I watched a few SRT6 drag videos linked on this forum where I had thought I had seen the filter removed. When both horns are re-mounted on the driver side, one would expect to see a big filter on the passenger side. It also seemed that "12.2" has become the "holy grail" of 1/4 mile times. I wasn't sure so I shrugged it off.

But when RIOT was the only SRT at the Midwest Drags who ran a "12.2" (there's that number again) and then I was looking at those pictures posted on the MB Forum, I figured that had to be the trick to hit the "holy grail" of 1/4 mile times.

I actually thought that pulling the filter would work - dangerous yes - but effective.

yup exactly like that one. it looks like it owns ALL

 

Yep, I can look at what my gauge reads for the HE coolant and pretty well tell you what the time will be . If I was bracket racing and have my time dialed with the HE coolant at certain temp, I could use my fans/IC pump circuit between runs to keep it at that certain temp. After lunch at the event my temp was back down in the low 90's and ran a high 12.5, next run (just went down came right back up to run again) the temp just broke 100 and I ran a low 12.6. If I had the time I'd like to go to the local 1/8th and see if I could win a little $$, there's no 1/4 mile tracks within 100 miles from me. Personally I think my little set up would work out good at the track as long as I had 15 or 20 minute's between runs to get my HE coolant temp where I wanted it .

 

Try it and let me know how that driver side radiator to headlight clearance works out.

 

More food for thought....

Dyno numbers were provided on the SL55 /NW /BDJ, which proved there really is no advantage between the BIG THREE. Here is a little more information to hopefully stop the superiority complex about intakes available to our community .

NW
1/8 ET- 8.515
1/8 MPH- 90.28
60’- 2.019
Temp- 90

SL55
1/8 ET- 8.506
1/8 MPH- 83.48
60’- 2.074
Temp- 93

BDJ
N/A

I went onto dragtimes.com and searched for an SRT6 running in 90+ degree heat, with only the NW or BDJ intake. I wanted to compare those intakes to my SL55 setup, which is running in 90+ degree TX heat. Finding one running the NW intake only and none running the BDJ intake, I listed those 1/8 runs above. Rob did the NW run and I did the SL55 run, so dyno numbers and track numbers show NW compared to SL55 will net you no real advantage. I’m not knocking the NW intake at all, just providing numbers so don’t shoot the messenger .

 

Thank you for the comparison, it's definitely very helpful. However, wiser people than I always said that the trap speed is the measuring stick of a fast car, and the ET is the measuring stick for a fast driver. The fact that you were able to click off practically the same time while being 7 mph slower (!) is pretty amazing.

I raced more experienced buddy of mine; he was stock, I had intake/exhaust/gears. I put 0.15-0.2 on him in the 1/8th, with 3mph higher trap speed. And I know he was launching a lot harder than I, so he should have easily put a couple tenths on me in the exact same car.

When I see the numbers you posted, it simply tells me that SL55 intake guys are much better drivers than NW guys. j/k

In all honesty, specially with kinda similar 60' times, I'm not sure what to take away from these numbers, except maybe different power/torque curves for the intakes.

 

I was thing the same about the power/ torque curves also.

 

Your right about cooling the temps down between rounds. I don't have any upgraded cooling mods and don't feel I need them for running at the track. I need 15-25 minutes to cool my car down and it flys. I tried something new this time around and it worked out pretty good. I put towels over the s/c and intake then load up the bags of ice on them. Put a big fan blowing right into the motor, with a window a/c unit blow cold air into the fan. This past weekend the hottest run at 103, not using a/c unit yielded me a 13.17. Next pass using both at 98 degrees yielded 12.97, same thing 95 degrees 12.93, 1st round eliminations 93 degrees 12.866 on a 12.86 dial. Took out #1 in points on that run. Kept working and made it to finals of ET points race. Lost in finals because I couldn't cool my car down. A dust storm was coming and ran like 10 minutes after my last run. Car slowed way down and couldn't break a 12! Lost but if I knew my exact temp, I would have adjusted my dial even further. I changed to a 12.98 dial and still ran slower. So cooling is key, for everyday driving yes an upgraded HE would be needed to have the power more available. The supercharger is very picky about temps. Otherwise deal with the heat and be happy. This is my second final round in 3 ET summit points races I've gone too. The most common phrase i get is "Oh, your the one in the Crossfire".

 

Having that HE temp gauge to see where the coolant temp is at is great. It is very accurate too, amg-jerry hooked up his data logger in my car & made a couple runs down the track and the gauge was right on the money of what the data logger said. It's also amazing how fast the coolant temps drop once you start driving the car down the road with out getting into it. I had my car out Saturday for a drive and went past the local 1/8th on my way to where I was going. I didn't know what class was running though, but I came pretty close to stopping to find out . But it was in the high 80's, I would have had to drive back home, put the DR's on and either drive or trailer it back. Good thing I didn't, after my little drive I took it started raining about 20 minute's after I got home. Sounds like you do a lot of racing and pretty good at it.

 

I seen where you installed the gauge and it's looks great. Where did you install the temp sensor for the gauge. I'm assuming before the ic pump. Also do you have pics of that install? By the way love your gallery, you have an awesome layout. Looks like lots of hard work paid off. I do hit the races quite a bit. 2000 miles so far. I started when the car hit 1000 miles and just passed 3000 miles. I don't drive it much for anything else. I can't take too much credit, the car is super consistent and very, very, reliable. With knowing temps I could add it with my et predictor data. The DA for the other night was 4500'.

 

Thanks for the compliments on the layout, it's like having my own mini state forest and my house sit's 500 feet back into the woods. But it's a real pain to keep the place looking good, I work my a$$ off and don't have much free time because of it. Here is a pic of the sending unit mounted in the HE -

And here is the link to the thread of the install.

I also have a circuit built that turns on the I/C pump when I turn on the fans with an indicator light mounted on the gauge. I have it all hooked up so you don't even have to have the car running or even the key in the ignition. Just a click of a little key fob from up to 50 foot away.
