Finally got my car on the dyno.
Car feels completely different in all the best ways. I spent months I stalling everything and heat wrapping everything nice and neat.
Pray ported MSD
LT5 TB
Rotofab dry
DSX FF
TSP 1 7/8” coated headers with HF cats to MBRP race back
Taylor wires and NGK LTR6IX-11 plugs

Did 463whp 445tq on 91 and 480hp 463tq on E48.
I fuged up and didn’t run the tank low enough before to get enough E85 mixed in.

Curious what y’all think numbers would be on a full tank of E85 pump?

I'm no expert nor even close but that seemed like a HUGE jump on E even if you was on 85%.
Nice numbers though.��

Nice work!

I would not expect much more power on full E85, maybe another 5 HP. Most of your timing benefits are all in by E60 anyway.

Thanks man. It’s been a journey. I’ve had most of these parts plus a slew of BMR stuff laying around for about a year. Just happy to get it all together and running right.

Yea that’s what my tuner said. He thought about 490. I think a lot of it had to do with the MSD. It has a pretty heavy porting job on it. Bought it used from a guy on eBay for pretty cheap. Dude had drilled out for port injection and did a terrible job epoxying the holes back in. I spent my weekends fixing those and cleaning up the ports with my Dremel.

Honestly there isn't a lot of gain in power once you get over E40. The exhaust smells better when you get to E60 or higher. I see NA applications pick up like 5-6whp from E40 to E85. Most NA LT cars see a 20-25whp gain on full pump E tops if the 93 tune is on point.

Not going to fight for another 5-6whp gain if that’s the case. I’m probably done with power mods until I decide to crack open the top end. I will probably lose the MBRP set up and go back to a NPP set up from Corsa. This thing is insane loud. But with the baby coming it’s probably going to get old fast. Maybe an ATI damper before all that.

You don't have to change anything in the tune for the increased E content. Specific tables in the ECU should already be populated up to 85% E. The next time you fuel up with E the content will increase and the tune will adjust and you should see the gains.

The Corsa NPP is amazing!

You know, that’s what I thought. I got caught up with the numbers while emailing with my tuner. I had the car trailered to him as I had to work that day. Funny I never actually met the guy. But he is a very popular tuner here in the north Bay Area.

Ye at the time the MBRP was my first mod and I didn’t want to spend 2k on exhaust as I had just gotten a divorce and the Camaro was the only thing that survived the asset split lol. Sounded amazing with the stock headers and cats. Sounds incredible now with the headers but I know I need to be able to keep it quieter if I’m cruising around town or early in the morning.

keep in mind that you are talking 93. Unfortunately he shares the same supply of Cali premium fuel being 91.... so maybe a few more whp?

I see you are in the same commie jungle of half wits called The Bay Area as I friend. Just FYI there are a few select gas stations around that have 100octane. A few gallons mixed with 91 does wonders.

I think that jump is pretty close to what most see. Mine made about 25 more rwhp with the additional of E85 (E70). I do love the smell compared to 93 octane.

Are you using a Pray tune or tuning yourself? What was your AFR on the dyno on E85 compared to 93 octane. Those are real nice numbers.

I wasn’t at the dyno when the car was there unfortunately. I had my car picked up on a return trip flat bed. Had to work 😢. I’m going to email my guy and ask him. Wasn’t tuned by Pray but my MSD is Pray ported and it’s definitely his more aggressive port.

I’m going to run this tank down and fill it up full E85 and see how it runs.
Funny before I tuned it, it smelled like straight gas. Wife hates it but I had major nostalgia from when I had my foxbody
