Speaking of that car...........I have now added dcai, tweaked intake manifolds, along with my other mods, and have now tuned for my own 100 wet shot system through EC. Just put car on Dyno and hit 450whp and 489 ft/lb torque! Right around the same number Dahiti had with the 150 shot. Track was crappy Saturday with dirt blowing everywhere. Got one run before shut down and pulled a 12.07 at 5400 with a 1.8 60 ft and a trap speed of 118. 11.7 afr with 100 shot. I coming too!

Whose car was on the dyno when that snap shot was taken.....just saying.

 

Impressive numbers, even with your elevation you should hit 11.7 sec no problem.

 

Meth injection has so many benefits. If you tune the car like it's going to run on race fuel, then add safety measure so that the only time you get race gas appropriate boost is when meth is flowing well, ( no holes in the lines, no kinks, leaks, or empty tank) it shouldn't be too hard to figure out.

On the bmw TT 3.0 Liter platform, we could take a safe 14-15psi, and boost it to 18-19 with little or no risk of detonation.

Methanol also brought intake temps to ambient temp so benefits there as well.

Finally, it kept manifold squeaky clean! We had direct injection so carbon build up was a problem so anyone tuning that car that wasn't using methanol injection, wasn't really serious about getting the most out of their car.

Because fueling was a concern when adding so much boost, the methanol would provide additional octane to make the fueling part of tuning a bit easier to manage.

 

I ran water meth for a while. I would vary the mixture to get the AFR's where I wanted them. I could lower them around 1. The system worked great until it "didn't". The boost controller failed and the meth tank emptied into the intercooler while I was in the burn out box. (spraying in the Y pipe) Unless you tune for the meth you will have to adjust quite a bit to keep the power you already have. I did a day's worth of pulls on a dyno to adjust the volume and activation points. In summation, get the best fail safes you can, you'll absolutely have to tune for the meth to realize power gains. Not to mention, I didn't see more than a few degrees of difference in the IAT's. Yes, when spraying through the supercharger it felt cool but the IAT's hardly changed. Spraying in the Y pipe was too close to the sensor to know how it was cooling. The sensor was giving readings identical to before the meth. I'm far from an expert on the stuff and wasn't willing to keep experimenting after almost blowing my engine. The kit is still in my car, just disconnected so if you figure it all out and have great success, I'll fix it and copy you.

I have an extra progressive controller. It's just sitting there. Looks like you had your system blow all your meth in correlation with your fueling. This is not optimal as when your revving in the box, your spraying. Burn out at stock, then turn your system on. If meth spray is correlated with boost first, fueling later, then this shouldn't happen.

To keep things simple, I'd spray into the cold side pipe of the inner cooler. The only temps that really matter, are the temps at the manifold. I haven't mapped out the induction tract for the SRT-6, but far from the TB as possible, Close to the IC as possible.

Next id figure out how much boost the SRT6 can manage on 106 octane.

I would tune for that and ignore AFR because O2 sensors (on my old car) didn't read the methanol as fuel. Is the SRT6 open loop or closed loop fueling??? (adjust fuel injection based on AFR readings = closed loop.

Finally, I'd set meth to inject at 60% capacity at 75% of max stock boost. (16-17 psi is max) so Id start to spray around 12 psi.

Set the controller to spray 100% capacity at 21 or 22psi (rentech kit max boost)

Safety would meter flow at nozzle and when flow is not to spec, then boost controller (ie tune) would only allow for stock boost pressures. When flow is at spec, tune would recognize this and allow the system to keep pushing the envelope.

Next, a float meter, or a monitor for the meth tank. When the tank get below 1/4 tank, the system would only allow for stock boost.

The practical application becomes tricky when you change out the size of your pulley. ( we didn't have a pulley in our applications so we just had 2 turbos that would blow as hard as you ask them too. ( when I got out of that car, we had just had a company redo our turbos with bigger fan blades..... essentially more boost with the same input to the turbos (similar to having a smaller sc pulley).

If there is a tune that adjust for the smaller pulley already and there are maps for pump gas and race gas, with just a little tweaking, we should (at this forum) be able to produce race gas results on pump 93. Also the lower intake temps often tell the motor that more boost is ok. A colder range of plug would benefit and any nos use would be magnified as well.

Cold air intake won't be necessary, a short ram air intake would reduce any restriction.

how does that sound???
