New best E.T. in the Coug

This was on the 12.198 pass; I didn't get video of the 12.179 pass. I wasn't too concerned with getting video last night, so I didn't run a camera in the car this time out.



And the timeslip, a 12.179 @ 113.04 MPH. That was just a little short of a new best MPH for the car, but a tenth quicker than this past spring. Had the track been hooking better (especially downtrack), I think it would have run a new best MPH as well.



Anyway, now it's time to slap the street tires back on and enjoy the car before the snow starts flying.

I'm gonna hold you to that, I'll be looking for that 11 second pass next year~!

You should come down and run with us at Fayetteville. Let Rob & Chung check you tune and dial that thing in right. You'd be running mid-11's in no time and have that 11 second pass before the end of the year!

Congrats Rod!

Run looks good. Need to really get to smacking on those 60 fts! Need to get them down in the 1.5's.

Keep whittling away on them.

Nice !!! I've watched this vid like 10 times since you put it up... lol Your cougar is by far my favorite cougar on this site. You have done a great job with both looks and speed with that beast of yours. I wish I could see it in person... Maybe even a run a pull or two for fun. Hat's off to you sir

Thanks guys. I've only glanced at the datalogs from Wednesday, but I believe that I've finally found the solution to a few long-standing issues that I've had with the tune. I wish I could get back over to the track one more time this year, but that just isn't in the cards. Life just gets in the way sometimes.

As far as the 60's go, I'll keep attempting to get the car into the 1.6's, but the converter is too tight to get near 1.5's.

I'm actually already running a 2:1 drive ratio. You've got to remember that it isn't intercooled. The meth injection certainly helps, but the ACT's are still pretty high as it is. I'm sure I could spin it a little faster to pick up a few more psi, but I'd much rather play it safe.

If the engine/trans ever need to come back out, I'll consider it then.

On the 12.19 pass, ACT's were 154* at launch, peaked at 160* at 5K in first gear, then dropped over the rest of the pass to 138* at the traps. On the 12.17 pass, ACT's were 168* at launch, peaked at 180* right at the 1-2 shift, then dropped to 150* at the traps.

With no bypass valve, no intercooler, and spinning the blower at double the engine rpm, the thing puts out some heat. Back when I was only running 5 psi (without meth injection), ACT's would increase ~30* during a pass, often reaching 200+* by the time the car reached the traps. Now, I'm running twice as much boost and the ACT's are ~15-20* cooler at the traps than they are at launch.

I'm running a 625 ml/min nozzle. If the start and full on injection points are set any sooner then they currently are, it quenches the spark and bogs out. I think it could handle more meth/water above 6K rpm, so I may try adding another small nozzle and backing off the start and full on points a little in the future.

What ratio mix are u running? U need a bypass button so u can spray it in the burn out box to keep it cool, u need to leave the line at 130 tops, that heat is killing you how much boost are u running with the svo cars they usually leave the line under 120 and never get much hotter, the KB makes some heat from the sound of it

I'm running a 50/50 mix of meth/water. The system will kick in slightly in the burnout box with a little pedal modulation, but I was planning on adding a circuit to manually activate the system this winter. The only holdup there is that I need to research whether or not I need to use a diode to protect the controller when I'm applying voltage to the pump. I'm at 10 psi of boost.

I just received word from Snow Performance today. Backfeeding 12V to the controller will damage the controller. I'll either use a pair of relays or a diode to protect the controller when I get around to wiring in a button.

I forgot to come back and update this. I ended up wiring up a relay to run the pump manually via a momentary switch whenever the line locks were engaged, and I took the car back to the track on November 10th. Unfortunately, it turned out to be an 80 degree day and I was only able to get two passes over the course of seven hours (Gateway sucks), but it was still a worthwhile outing. I worked the momentary switch during the burnout in an attempt to provide enough meth to cool the charge as much as possible without bogging/puddling, and the car ran a 12.238 @ 113.58 MPH (new best MPH) on the first pass with a slightly off-par 1.789 60' time. The datalog showed that the temps at launch were cooler than usual for those ambient temps, and that carried over into cooler temps through the rest of the run. On the second pass, I gave it too much meth during the burnout, apparently puddling some in the inlet manifold. It was rich/coughing through first and second before clearing up in third, going on to run a 12.413 @ 110.21 MPH with a 1.750 60' time (second best 60' time).

