp output? Just asking for curiosity, I think we are already beyond the reasonable limit for those old, junkyard ready engine parts. And the torq we have now is more than enough for street car.

 

Now I have the basic setup for the engine, and it seems to be working nice thru whole rpm range. I’ll continue the tuning for low speed / highway cruising speeds with my wideband AFR meter when the motor is installed into my ’59 belair.

 

Thanks, harry

Harry,

 

My kits normally have 1 pv (4.5)and 1 pv plug.   You can add power valves to your order from my parts web page if you want.

Jets or access to jets during your dyno session would be the top of the extra parts. Then you could work on accelerator nozzles to find the smallest that will cover your motors needs without backfiring (minimize fuel waste), air bleeds, idle/cruse fuel restrictor jets, pv channel restrictors would be great for tuning for mileage but they would require top tuning skills.

Ignition control, well my opinion is to toss out any type of boost retard with any fuel because it builds exhaust gas temp and on a blower motor I have seen the loss of valves from high EGT. Locking at 34 to 40 degrees on most motors seems to work well. One thing for that can help mileage is a vac advance dist. We have been working on extending E85 mileage and some early tests running +8 (44 total) degrees at cruse gave us a better fuel eco.

Prices are clearly marked in the website. When you’re ready, place an order through my website. Just add what you want to the cart and when you have everything you need complete your order with the Master Card.

Note: we do not take orders outside of our website.

Thanks Rob Mix

Rob seems to run good in the shop, still might do some fine tunning. Dan May 21st, 2013

Thank you, you built a E85 carb for me in Aug. and it worked great.   I dropped .5 seconds in the 1/4 mile and performed great on Drag Week 2011.  1,300 miles of street driving and 5 days of drag racing.

Thanks Shawn Anderson

 

Hello. I´v got some questions. We got an 71 Olds Cutlass S with a Rocket 350, and want to E85 convert it.

what size of carb does it need, the motor has a Holley 650cc now i think...have not find any ID numbers on it yet. hehe

how much does one cost, and do you ship to Sweden, and if so, how much would the total be?
here in Sweden there is no one that does E85 Carbs for old V8s.


got the carb today.. nice one! :)

and it works great.

thanks for all the help!

Raced Saturday night. Ran 68 out of 100 laps due to radiator failure. The car ran perfect with your kit with no adjustments. I would recommend your product to anyone. If anyone has questions, feel free to give them my email or phone #712-830-4141 or 712-269-8246. Thanks again

I just got a 4412 carb kit from you, I was wondering if you have had any feedback on timing.
I am running a Ford 351 open chamber heads and 11 to 1 comp in stockcar class.
Jason

Jason,
What were you running for total with gas? What gas were you using? 92? 110 race??
Rob

Rob
29 degrees with airplane fuel, 105 octane, I think.
Jason

Jason,
I would start there and add up to 3 degrees and see how it works.

How's it going, Rob? Ken Moody again.  Remember the junky carb that I sent you from my vega. Well, you rebuilt it for me, and did a damn good job on it. I put the vega engine in a chassis car, on straight motor w/ only that 850 E85 carb. It ran 5.87 @117 mph in 1/8 mile; and it's a small block. With that $2.45 per gal fuel I am killing those $10.00 per gal guys.  I hope I have sent you some new customers. Great job, Rob !!!

 


 

From Ken Moody 9-02-2009, This is a picture of my vega 2 weeks ago, with the 750 E85 carb I got from you about 2 or 3 years ago from you on ebay. I love it. NOW!! I have an 850, I put QuickFuel green E85 metering blocks on it. I got an 850 pro comp main body, the right air bleeds, 94 jets, 850 Proform base. It runs terrible. I am glad I have my old 750 that I got from you. This is my question. Is the 950 body you offer already set up for E85? Then what else should I do. If I get the 950 body from you how much would you charge me to put it together right.

Rob,

                I just wanted to send you an email saying how happy I am with the carb I bought from you.  Thank you!   I purchased it from you I think in May and have been driving the car and racing all summer.  Wow!  The car is fun to drive again!   On gasoline it ran 12.81 at its best, now its consistently in the 12.50’s all day long with the best pass of 12.44 @ 107 mph, in a 3,950 lb heavy Chevy.  It’s probably paid for itself from the money I’ve won now that it’s consistent again.   I can drive the freeway again without fear of overheating and in fact I don’t really use the fan all that much anymore, plus my eyes don’t burn from the fumes.  No more searching out for race gas to mix, and around here E85 is about $.95/gal cheaper.  With gasoline it had vapor lock issues,  now I’ve discovered the more heat the better.  It doesn’t ping, diesel, or die in the staging lights.  The combustion chambers and valves even stay cleaner than before.  At first I was skeptical, but with an interest in newer technology.  I’m sure glad I made the change.  Got a lot of other people looking and asking me about it too when they see the E85 bumper sticker and smell something that’s not quite the same as the other cars’ exhaust.  You’ve got a great product, but even more your service is WAY above others which is why I decided to buy from you after shopping around.  Good luck, and thanks again!

 Mike Cole
