Unfortunately wax won't protect debris from chipping the paint.

...that's not to say my car isn't due for a wash, claybar, and wax. It's so dirty it's a disgrace to my SRT brethren.

You need to leave enough rubber from the burnout-pit onto your fender so any thing you pick up after you leave the strip on your run just hits all the rubber you left on the fender from the burnout-pit.

So
1.wax to help remove rubber
2. melt rubber onto fender to protect from chips... j/k

Glen and I are in line for first round. he ran a 12.19@113 on his time run and I ran a 12.12@114 (going way lean still). Results to come......

Not a good night as far as bracket racing goes! I spun 3 tenths and had the guy on the tree (.009 to his .024)! glen red lighted and went 12.18 on a 12.17 dial. Oh well. I'm done for the night, but glen is gonna give it one more shot.

Ok, we datalogged each car's IAT's last night. Glen registered a high of 154 deg and I registered a high of 165 deg. This is on a cool night as well. So I suspect that the NW supercooler is the difference here? I purged mine so I don't think there is a air bubble in the system. I could be wrong though.......

The two things you will notice with the Supercooler are.
  • Lower IAT, during WOT @ 150ish degrees and around town driving 15 +/- 3 degrees above ambient.
  • Quicker recovery, the time it takes for IAT to settle around 20 +/- 2 degrees above ambient after WOT.
One thing about your fuel issue though, if you add an AFP regulator it will fix your leaning issue on the top end. However, it will make you little miss piggy rich in lower RPMs. Just an FYI ....

What were your temps on your 2nd to 3rd gear shifts? I have datalogs on mine for 3 or 4 runs in a row on the street on 50 degree and 66 degree days if you want to see them. We do not have any straights around here for miles (curves everywhere lol) so that is as high of a gear I can do unless I drive 30 or 40 miles to the interstate.

Did you run octane booster yesterday? It looks like you have your mph back for the most part.

11 degress isn't much, plus you have been running lean so that can also be an issue.

Ran the octane boost, but I don't have the exact IAT in second. It looks to me like its right around 150deg. Also, I just checked it again and I must have missed it, but I reached a 170 IAT last night. Something is up with the cooling system. If everyone else isn't running that high, then there must be something that is causing the IAT's to sky rocket up like that. Like Dave said, it could just be my lean conditions causing this. Down track I'm running right around 12.5-12.8 so.....

I am not sure if this is even useful for you since I was only running the car up to about 70mph. I would say most of the heat is generated on the top end runs at the 1/4 mile track or running the car hard like on a roadcourse.

I will get the rest of the datalogs i did recently if you think you need them.

Are these from start to 70mph hard acceleration? I don't think it matters as just crusing around mine is usually over 100.

Question Re: At the track...

Id be interested in your f/a readings with and without the meth as a comparison, thanks Woody

f/a? let me know what you need and i will see what i have. i datalog all the time lol. the runs above show with and without meth.

i dataloged through several tanks of meth this summer on a 95 to 98 degree day with high humidity and seen an average of 35 to 40 degree cooler IAT temps and for some reason my ect is always a few degrees cooler as well when i use it which is weird. i was testing which nozzle was the best balance of cooling while having the lest effect on a/f ratio. the 3gph had minimal effect on a/f ratio but only cooled the IAT by an average of 15 or so degrees. The 6gph cools an average of 35 to 40 degrees but the a/f ratio is about .9:1 richer (example 12.5:1 to 11.6:1). I think that a 5gph nozzle would be the best but i never got around to ordering one. That was using the nitro/meth/water mix, if i was using only water/meth i would have seen better cooling results since the nitromethane runs a little hotter. The 1/8 mile track results i posted earlier was only using water/meth 50/50 because i only have 1 quart of nitromethane/methanol left and i want to save it for the 1/4 mile track when i go in a week or so.

on my old supercharged tiburon i was able to run 3psi more than what was considered safe on a stock block by using meth for cooling. in fact the car is still running great with 65,000 out of 90,000 aftermarket supercharged miles on it.

The runs i posted show the mph in the first column. it actually shows the timing and kpa but i cut that off for the screen capture or it would have been to big to post on here.

Here are three consecutive runs to 110+mph on one datalog. The meth only kicks on at 9.5psi and

this is on a 78 degree day in May with 85% humidity. The IAT only goes up to 120 one time after i

let off the throttle when the meth shuts off and that is just for a few seconds. These runs

are 100+mph and are one after another and includes driving around and sitting and idling

time as well so this is a good example of how effective it is when you run it directly

through your supercharger. You can run less meth and more water for better cooling and less

effect on your a/f ratio. It just depends on what you want the alcohol injection kit to do.

Mine is on a switch so i can turn it on when i want to use it and off when i am done. I did

contact the manufacturer of the supercharger and they confirmed that this will not damage the

coating on the supercharger.



Pay attention to the throttle position % and mph and you can see that anytime i am on the

throttle the IAT is nice an cool. When I let off the throttle after the three 100+mph runs

you will see it shortly climb to 115 or 120 degrees then drop back down.



This is on my old tune and before i separated my engine coolant, the jury is still out on my

updated tune and i now have the coolant separator mod.



I pick up a peak average of .9psi consistently with the 6gph nozzle.




You can double click the video to watch it in HQ if you can not see it clearly on the forum.

Thanks for the datalogs. Seems like IAT is changed on every 12th reading. Values would be even more accurate if IATs would change at every reading from the OBD-port. Thanks.

A great tip I learned years ago from an old drag racer: Before your burnout, rub Vaseline where the rubber sprays up on the rear quarters. Comes right off and as long as it's water-based it won't harm your paint!

Tonight we go! New fuel filter in (the old one had black crap pouring out of it!). BAP in and working so fueling should not be an issue. New tunes by Jerry to try. Temps will be in the 60's, humidity will be low and DA will be negative. 11's for sure tonight!