The plan for this winter is to install a second solenoid and nozzle that will be active when the meth injection is set to manual control. The end result will be two seperate meth injection systems. The usual system will remain just as it is, with the 625 ml/min nozzle, and the Snow controller running the pump at all times except when the line locks are set. The secondary system will be active only when the line locks are set, with a smaller nozzle, and controlled by the momentary switch I already installed. The idea is to dial in the secondary nozzle size so that I can simply hold the momentary switch during the burnout to provide as much cooling as possible without dumping too much meth and bogging/puddling.

Hopefully I'll be able to get the car to the track in some decent weather next spring, and we'll get to see how well it all works.

Sounds like your really over-thinking the Meth injection. It shouldn't be that complicated.

Exactly once the rotors are cool on twin screw it's game on, what I done when I had the roots blower is just keep the rpm up during burnout box, it sounds like with good air and getting the rotors cool to begin with will prolly get you the 11 sec slip, on your setup I'd prolly run a 14gph and 2 or 3 Gph and I bet u could gain even more

If I had that mindset, my car wouldn't exist. It might be a complex meth injection system, but it isn't exactly difficult to implement, and the functionality is certainly worthwhile. You have to keep in mind that it's my sole source of air charge cooling. Thus far, it's helped knock over six tenths off my E.T.'s and pick up 6 MPH. It definitely works, but its performance in the first few hundred feet of the track could be improved.

Exactly. The datalogs definitely showed that spraying in the burnout box worked to drop the charge temps at launch. It was just tricky to judge how much to spray with the 625 ml/min nozzle. Once the secondary system is dialed in with a properly sized nozzle, it'll be simple, consistent, and should help significantly in the first half of the track.

I have run the rpms as high as 6K during the burnout, but the problem is that due to the lack of load/TP, the airflow isn't there to fully activate the meth injection. It would likely kick in if I did my burnouts in third gear, but I'd rather keep it in second.

Why not run 100% meth? It works good in my syclone at 20psi. IAT's about 120 at end of quarter on a very hot July day in S. Ga. with tracks temps in the high 90's. That does require tuning around the meth of course. My AFR's are about 10.5:1 or so (fatter for the meth). I am spraying the hell out of it. I have a Alky Control progessive kit that starts kicking in a 5psi, then ramps up from there.

This is a shot of TunerPro on a dyno pull this summer around June in N. Fla. I do, however, have an ATA intercooler.

I really have considered it, but while it would increase the effective octane, it wouldn't cool as well due to methanol's lower latent heat of vaporization. Plus, I'd be relying even further on the methanol injection system for fueling, which I'm not comfortable with. Lastly, there's the whole flammable liquid in a vented tank in the trunk issue. I do have a rear firewall in the car, but I never want to test it.

It might be a possibility in the future, but I'm not ready to go to straight methanol just yet.

Not to be argumentative, but there are lots of meth kits that have the tanks under the hood. My experience is that 100% meth adds cooling to the system. If you run 100% meth injection, you defiantly have to modify the tune to accommodate for the meth as a fueling source. All is OK unless you run out of meth and decide to ramp the boost up.

Meth, as I am sure you know, allows higher boost levels and more timing. Here is a vid of one of my buddies who has made a SBC V8 running higher boost (20 or so psi) with no intercooler, and only using the meth for cooling. I know he is running E85 and this does make a difference, but, I do run pump gas (93 octane) at safe knock levels at 22 psi and 24 degrees of total advence all because of meth. Also, my truck is a safe daily driver with very good road manners. Please, I am not trying to preach, but running 100% meth is not all that uncommon.

Why do I feel like I have to defend myself around here?

Neibert's '91 got me hooked on the twin-screw, and it's just how it all worked out. The car isn't intended to be a drag car. Far from it. The goal from day one was just a nice street cruiser that could break into the 12's. I'm honestly happy with the car just as it is, but since it's so close to the 11's, I'll keep tinkering til it gets there.

Methanol definitely does cool the air charge, but it isn't able to cool as well as water. It's latent heat of vaporization is around half that of water's. I have thoroughly researched running 100% methanol. I know that it isn't uncommon. I'm just not ready to do so.
