Fastest stock internal LT1 on the bottle

I was wondering, whats the fastest time that anyone has reached with the stock internals on a LT1 with nitrous. Any info. appreciated!

Well I'm sure someone is faster, but I ran the times in the sig with heads, cam, dope on a stock bottom-end. Should run 10.80's with a dead hook from the mph I'm pulling. Best previous 60 ft. of 1.55. Ran the time on a 1.61. I still have full interior and functional A/C. Weight reduction would bring even better times. :D

Dirk, RacingLT1 has gone 11.2 with boltson and spray, no cam or heads


I was a tenth off :)

11.25@119 stock heads/cam/tbody and programming here.

I can't remember exact times, but someone in the local Greater Cincinnati F-Body Assoc. is running 11.1x @ 12x in a 3rd gen GTA, using a 275-shot NX wet shot on a completely stock 4-bolt LT1 out of a Corvette.

He also has ladder bars and BFG DRs. His name is Tracey. That's all I know.

There are some boys out here in FLA that went 10.3 at 136 on heads/cam and alot of Nitrous in a 93 Z28. Stock bottom end and everything. The motor lasted like that for about a year before it lifted a ring land.

Damn tell me more!!!!!!!!
136mph I was thinking the bottom end would go somewhere around 126mph!:bow:
Please try to find out how much nitrous. Maybe Shane from Elite Race Cars will know the car.

Fastest in our area that i know of is Kurtis Tamez(moderator).

Bone stock motor never had the intake or valve covers off. ran 11.5 through a bone stock A4 and Converter :D I want to say it ran high 13s low 14s off the bottle;)

Derrick & RacinLT1, How much are each of you spraying? How much timing retard?

Come on! Cut me some slack! Hehe. It was probably a mid-Low 13 second ride at the point when it was going mid 11s. ;)

I imagine I woulda been pretty close to Dirk given a decent Torque Converter. I was dead hookin, but still only went 11.5@120mph, on a 1.61 60'. Just couldn't get it out of the hole fast enough on the stock converter. Like Ellis said, Powertrain was completely stock from the TB to the Out Put shaft of the tranny.

In a Heads/Cam car 10s are fairly common. Dave Brown did it YEARS ago in an M6 Formula.

Hey KTamez how much were you sprying? 200shot:confused:

150hp Nitrous Express Single Nozzle system.

Hooker LTs, Mufflex Y-Pipe, Mufflex 4" Exhaust, SLP CAI, MMC Driveshaft 3.50 Gear'd 9" rear, Race weight ~3600lbs. Weld Wheels w/ Skinnies. Complete Suspension.

About sums up the mods. At that time anyways LOL)

Good luck!

I run a 150 shot,and i believe Derrick does also (even though he is a heads/cam car :D ).
As far as timing,i have my knock sensor limited to 2 degree's and i pull 2 with my MSD digital 6. 99.9% of the time i run VP C10 (104 unleaded) or Sunoco GT unleaded. If i run pump gas (only twice) i pull 4 with the MSD.
Soon as i get my traction issues solved (tried a set of 4.11's and didnt work) im going to move up to a 175 and possibly a 200 shot to see what happens.

Yea I'm running a 150 shot. I'm trapping almost 126 mph and ran a 11.03. What does that tell you? Traction problems. :D Should be in the 10.80's with traction with the current setup. I have a decent cam, but my heads only flow in the high 250's on the intake. That is a far cry from the 280+ that a good stage 2 job flows. So with some more head work, traction, and weight reduction, (I still have complete interior, A/C, and 16" front wheels) I should be in the mid 10's with no problem. All on a stock bottom-end. :eek: :cool:

I ran consistent 119mphs with a 150 shot. went 12.1 this was on nittos with lousy 60's. went to the Et streets and toasted the stock clutch. the car was set up SUPER rich and the weather was hot. Cool air, new tuning and a good clutch...results to come soon:cool:

Spoolin,

They had a custom grind cam, hogged Canfields, and a dual stage setup. Ran pure racegas on the bottle, and had a second 1gallon fuel cell up front for the second stage.

No one really knows what shot it was, they admit to 300+. Just goes to show Nitrous can be half way safe if done right..

buddys 97 . stock heads and intake, cam, headers everybolt on, spray, 11.2 129mph;)

What all this is getting at is...My friend is putting a set of stage 2 stock LT1 heads (2.00/1.60) and a cc306 in his car this weekend, and Im wondering how much he will be able to hit it with.

