Revenge of the Redeye, 9.85 136 Stock Boost, 9.18@149 Blower Only-OLD HEMITUNER REDEYE

[Hemituner]

Over the Winter a storm has been brewing. After 3 years on the NHRA tour I was excited to get back into racing myself so I ordered my Redeye in June of 2018. In OCT I tuned my first Demon and right away noticed it was different enter Tim Barth. Tim and I have known each other for 10 years. We reconnected in OCT after I reached out to ask if he had seen what I was seeing on the 18 software and the rest is history. Very early on I was clear I bought the Redeye for one reason only and that was to be my R&D Mule at the track and to go faster and quicker than the competition. I soon found I didn't have to Twist his arm too hard. I am Fortunate to have quite a few tools at my disposal and we dug in right away as I waited for my car to arrive. Low and behold in Jan the day finally came. We had a plan in place to really go after it at MSHS in Georgia but the weather did not cooperate so we would have to wait. Next stop Rockingham and after spending all day Friday in the rain at the rental we got to work both never having one on the dyno. Saturday was perfect and once we had our baseline of 10.54@131 we went to work and we couldn't be happier. We made about 8 runs on the car and ended up with a best of the day 9.85@136

3) Bogart Front Runner with MT 28x6x18 Sportsman SR
4) VP MS 109 Unleaded Fuel
5) Hemituner Unlocked PCM with Custom Hemituner/Barth engine and Trans calibration..

Fast Forward to 4-8-19, After being accused of not being on stock boost for the 9.85 Tim and I were reviewing data and he made the comment of imagine what this thing would do with a Pulley swap and Ignite so I though why not. I made a few calls and set up a rental at Atco. With only 2 days to get it going it was all hands on deck and Jim@Truestreet Performance was happy to jump in and help. Jim, Myself, Paul, And Tim all got to work by installing an ATI overdrive Balancer along with a Griptec 2.75 upper pulley and a set of ID1700cc Injectors.We finished Wed eve and with a quick collaboration on a starting calibration we loaded her on the dyno only to get 2 quick pulls in before loading her in the Trailer boy were we suprised. The second pull was still rich and we put down 933 WHP on my Dynojet, we unstrapped it and packed her up for the big day.
4-11-19

5:00 am Headed to Atco Raceway.
8:00 am Unloaded and prepped the car by 10 AM we were ready to run. First hit absolutely blew the tires off, I was able to chop the throttle and make a run to get the data 9.7@149.70 was the trap speed we were all blown away. Next pass WORSE, Spun hard chopped it twice and went 10.06@148 clearly this wasn't going to work. Back to the Laptop we go with some launch control Ideas we had been tossing around. Loaded her up did a big burnout and BAM 1.42 60 foot 5.93@119.86 to the center and 9.213@149.61 in the back the excitement was off the chart. Back to the laptop I went still too much power on the launch dialed her back made another hit and BAM 1.343 60 5.891@119 to the center and 9.187 149.13 in the back, Still spinning back to the laptop. Load her up BIG burnout past the tree backed her up and BAM 1.29 to the 60 foot clock 3.744 to the 330 and right before the 8th on what could have been our 8 sec run BOOM bye bye belt tensioner ending the day. Mod List for the 9.18 is below

Brought this over from the other site. Old news but worth the effort at the time. In the coming weeks I will share what we learned!
Thanks

That is awesome. I have question regarding the "stock boost" that I see people claiming. If your running race gas with a tune your making more boost then stock correct? So how come people keep calling it "stock boost"? Is it because it doesn't have a pulley? Still the car is making more boost then stock right?

Awesome 👏

Stock boost is a simplified way of stating the car is stock engine and blower down to the pulleys. You should be able to swap any stock blower off of FCA's shelf onto the car without altering it and the car should produce the same boost at any and every RPM reference point- all other things being equal. The fuel used does not directly affect boost.

Im not going to beat to death the stock boost issue as this is a point of varying opinions that I respect. One thing I can say is the 9.85 passes were done with a 100% unmodified powertrain mechanically. It was tuned and it was on ms109 Fuel.
Hope this helps

I like the info AJ mines running 9.4 with Trans issues kinda gives me an idea of how well my hellcats running ands it not a redeye 👍 good info as for the motor going bad it’s something we all risk when modifying theses cars and pushing the limits

I will go on record that I truly believe that anyone making over 900 WHP on the stock engine is out of their minds. Blind faith will get you killed.
Thanks

Mines stock but I’ve never dynoed it so I don’t know the horsepower it has but probably not 900

Is that for number for both Hellcats and Demons/Redeyes? What would you say is the safe number? I plan on modding my Redeye but I want as safe as possible.

Good thread.

AJ if you could chime in in this I’d appreciated the input , I have considered pulling my engine Down and upgrading the internals with the rod and piston upgrade that HHP has to offer , you spoke about having a horsepower loss on the redeye motors but of course never mentioned what the cause was , is this something I would experienced with my upgrade???

Well then.

From what I have experienced it is all about piston design, hone, and attn to detail on assembly. Save yourself the trouble and at least get a shortblock that is already assembled. So far the ones I have been keeping in stock are very repeatable. I have the latest version going together now for testing.
Hope this helps
