I’ve noticed that the more power that a vehicle is making the faster it runs through the dyno pull. You could definitely tell how much faster it went through the pull after you bolted on the bigger supercharger. Congrats Eric! I watch a good bit of dyno stuff on CZcams and this is one of the most impressive sessions I’ve come across.
I have a sniper I ran into the same problem out of fuel I got some 210 lb injectors and switch to 100 lb injectors out it'll cover whatever you trying to do.. 👍 love the channel good stuff you break it down and let us know how it works we in the same boat with you so it helps us a lot for sure I really appreciate what you put out there..
Nice to see 32 years later after I built supercharged Trucks for Accell, Vortech, Paxton, and Chevrolet for SEMA that the HP dyno #s have not changed. The only thing that improved is the Data collected. Your running just about the same HP we made in 1995 with Vortech and a Lingenfelter tuneport for Mr Gasket Booth at SEMA in 1995. Great Channel
@cedricwilson2055 when I was building the engine GM racing gave me a ZZ4 to be introduced in 1996. Vortech, Mr Gasket, Accell, Lingenfelter and GM racing supplied all the parts for me to build a stdcab Chevrolet pickup that would handle a performance that matched the NASTRUCKs. I pulled the heads for gm racing heads that we cleaned up, port match to tuneport and we pushed about 22lbs but belt slip I made a cog belt system and it made 26 with a Vortech Mondo supercharger, also need stronger valve springs. That 30 years ago we also o-ringed the heads and the block. There was no data at the time to fall back on. We actually broke a few pistons during setups. Oh and we were getting different cams from CC/GM racing. And I remember we also changed pistons to a 7.5-1. Compression
I hope you get the truck dialed in on the track and challenge the old man (old man's garage, bull) to a grudge race. Excellent content for the 2 of you and your both SBC guys.
Eric Can you jack your fuel pressure up to compensate? If no, you'll need bigger injectors/throttle body assembly if you can't change the injectors, or you can do a blow-thru carb. I wouldn't be afraid at your HP level. Excellent results. Should be all you need for a while to go fast as you care to go. Very nice.
Eric says: I just want to go 10:00 ET. Engine says, "but I have the ability to run 8:50 if you'd just feed me more fuel".... I hope Eric gets a bad case of "the drag racing bug", and just goes for it! lol I'd love to see that truck/engine combo run it's true potential!
@@timothybayliss6680 Yep, I've brought the gearing up a few times. Back in the day, my mid 10@130 SBC had 28.5 slicks with 5.43 gears. Ran around 8000 RPM through the lights. I feel Eric's truck is just going for a cruise down the strip to run the times it's currently running, and capable of much, much more. If a stock bottom end, cast piston, junkyard 5.3 LS can temporarily make 1000hp on boost/methanol with a good tune, seems this should be capable of easily attaining 1500HP and still be reliable with the bullet proof bottom end it has in comparison. I'd think 1500HP should put this truck solidly in the 8s.
Love 1st gen S10s my dad had one when i was 14 with a 355 and a 3rd gen Z/28 when i was about 5 or 6. But anyways i wanna build a sreet/strip S10 to daily
The voltage drop is very important running the injectors at full duty cycle. It affects the pump output and the injector response rate. That setup is trying for a massive lean out. Also 66psi? You would be better off plumbing an extra injector into the boost pipe. Very lucky the dyno ramp rate was so quick. As a tuning tool it would have been nice to have the sweep longer to better simulate a drag run.
Looks like it needs some power enrichment (accelerator pump) to get the lean spike out when you first go to wide open throttle. The CL correction will never be fast enough to take that out, and its over reacting to the lean condition causing it to go rich.
I had a customer with a 385 Ford drag car. Hew destroyed a motor due to dropping oil pressure at the big end. Turned out to be the adapter plate for running a remote filter. Changed to a shorty filter directly on the block to solve the problem. I would be scared of running the S10 on the track until you resolve the problem. A 3 second dyno pull doesn’t stress the oiling like a 9 second 1/4 mile pass.
Very cool that should haul... inject some water in it and lean it out a bit to get that duty cycle down and it’ll make it safer ... really nice 9.90 will be a breeze ... great job
Great work. Love the channel in general. Please just take the next statement as a generalized statement not a negative. If that’s a dynocom dyno I’m not a huge fan of that type of dyno due to the way it loads. If it doesn’t create enough load they read high. It’s all up to the user to properly load the car. A dynojet is a very heavy load due to the roller being thousands of pounds. This way the roller being a single weight the control is more accurate when it comes to numbers. However if it’s overloaded it reads lower. Im just not a fan of the way it loads the car.
AFR 11.5:1 on the petrol scale is Lambda 0. 78 that gives us correct AFR for E85 at 7.66 pounds of air for 1 pund of E85, right? 926 lb/hr E85 times 7.66:1 in AFR => 118 lb/min. airflow. That seems like a lot for this hp level. B.S.F.C also seems very high. Do you know if these injectors open 4 or more times pr. engine cycle or something?
Like Eric mentioned, BSFC is higher on boosted engines. Plus E85 has a higher BSFC than gasoline. So yes, his BSFC is going to be very high compared to a naturally aspirated petrol engine.
I was thinking turbo which is lower but with a supercharger you have to account for paracitic loses. Also the heat from that header could be offsetting some of the cooling benefits of the e85, and those collectors mentioned could play a role.
@@stevenbelue5496turbo engines have a lower bsfc than a supercharged engine but its still worse than NA. High compression NA is the best, you get the most energy out of the fuel without spark retard or excessive enrichment.
@@timothybayliss6680 I guess in our modified world that holds true but with oem or atleast the studies ive seen and i searched quite a few after i made that comment the turbo charged engines were more efficient with some as much as 8.8%. Of course that was oem(gasoline engines) which doesnt see high compression NA or atleast not nowhere near what we're talking about.
Currently building a 2003 Sonoma. I’m curious what are the wheel and tire sizes here? Looking for a similar setup, but a different wheel. Eventually I want to back half it. Any modifications to the rear wheel wells to get those to fit? Thanks.
As you've said, you should DEFINITELY go with a Dominator, you've pressed your luck FAR enough with the sniper. There's SOOO much more info, I/Os, options, traction control, injector choices, etc... Plus, You're already familiar with Holley efi software. Don't bother with multiple sets of injectors unless you insist on running 2 separarate fuels at the same time. , which is unnecessary with e85 being as cheap as it is. ALSO, you can run a flex fuel sensor to run gasoline as well. Also, it's common for the brushes in the alternator to bounce at high rpm and cause a voltage drop. Stiffer springs will solve that.
If he goes dominator he'll want to run with more than the port injectors or he will need an intercooler. The sniper blow through is cooling his charge air.
Is that the injectors that came with the stealth? If so if you wanted to keep what you have you can put bigger injectors in the Holley stealth I did it when I had a super sniper. Fic has them.
Yeh, if u went 2 injectors per port, I'd be temped to daul fuel combo like they do at drag week, so the only time you run methanol is down the drags over certain percentage of throttle turns the methanol injectors. But seriously that in the 9 second bracket already on e85 just not super safe at the moment
I have an 85 s10 and getting ready to put a small block 434 what oil pan do you recommend and headers I watch your videos all the time thanks for the advice and great videos
His WBO2 is probably still calibrated for gasoline. That doesn't hurt anything, it's just a different scale. Also, if he gave the actual AFR numbers, people would be like "OMG that's crazy rich" because their brains are calibrated for gasoline.

