Stock LS3 with F-40 transmission. Stock 215/60R 14 tires.

Jack did you try running with those other rims and tires to get better traction? And wow on the trap speed. I know your car really pulls once you can get enough traction. And what gear did you start out in?

H$ll yeah....Good to see some LSx times being added to the list...MPH tells forsure that the cars can run much faster times...With some practiceI see high 11s out of both of them. Congrats to both....
Mark, I tried the tires Joe loaned me and all I could do was spin them all the way down the track. I could not get out of the 15s with them. The tires were 17s with little sidewall and I think that was the problem, thank goodness I brought my good old stock 14s with me. If I do this again I will look into a set of drag radials.

That is what I was wondering about. Someday maybe we will have to line up together. I think I would beat you out of the hole and then be trying to hold you off all the way down the strip. Maybe we should do it sooner than later so I might have a chance even. Once you can get all the Horse Power and Torque to the ground I won't stand a chance.
If so, maybe a bit more gas next time... or were you trying hard not to spin the tires at the start?
Yup.... tires I have suck a huge one. 205 all around tires that came with rims believe theyre w rated too ewww. Planned on going 235's. That and my mysterious surge track night wasn't so bad other days it really to be blunt pisses me off.
I tried launching it and netted a 2.3 spun like crazy. I know its capable lower times but I didn't try any more after I felt the surging not sure if its knock or the maf tables needing more adjustments on the n* tb. It was dyno tuned didn't see any knock issues.
On prowl to get it turbo now with real tires by next year
I had a stupid surge this spring...Check you spark plugs the spin on top cap piece was loose on 3 of my plugs... Went to autolite 104"s problem solved..
Mine where NKG's also...I had never had a problem with NGK's until then.. I was in the process of checking the wires out to see if they had any cracks when I noticed the top of the plug was loose.. So I swapped them out and it went away...
Although I don't do the quarter mile, I do autocross. It's always a fine line at launch between "bogging" it and a smoke show.
Wider rubber in the back should help your car a lot. Looking forward to seeing more of your runs.
My friend claims wider won't help 1/4 times on speed itll decrease more mass.. I don't know why I try to reason... maybe ill hit it one more time with plugs and 235 tires. I'm guessing I could go that far just need to get rim specs. I know it should be low 12s with those traps

See if you can master a 2nd gear start for the 1/4. Worked for me on getter a quicker time (way back when), SBC had a lot of torque, so time was shaved considerable by eliminating the 1-2 shift. Looks by video that you have enough power/torque in second to do it.

Well went a new Personal best again today. Cut an awesome reaction time and a great 60 ft. I wish the timing was turned up for that run but I was testing the race gas to make sure it wouldn't detonate.

Good time and 60'...1.6s is what I used to cut on my old setup all the time with DRs..MPH looks decent for a SC setup..Need to add a 100 shot so u can gain on the top end....bring it down to a low 11...Congrats
I am watching this as you and I are at just about exactly the same ET/MPH.
I noticed that. Same mods except looks like I am Intercooled and have a XP cam. What gears are you running in your 4t65e? I think I'm going to try and spray a 75 shot here next spring hoping to dip into the lower 11's @ 120mph.

I would say the E 85 offsets the intercooler. I have the stock 2.92 ratio - darkhorizon talked me out of lowering the ration in another post a while back. I can manage a fairly consistant 1.67 60' time. do you have lower gears to get that 1.6 60' time?

I have 3.29 gears with a custom built converter.

I was kinda worried about lower gears and converter ganging up and destroying axle parts with good traction. Any breakage so far? Also, I was thinking too of playing with nitrous next year (almost winter in MN). From the research I have done, it seems like 75hp shot on top of our fairly maxed out M-90 setups is about it - so I am not sure if DH was kidding about the 200hp shot or not. I did think that if the basically stock l67 can handle 600 hp turbocharged, why would it not be able to handle a 200 nitrrous shot on top of the 370 hp (estimated) we currently have so long as you retard the timing and keep the AFR in check. I just have not heard of anyone doing more than 75 on the L67 - have you?

As far as breaking axles, I have not had any problems. I've done numerous passes in the 1.7 60ft area and 4 to 5 passes in the 1.6's and numerous passes on the street without any failure yet on axles. Knock on wood. I'd say I've hit the sweet spot for this setup. It's done amazing on the street and I can gauge traction easily. Now the turbo folks have way more power and this is merely a comparison based on what I've done. On the street, I've lost to a couple of FAST cars but I've also beat a handful of 10 sec rides that either don't have traction or just plain can't hook up like they do at the track. From a dig not a lot of cars can hang like our setups can. Turbo cars can do well too, but sometimes when the boost comes on it makes it hard. I think a 75 shot is going to work really well. Keep me posted on your setup, etc. Nice to see someone with similar mods racing!
When I was SC'd (3.4 pulley 1.9 rockers stock springs and everything else) I went 12.5@110. Sprayed a 100 shot same day and went 11.9@120 on 110 race gas. Getrag 5 speed. Can't remember what tires. I only started to spray at the end of 2nd gear. You guys will pick up more than you think.

Did you ever go past the 100 shot? - why or why not? Just trying to gain info for if/when I purchase a nitrous kit to make sure I get the selection of jets I am planning to try - 50hp/75/ 100/ ???

That is the thing that makes these fieros so much fun - we can pull a 1.75 sec 60' time at just about any stoplight. Not many camaros/mustnags/vettes/ or other muscle cars can do that...

100% agree with you. The torque we have at any light is virtually unbeatable from a stop. It's really effortless to get it to hook up especially on my Nitto 555r tires.

Converters are huge trap speed bandits. To really gain in the converter side of things you need to go WAY faster at the line, which is tough to do considering you have peak power at most any RPM on a 3800.

Few FWD guys have played around with big 200+ setups but due to being derps and or FWD holds them back from producing much of anything public. The "shops" that do most of the advertising doesnt do much to sell it as there is not much money in reselling a nitrous kit for $10 profits.

Nitrous is really quite harsh on a motor.. the nitrous turning on and off is a very binary thing which is not easy on anything... but yes the only thing you have to be worried about is breaking something... A piston is going to break from detonation or overheating (nitrous is pretty cold if your afr is right). The rods will only handle so much power vs rpm, but we have proven those in ideal and less than ideal conditions are very healthy still.
I did a little fiddling around with a 50 shot for awhile and I basically couldnt screw it up.... And I never bothered doing any tuning work on it.

not sure if its knock or the maf tables needing more adjustments on the n* tb. It was dyno tuned didn't see any knock issues.
