Well done big daddy!
Thanks Captain
Well done big daddy!
I get that, and drag racing is definitely a different application than mine. My initial inquiry really revolved around the limits of E85. I have read in various places that real octane ratings are in the 94-96 range, but I also get this is just part of the equation as is the cooler intake charge. I really haven't seen someone claim a limit for the E85, and I am still curious as to what that is. With your setup, albeit with boost of 20+ psi in shorter stints, it is nonetheless super stout. To be able to run it on fuel you can get from the pump at a reasonable price is pretty damn sweet. Seeing its use in applications like yours validates the claims for sure.
Again, great work on the plenum and many thanks for sharing the results. Definitely peaks my curiosity for my 2.8. I'm not a numbers guy, but ways to gain efficiency while adding power is always appealing!
What method of rapid prototyping was used to create that?
E85 = 105 OCTANE
E100 = 110 OCTANE
E70 = 100 OCTANE
That should help your octane curiosity...just google E85 Octane rating and theres a few charts with the break down...essentially what I run is 105 all the time with almost zero chance of detonation. It really is a wondeful fuel.
Without going into the detail of the company and prototype process and material selection.
The guy that made this for me at the work place told me they been making prototype engine intake system (intake manifold, tube, air box, etc) for testing proposes for a long time. He actually shown me a tested prototype intake manifold return after field tested.
The prototype intake manifolds (bolt to the engine) they make has survive 100000 test miles using their prototype material without any failure.
In fact, they use the same material to make special NASCAR intake system for testing proposes and never fail.
One of the high profile show car in SEMA now from a major OEM actually has the prototype intake system made at his location using the same material, same process, same machine.
It happened about a week ago when I ask one of my co-worker where did he got he prototype part make and he gave me a contact and from that contact, gave me a final contact for high temperature, high strength under hood prototype application - later on I find out from another co-worker that location is specialize in making prototype engine parts for testing purposes. I am quite lucky this time since he made it for me for NO cost. I guess when he saw the "GT500" letter in top of the intake tube, he just OK with it.
Definitely not saying it doesn't work like 105 octane race fuel, but I did encounter this:
The Renewable Fuels Foundation states in its Changes in Gasoline IV manual, "There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual-octane engine tests."

Hence the reason I asked what the perceived threshold for E85 would be. Effective at 29lbs of boost does seem that it is virtually impossible to detonate.
Nice work Jay. Nice work indeed. You should have a very interesting next year......Lol I just wondering what you going to do now ? LOL you always need to work on something...
That intake is very nice. def should work well for the people with the big HP setups.
What kind of oil separator or beather tank is that? I sure like it alot! looks like it would work very well.
When are you going to the track?
Wow daddy you really ported that thing
do you have any idea where this blower would land power and efficiency wise on a stock long block setup?
i want to buy something but fear buyers remorse or not having enough air movement for future build.
i noticed on evo. perform website they offer a "kit" with an option for much lower boost. i believe it was 16 PSI. i was thinking that would be an acceptable starting point. how do you feel about that formula? i dont really know how to figure out power numbers hence the questions. would this perform poorly in that application?
