Finally made a pass at the track with my 305 45 17 MT et street R tires. Aired down to 19lbs before going up and doing a tire clean and burn out after pulling out of the water. I am currently at 440 rwhp , with no headers, borla S axle back, LT2 intake, E85, 180 stat, very conservative Jannetty tune , I have lightened the car by 75 lbs, and running just a touch under 1/2 tank of fuel. I purposely had to feel the bite off idle before I went to wide open throttle. I really wanted to just flat foot it off idle but wasnt sure how good the bite was going to be and didnt want to spin. I think a flat foot off idle would have netted me a 1.70 60 ft instead of the 1.79 60 ft I accomplished and netted me a pass in the 11.50s. This is a LT1 base car, no magnetic suspension, so I ran in sport mode and two taps on the traction control button. Considering the 2100 DA hot humid day and putting down a 11.60 flat and 120.7 mph ....I feel good about all the little tweaks finally coming together.

Very nice run. 120mph in 2100DA is good. Next time put it in Tour mode . Those MT’s will always hook. I was running those in my car and they were still dead hooking after 50 passes.
I also have an LT1. Flat foot it off idle in Tour mode. Tour mode softens the suspension and increases weight transfer . Try removing your front sway bar and belly pan for better results.

My car is a base LT1, no options other than a $100 split spoke wheel option so no suspension adjustments. I use sport mode to get max activity from the 10 speed auto. Aluminum belly piece and sway bar off already. My post indicates why I did not flat foot the car off idle, I had to feel the bite first to get my confidence and flat footed the throttle immediately after that. I was pleased with my result never the less and decided as I have many many times over the years, when I get a decent pass, and that usually is the first one, I quit. Its my signature amongst my friends for me to do a single pass if its a good one with no errors. No vibrations, straight as a arrow from start to finish

Congrats on beating your stated 11.8 goal. Looks like my jacket warning was for good reason, because looking at that timeslip tells me that, even in the crappy DA, your car could have run under 11.50 sec. I'm saying that because your car could have run some 1.6 short times IMO.

I was thinking of you and your comments after I made that pass. All I needed was a low 1.70s 60 ft and would have been in the 11.50s instead of the 1.79 60 ft I achieved. But I was so satisfied with the pass and knew there is a 11.50s pass in this car easily I decided to not run again and the heat and humidity was getting to me. Another thing about Lebanon Valley, I am pretty sure they do not enforce that jacket warning, but thank you again for the alert and thanks for the encouragement.

Really good outing I'd say. I'm right there with you on MPH, my Lt1 Seems lazy thru the 1/8 and does pretty good on the back half. I was running in a little higher DA and heat but I was at full weight. Your numbers are dam good for your mods. Congrats. I think next time out I'll try and bring in somemore timing down low to about 3000 rpms and see if it will pick up my 1/8 mile times. Where did you pull your weight? Rear seat cause that's about 58 lbs if I remember correctly. Plus you should have lost some from going to the 17s in the rear. Job well done.

Thank you bud. Rear seat is only 28 lbs, truck floor covering, trunk trim panel against the rear body panel, Borla S mufflers maybe 10 lbs lighter, all plastic off the engine, rain tray under the hood heat extractor, all plastic under the motor up to the front bumper, the aluminum belly piece, front swaybar, w/s washer tank removed and of course no washer fluid now, no front marker frame , rear wheels /tires 6 to 7lbs each , w/shield wiper arms and blades nuts damn close to 5 lbs for the pair, front floor mats out, and thats not figuring half tank versus full tank of gas. I picked up a full MPH from last year when I ran in less than 1500 DA @ 119 .4 mph . My mods after that included (smoothing out) the entire intake tract for any restrictions , putting in the green filter in the already my moded factory air box, replacing the rubber intake bellows with a smooth hard plastic piece from one of the cold air intake companies and running almost 1/2 quart less oil . Last year better DA but was running a full tank of fuel so maybe 50 lbs heavier and the heavier rear tires.
The 1.3 MPH gain in the heat is telling me I may have done a little something right.

Sorry, I was thinking of the passenger front which was the weight on my 16 1ss. Yep 28 sounds just right. Mine weighed about 3625 on the Scales at WWT raceway yesterday with 3/8s tank and full interior. Last year my C7 weighed 3374 with driver and I sure feel that extra weight thru the 1/8 mile for sure. This car feels like a pig compared to it, we went 10.90@128 1.56 60ft and 7.02@102 mph in the 1/8. Kinda wish I hadn't sold it now. Oh well wanted another Camaro.

NP, wouldnt take much to get your car into the 35 hundreds. I hear ya on the C7, I had two, a 2015 base manual stingray, on the the stock runflats and a Jannetty conservative tune only, I ran a 11.7 121 mph speed shifting and not using no lift shift and a 1.97 60 ft

[laynlo15]

Heat really killed it but I'll work on the tune for the next outing. E85, Roto Fab and Drag Radials is all I've done. I had MSD, 95mm Tb, long tubes, expipe and E85 on the C7 so I really can't compare the two. I'll probably add some timing on the launch to get me to the 660. Weight is the big deal as the Vette was 440 lbs lighter with me in it. That's a bunch

It's the stock trans tune limiting throttle.

So what did you run on that hot day ? and getting back to the Vette, was it a manual or 8 speed auto?

King, I know you directed your comment to laynlo and that I also have seriously thought about the TCM from Houston House of Power based on everything you have said about it and the things that can be done. My hold back is because my 2021 LT1 is my daily driver, which has 12600 miles, AFM tuned out and I am totally satisfied how this car shifts in touring or sport, there is no track mode. But it does go into performance shift mode when I start playing aggressive on the street so all is pretty damn good about the 10 speed auto. I am afraid of not getting someone to be able dial the car in on the new TCM. I know it would take multiple trips back To Jannetty Racing 1 hour away. . I have the HP tuner, I have the laptop, but I do not know how to data log or anything else. I am not sure how much if any experience Jannetty has doing this, so I am limited on getting the car set up and do not want a screwed up shifting car that I use daily. I would get over the expense, but $900 for the TCM and $200 for credits and probably $ 500 to tune it is also stopping me from just jumping on it. I am confident though if the trans was set up right , I would love it even more.

I ran 11.78@116 w/1.78 60ft DA was 2180 and 76 degrees I think I was off the throttle before the mph trap. Second pass was 11.79@121.31 w/1.75 60ft, DA was 2815 and Temp was 86 degrees.I agree with King on the limits of the A10, its nothing like my A8 was in my 16 Magnuson SS. I also think the converter is a little tighter then the A8. Really had the A8 dialed in on the C7, we dialed in the trans for the last outing in October but there were so many street cars there dragging water to the line we just never could hook the car in 50 degree temps. We had it set up to go 10.80 with the trans dialed in or maybe even a 10.70 since we went almost 130 mph on one of the 2 passes. Last pass couldn't even make a full pass so wasted fuel and time. Glad I didn't break anything but then I sold it in December. Maybe should have kept it. This Lt1 is pretty lazy feeling but just needs some more track tuning and I didn't even log yesterday but maybe I should have.
