After tasting the "sweet nectar" of the Haltech, Torco, and Meth injection with the Billy Boat X pipe and ported TB, I broke down and decided to tune.

I've got 3000 Hard/well broken in miles with a few oil changes on the car, and the motor seems nice and strong, no oil burning. I've got two road course days under my belt as well. The Granatelli expansion tank and custom additional radiator I did with spal fans for the extra fluid is working well!

Before we tuned, I grabbed the 15% overdrive Main Dampner from Howard at Redline Motorsports, decided to change that out rather then the upper pulley. Thank you VERY much for your input Howard, it was VERY helpful!!
I also added the rest of the Billy Boat Fusion Exhaust.

While the weather was hit or miss today, I did get to put my foot into it a few times on the way home, it PULLS very Nicely!!

The blue graph is bone stock, 91 octane fuel: 481 RWHP 565 RWT
The red Graph is stock with 91 mixed with Torco: 546 RWHP 581 RWT
The Black Graph is with all the above mods tuned on Alky Control Meth, 91/Torco: 660 RWHP 692 RWT

Nice! Congrats!

Coming to shift sector 2/25? I'll probably bring the Z06 out along with our M3 and M5.

Thanks, not sure yet...

Nice numbers!!

SO thats still on the stock manifolds with just the off road X pipe/cat back? No larger reservoir or heat exchanger?

Basically just a Halltech, 15% pulley, meth and X pipe.

Pretty killer numbers, especially for no headers.

No knock?

Great work! I plan to put my Z under the knife this summer (if it doesn't sell).

Bob U

Impressive numbers.

Could one do such a setup but without meth? Meth just seems like this thing that I know nothing about and not sure I'd want it on my daily driver.

Nice numbers!

Best,

Very Nice!

Was shocked about the difference between Stock 91 octane and Stock 91 with Torco. That is huge. Glad I can get 93 in my state.

stock, 91 octane fuel: 481 RWHP 565 RWTQ- Does this seem really low for stock numbers?

0Terry@BMS

It's not a dynojet so the numbers themselves are not overly relevant. The delta is. That is a huge delta, but 91 octane is really bad. I tune on it regularly and these numbers don't surprise me at all.

I amended my post, yes, I've got the Granatelli expansion tank, and did a custom install of a second radiator in the front driver's wheel well with 2 5 inch spal fans for the extra fluid.

No KR, but we are running PLENTY of fuel, always mixing 11 to 1 with a can of Torco, just a nice amount of progressively delivered meth under boost, and all stock timing. We also pretty much left the stock tuning safe guards in on temps, since they don't really pull too much on coolant. Julio at Alky Control and I are testing his kit on a new aspect, He'll jump in on that...


I've been running Meth on my other 2 cars for many years, over 10 on my 98. It's really no big deal, it pretty rock solid on the delivery, and only comes on with boost.

jbsblownc5

Yes, it pulled 5 degrees of timing, really made a difference.

It says in the owners manual for the 17s, use 93, or you will lose performance on 91. With 93+ (Torco/91) we made normal #s, 546 581...

I hear you Terry, but again, on this Dyno, once we dropped in the Torco with the 91, we ran normal #s for stock Z06: 546 RWP 581 RWT

0Terry@BMS

Yes I'm sure the dynojet numbers won't be that different. 15% overdrive + meth + torco + tuning is a solid combo. 140mph or bust!

eddie-d

Those are truly substantial gains. I too was surprised at how much of a difference Torco alone made. Like Gene, I would have liked to have seen numbers without Meth. Your improvements in HP and TW are making me reconsider the idea of tuning my Z. Perhaps a silly question but has the everyday drivability been negatively impacted?

jbsblownc5

Thanks again Terry, but let's lose the word bustlol

I've done runs with and with out meth on another dyno, and other then A/F getting leaner, it did not change power levels...

As far as driveability, I have to say it is actually MUCH better then stock, no more lag, the car responds when you hit the throttle, and it drives perfect.

ACS55

Looking awesome!

I am dying to see what that thing ET's and MPH's!!!

Bob U

91 plus Torco made an impressive gain, do you think there is additional power to be made by adding Torco with 93?

Bob U

Did you make any improvements to the stock supercharged cooling system?
I see that you added expansion tank and a additional radiator, is that for the engine cooling system or the supercharger system?

Also, are you using a different temperature thermostat?

jbsblownc5

While I'm not a huge 1/4 mile guy, I'll certainly get to the drags, as well as the 1/2 and standing mile this years...

Here's my take on gaining power by using Torco and 93. On the dyno, and as long as it's "good solid 93 fuel" I don't believe much would be gained by running Torco, under the assumption that Chevy's tune is dialed in at 93 octane.

I will say, that on the road course, or a long hard canyon run on a hot day, having any kind of extra octane in the tank will help you "maintain" optimum HP. As things heat up, it's easier to detonate, and have the computer pull timing/HP, and therefore having more octane will stay that off...

On the other hand, if you add Torco or mix in some 100 octane fuel with your 93, and then tune the car at that higher octane level, YES, you will pick up HP.

In the case of the 17s, as previously mentioned, Chevy tuned them on 93, so by simply raising the octane to at least 93 by using Torco or some other proven means, the computer won't pull the timing on the dyno, hence the added, or actually lost HP comes back to stock levels...

The added Radiator with Built in Spal fans is for the Supercharger cooling system. I have a 17, which came with the second coolant radiator already in place. I do run 40 Below coolant additive in both systems, as well as diluting the amount of actual coolant.

I have not changed the stat at this point, but did slightly lower the temp at which the fans start to ramp up, thereby keeping coolant temps just below the point that the computer starts pulling timing.
