I just hope when I put the Code3 mid size pulley my IATs don't go up. With my isolated intercooler system and secondary heat exchanger I was seeing 105-113 IAT at WOT on a 95 degree day. 160 is high and it was only in the 70's the other day. You definately need to look into a new heat exchanger/isolated system. Or just spray a little N20 to bring the IAT's down.

Yeah it would be best to wait a couple weeks like you said. So that makes what 4 or 5 of us? Should be fun.

 

That is some interesting info. I would be curious what my car logs with jut the code 3 pulley and no heat exchanger.

 

Sometime before summer I'll go back to the 93 tune just because I plan to drive it more. It's officially a daily driver now. Today I drove it in the rain with stocks on of course. Only the 2nd time the car has been hit by rain since I've owned it. Now onto IAT's I don't log those, but would like to. I go off my needle and rarely hot lap. My problem is I can only log at test n' tunes, data loggers are illegal in my class so I don't use it in competition. I wouldn't do any cooling mods just yet. Just lay a bag of ice on the supercharger or spray chilled water over it. It cools in 10-15 minutes. At least good enough for the strip. Still stock plugs and wires too. No exhaust mods either.

 

Thanks for the pic's and the write ups. Very interesting reading. Trying to learn from you guys and get mine out to a track soon.

 

You got it BigKid. with all your mods, you may well be in the 11's!

 

Looks like you had a good time. Nice cars there. I wish I could have made it.

Scott, how did you like your slicks? Did they hook up as you were hoping?

 

They hook up real good, I just need more practice launching with them to maximize their potential.

I thought I would post my time progression as I have added mods to the car. I have been keeping a spreadsheet of my times at the track. You can see all my times, the temps and the mods on the car at the time.

 

Great information. It is interesting to see the progression. Did anyone mention what psi to run the slicks? I am sure you will break into the 11's before too long. I wish I had kept track to that detail.

I was running them at 22lbs at the track. Used my handy Crossfire air pump to fill them back up to 35 for the trip home.

 

Nice spread sheet with very detailed info. Thanks again for sharing.

 

I’m not knocking your times Cruzin because you did run them, respect; though your no closer to stock than me. I say this because you race with out your grill, on DR, on a 100-octane tune, with 100-octane gas, a mod y and manifolds. Then factor in icing the S/C, which is like icing the S/C when on a dyno for better numbers. I race with my grill, on street tires, on a 93-octane tune, with 93-octane gas, stock y and stock manifolds. Then factor, I never ice down the S/C. I have stock plugs and wires (for now) and a stock exhaust.

The more I look at temps with my 181, the more I believe cooling mods are a necessity. Specifically to limit how high temps rise compared to stock, S/C, or 178. As SRTpowa stated, he was seeing 105-113 with an isolated system in 95-degree heat with a 178. Where I’m seeing 160-170 in 70 degree weather with no isolated system, even with one I don’t think I’m going to see 105-113 under WOT. Just last night, it was 58 degrees and under WOT I hit 145 degrees.

I’m curious to know what your average ET is and not your best. Again, not trivializing your accomplishments at all, rather piecing the puzzle together. Please correct me if I’m wrong…

 

I think with a 178mm and WOT it is impossible to get IATs of 105-113 Degr.Fahrenheit, even with a split IC system,CM30 and LET HE ... IATs must be higher in my opinion.

 

That's a real nice break down. I sometimes wish I wasn't so lazy and took the time to log info. I rather just throw it all together and then make my adjustments. Anyway looking at your times with the drag radials has me wondering about the HS converters. It seems you can over power the drag radials from take off, wouldn't a HS converter just make take off's that much worse/harder???

 

Those DR's can take more than I was giving them. I was trying to figure out the "burn out" routine but I think the Stall would not overpower the tires.

 

When I have a little free time, I plan to go back and log the DA for all the runs. Cruzin has got me on this kick and this is something I have never looked at nor kept track of. It should be interesting and I will post the results.

 

Your right without the mani's and ypipe I don't think I would have broke in the 11's. They really made the most difference. The tunes were a little different. The 100 tune definately woke up the mani's and ypipe. I was surprised how different the car felt. I still feel this combo in negative DA is good for 11.7's. or better.

The 93 tune was pretty impressive though. With DA no better than 2500' I would run 12.0's all day. 11's would be possible but not with my DA. My best of 12.02 on the 93 tune was with stock mani's, and ypipe. Just tune, pulley, and intake. I bracket raced a big race around the time I just got that tune. I used a 12.01 dial because I was so close the whole day sub 12.05's.

The drag radials help a great deal balancing the consistency when the track isn't prepped that great. Or the left lane is worst than the right, and you get bumped to the left lane for 1st round. For bracket racing a must, for test n' tune and not going for a pb, not a must. In the beginning I would swear it wasn't possible to get a good launch with street tires. Now as well as I know my car and the launch, I'm pretty sure I could lay down 3 passes within .05 of each other with my stocks. With street drag radials like the nittos, I'm positive I could get into the 11's with DA of 2600' or better. I still call those street tires because the compound is not much softer than stocks.

I only ice in the summer when it's over 100 degrees, and only when bracket racing. The whole winter when hitting all my PB times, no ice was hurt during testing.

The grill is no lie, it does give an advantage. I'm sworn to it and have seen as much as a tenth decrease in times. Now that's with a NW intake, I doubt you will see the same with the SL intake. It may be worth a try though.

My point about being stock is that even with a 100 octane tune the cooling, ignition, and exhaust is more than adequate.

 

Here check out my video its a small and simple burnout and the same procedure I use every time. I always do the dryhop afterwards to make sure they were heated up enough.

It will help explain alot. There could be 2 identical days of 70 degree weather and you run slower than before and wonder what went wrong. This little device helps me keep data and keeps me from guessing why the car is slower. It will give you DA conditions to the minute.

Thanks Cruzin! I have updated the spreadsheet to include DA. I have replaced the original one with the new one in the post above.

 

Awesome I need to do the same, but I have over 300 timeslips. LOL. Looks like November is your magic month. May looked great too. Yes, I'm jealous. Great job.
