Yesterday I went to the drag strip for the first time with slicks on my FBO GTR running 93oct and water-meth injection. My best on drag radias was 10.35@135mph with 1.61s on the 60'. I was ready to run faster times on slicks.

First 2 passes sucked. Worst than my previous passes on DR even while I was cutting faster 60'.

Third pass I improved to 10.29@136. Not bad, but still slow considering I did 1.46s on the 60'. I was a bit disappointed.

I self-tune my car, but I lack "track experience", so I got in contact with one of the top tuners in my area and he gave me some hints that made a huge difference!

After dialing in his suggestion, next pass i ran 10.14@136 with 1.40 60' . I was extremely happy with those times, considering I was running a cheap e85 equivalent setup (93oct and water-meth).

We decided to do another run with lower pressures in the slicks, and a higher launch rpm.
With those small changes, i was able to pull my personal best by cutting a 1.37s 60' and running 10.09@134.5.

Things I learned yesterday:
1. Just throwing in slicks will not make you faster. You need to make adjustments to make use of the added traction. I was under the impression it was going to be a plug and play thing.

2. Knowing how to tune your car to make HP does not means you will be faster than people that do this for a living. If it wasn't for the help I got from a real tuner, it would had taken me several visits to the track to figure it all out. A waste of time and tires :)

3. Driving with stock front wheels and radial tires (Hankook RS3 in my case) gets a bit scary close to the 1/4 mile. With front tires pressures at 22psi is less scary, but you can still fill the back "waving" as you get close to the finish line. Its manageable, but scary.

Nice work!

 

Do you have some info and pics of the meth injection kit you have setup?

Im using a Cooling Mist kit with some improvements like braided lines and aem filter. The only complain I have with cooling mist is their jets. I had a hard time getting two of the same jets to deliver similar cc/min (had to return them several occasions until i got two that were close enough) . Ill share some pics later.

Meth injection is fun I used it on my boosted Corvette.  Only issue was once it's out you're out.  At least on E85 it's 24/7 until you run out of gas.  Seems to give similar gains to what an E85 setup does at FBO.  Kudos for giving it a whril.  The LSx guys typically run 100% methanol without water...maybe give that a try?

+1 used it in my blown vette too. Much prefer E85 personally.

e85 would be a better and safer option for sure. But I don't have access to e85 at the pump. I can get it from speedshops (sunoco or vp) @ $14/galon.

Since meth is risky to run, I always keep an eye on datalogs to make sure of three things:

1. fuel duty cycle remains close to expected values (i use old datalogs to compare). An increase in fuel duty cycle could indicate that the meth pump is going out or that jets are clogged.

2. Compare fuel ratios between banks. Differences could indicate that a jet is clogged.

3. From time to time, i check the the jets are providing the expected cc/min and that they don't differ much one from the other

A pain in the butt for sure when and definitely not for people that want the "maintenance free" performance e85 provides.

Here are some pics. Don't mind the ugly shipping paper, I use it to spot leaks if they ever happen. So far, the setup has been leak free for years:

I had my tuner back on the LSx platform set up a bunch of fail safe situations that if the meth pump failed or wasn't delivering a certain amount it would put the tune into a limp mode.  You could floor it but the car wouldn't go very fast.  I know for certain the GT-R's ECU is much more complex than the LS stock ECU so I'm sure certain parameters could be set as automatic fail-safes.  I'm no tuner but I'm certain it's "do-able."

Well done..

Awesome time..just a quick one to consider..I also ran water/meth injection...used 50/50 water and meth mix..and I was on full ethanol..my purpose for the watermeth kit was solely for cooling as I did not have a cooler fitted..I see the pics you posted..my jets were much further from the sensor..don't you feel yours is a bit too close to the sensor and throttle...

All the reference I found mentioned that the jets needed to be about 6in from the TB. Which makes it be close to the map sensor.

Probably father down would be the best to get get better atomization and to get more accurate temp readings in a SpeedDensity setup.

Definitely don't do this. It would absolutely provide great performance but 100% meth is way to much a safety hazard to take that risk.

As long as you're safe with it and it's behind a firewall it's a non-issue.

I really doubt I can run 9s without some weight reduction. I was looking at the 1/4mile rankings, and it looks like getting faster 60' feet will be very very hard to achieve. Best 60' i saw in my category (stock turbos) was 1.38 in a 9.5sec car.

It would be awesome to run 9.9s with 93oct and meth

Let's see if I can make it next year

I believe MH has a new 18in slick. Those on 18in Enkei wheels would definitely help you