Even the 3,55 gear and 28" tires at 7300rpm means 8s. Its not geared to trap at 130, more like 155-160.

I have had good luck leaving waterlogged electronics on a dehumidifier overnight. If moisture can get in, it can get out.
That supercharger really makes some good power! Thanks for the video
Good looking truck and runs like a dream
Nice looking truck I been thinking about buying a torque storm as well
Very nice Eric, thanks for sharing.
Definitely makes big power.
Very impressive. 👍👍💯

I agree. I did add some after testing.
Torque Storm is AWSOME. Im installing a kit on a 04 GTO right now
Good hp results, now you just need to translate that into some good 1/4 times.

Thanks for another great video. What fuel pressure are you running? Try adding 10 or so psi to base fuel pressure. Nice dyno numbers!!!!!!!!!
Just saw on data log that fuel pressure is already pretty high.
Eric if you are reading AFR on a gas scale it needs be 11.2 AFR on E85 FYI and look at the plugs

Nice build! Looks and sounds sweet! Should make for a nice streetable track truck............until you step on the gas. :)
It liked that timing! Angry!
Is your truck foe enjoyment of the build and tuning ?? Or do you eventually intend to race at the track. ?? Regularly
I don’t have time to go to the track regularly. So it will go out maybe 6 times a year.

After the log.
Can you bump fuel pressure some?
How much does the sniper support 🤔
Video starts at 0.00. I know of 8 rich people and Eric is 6 of them.......
thats alot of power in a s10 my g body its not real happy on 10/50 tire still its great though 427 w/t nitrous here 82 turbo buick
Why do you run 721? Just curious because my birthday is july21's and I run the same number on a twin turbo s10 lol
Because that was the number of my favorite imca modified racer van gemmel.
On E85 your A/F should be around 8 in boost right ?
