In the right air that should be good for a bottom 10, high 9 second pass. Will run more consistent then a cam, header,93 octane car.

E50-60 makes the same gains in power as a cam/93. Ethanol is much more tolerant of heat and higher manifold temps.

Look up Jorgelovesspeed YouTube channel. Bottom 10's @ 135 with headers, cai, e40, drag pack, tune.

That is similar to
Henessey's HPE 850 93 octane package.

I'm shooting for a similar power goal as the OP. I'm not sure which fuel route to go? Injectors? Low-side Pump? Hight-side Pump? Or a combination?

I'm also planning on running flex fuel. I have had a few people say go with the Low-side Pump, I'm really confused here. I should also note that I was planning on running Lingenfelter's lower pulley kit to run more boost... but idk maybe this can be omitted if I can't get optimal fueling.

You're in Michigan, so call KaTech and they will answer your questions. I know of no better shop.

Looks like if I want to stay on a blend 93/ corn I will need to do cam/ 10% lower and be right around 700 tire. If I decide to go 93 I am thinking blower port, 15% lower, and 103 TB and be around 700 tire. I assume the first setup would be more consistent and run cooler. Thoughts?

Chad, in 140+ posts, you've gotten input here from some of the most knowledgeable Camaro guys anywhere. Surely your questions have been answered above?!

Yes sir!! I have a few options from all the great input. Thanks to everyone in here! I will start ordering the parts soon and I will also post dyno results and my drag times this spring!!

Yes, KaTech is right down the road, but they won't tune for FlexFuel which is a bummer... it's basically free power. They recommended a Ported Blower and some other odds and ends. After some internal deliberation, I may end up doing that (instead of a pulley kit).

Nonetheless I still want to run FlexFuel (E60) or full E85 if the stock fuel system can handle it... I'm pretty certain it can't though... and I'm getting mixed signals on what mods I need to achieve that with or without a pulley kit.

You can always run meth instead of a cam. Some people are into that... me personally I stay away from meth and any kind of standalone unit... if the units malfunction you're looking at a bad time, but I've never personally ran into people who's kits have had issues.

[ChadSZL1]

I agree ☝�� I think meth is somewhat dangerous. I want to stay on some blend E40-E60 for the smell, cooler temps, and extra HP.

Pulleys reduce your ability to run flex fuel. But flex fuel makes a lot more power. Run the flex fuel and keep the stock pulley. That will also keep your heat soak in check.

If you want to run much E content then get FIC +30, LPE DI pump, and low side. Should be able to run up to E80 or so with bolt-ons stock boost and likely even a 5% lower. If you keep E around 60% probably can run stock low side. It's hard to pin point exact amount of E you can run. Most pumps are usually E65-75, but some are E90. Elevation and temps playa a factor too. Either way the fuel system upgrade will allow a lot more E then stock system.

Then if you decide to go further your fuel system is already there. Just get a cam with a 43% fuel lobe and low side if not already(cordes aux is a solid setup). Then you will be able to make big power on E.

With E85, you will need roughly 25% more fuel by volume compared to gasoline. The stock fuel system runs out of fuel around 670whp peak (assuming 530whp baseline). We can get very close to that number on a stock LT4 blower with no cam on pump gas. You still aren't spinning the blower that fast, so heat is not as big of an issue as it could be. Ethanol based fuels do have a ton of benefits, but unfortunately it is difficult to run reliably in blends. If you are maxing out your fuel system with a blend, and you accidentally run more ethanol, you will end up hurting your engine.

With a DSX low side, a flex fuel sensor, and no other modifications, you may be able to get away with full E85, but you would end up at less peak HP than you could be on pump gas using the same amount of fuel volume.

Methanol can be a good route to go as long as you are up to date on maintaining the system. A professionally installed methanol system is not as unreliable as you think, I would just plan on replacing the pump yearly for peace of mind.

This mirrors exactly what I was told by Vengeance Racing when I was setting up my build.

There is no reason for anybody to accidently run more Ethanol % then there fuel system is capable of handling. A 15.00 obd2 blue tooth scanner and the Torque Pro app easily allows to check Ethanol content from your phone. I check mine every time I put a blend of E in my car. It's also easy to figure out blends...there are apps for that. 4 years and lots of E later my SBE LT1 is still alive pushing 11psi of boost.

Your statement on pump gas makes more power on less volume is accurate but it's not important. Upgrade the fuel system and reap the benefits of being able to maintain optimal timing even at elevated manifold temps with Ethanol. That is the problem on 93, these engines are knock prone. The stock blower on stock boost still generates enough heat that you are consistently up against the threshold of KR and timing pull from heat and not enough octane. Ethanol fuel even blended down to E40 will allow full timing even with 30+ degrees higher Manifold temps compared to Pump gas.

Stock blower stock boost car is going to see MAT go into the 140's on a 70 degree day with the engine up to temp. ECU is set to pull timing with anything above 132 degrees. Switch over to Ethanol you can bump that table up to not pull timing until 155-160 degrees and the engine is still happy. No KR and the MAT likely will not hit those temps...so no timing pull ever even on a hot day.

I get that some of you big shops have to think about the average customer and his/her abilities. So you spec packages out to keep it simple...but let's not pretend that E isn't superior then every way other then it can require a little more effort on the end user.