He previously made 494rwhp with boltons LT4 hotcam and Hooker Longtubes on a custom dual fogger plate. That was with 350rwhp on motor(144whp shot of N20).
THEN http://midnightautowerks.com/ProjectCars/LT1/pics.html
Now he has a TNT F2 kit and gained 112 to the wheels on a 100shot. Hes hoping for 400rwhp on motor with the new heads/cam and he is afraid to spray it with more than the 100 shot jets. Im trying to find him some insurance.
NOW http://xmesh.veriotraining.org/Nick/erik/New%20Folder/

How well would the stock bottom end handle 570-600 to the wheels?

I think anything over 500rwhp is on the ragged edge for a stock bottom end motor. I was making right at 500 on my stock bottom end and it held up fine. I tore the motor apart to put new heads on it and then decided I wanted to build a monster so I tore it all the way down. I think the stock bottom end can hold up to more than 500, but any detonation will grenade the motor. It all depends on the setup and how safe it is. I think the motor will hold 600rwhp if it doesnt see detonation..

Just my 2 cents.

Which precautions do you recomend to eliminate detonation.
I know some type of logging software or a scanmaster is needed to monitor the engine, and also timing should be pulled for a 150 or more shot and higher octane fuel will help. Anything else?

This is from Russ Ehtridge to a mailing list, those that went to the GMHTP BO shootout will know him, changes from the shootout is a stock 'glass hood. Also on his N2O runs he was on the limiter on top of 4th so he got out of the juice. Not sure how much this affects the run but I would think he could pick up a tenth or more. Not sure about the weight on these runs.

Posted from Russ E:
Decided to go run at Commerce last night. The weather must have run
everybody off because there was really only about 20 cars running last
night. Longest I had to wait was 5 minutes to run. Heres a summary of
my runs:

Street tires/on motor Et Streets/Motor
60 ft......2.07 60ft......1.702
330 ft.....5.565 330ft.....5.130
1/8 ET.....8.437 1/8 ET....7.975
1/8 MPH....85.71 1/8 MPH...86.54

1/4 ET.....12.999 1/4 ET....12.511
1/4 MPH....107.66 1/4 MPH...108.44


ET STREETS/SPRAYIN

60 ft.....1.513

1/8 MPH...95.95
1000 ft...9.400
1/4 ET... 11.279
1/4 MPH...119.37

Hooked wicked awesome, never turned the tires over. I also had a
problem with not having enough gear. It was hitting the rev limiter at
6400 about the last 150 or so feet of the track. Guy at the ticket
booth didnt say anything about not having a roll bar!!!

I then drove the hour and fifteen minute dive back home with the A/C on
and stereo crankin, 'cause its a real street car!!!

who is this Jeff or bryan. its Nick, so erik has his heads ans cam done?. ne ways, dumbass he should pull 4* of timming maybe more since its a TNT which is a higher jet, tell him to get a good msd with a retard box on it it

I know about the 4 degrees of timing.We talked to TNT and thats what they recommended. Just trying to figure out what the hell all these guys are doin. Cant you tell by the screen name who it is? ;)

I think the car should have more mph than Russ's being that it went 118.99 traps (first run out) on the stock fuel pump(bucking down the track) :eek: with the 494rw.

It looks like the fastest on the stock bottom end is 136mph...I guess Erik wont be taking that record anytime soon!
:(

Pull alot of timing, run race gas, pray for the best :)

BTW, I never ran my old setup at the track, but I put a car on a guy that went 11.8 at 125..

I was running heads, cam, long tube headers, cold air, 58mmtb, and a 175 shot. I had a Digital 6 pulling 6 degrees of timing on the bottle, and was on pump gas..

I am running stock untouched heads, stock cam and stock intake and a 100 shot with the TNT plate and have gone 11.520 117.13 mph. This was done at a 3920 race weight in a convertible. My 60 ft was 1.59, but im still trying to get it to hook.Im hoping for 11.30's with a 60ft somewhere in the 1.52 range.

Has anyone ever sprayed 150 with the TNT plate on a stock engine?

The car I have been talking about will be running tonight and we will probally hit it with the 150 jets on a TNT F2 kit some time this week. I'll let you know.

Thanx I appreciate it. I would like to try this myself this weekend.

I ran a 12.1 in my SS with a 125 shot!!

Never really ran the same again though...:confused:

~mike

IT BROKE!!!! :cry:

And it was running so well.


I cant believe the timing.. One day after finishing the Cam and Heads the darn thing is knocking BAD. It is diffently the bottom end. It seems that i should have put in a high pressure oil pump. If anyone knows where i can get parts quality cheap let me know. If i can afford it i am going to do crank, rods, and pistons. Tommrow i start pulling the motor back out of the car.

Guess people forgot all 10.59 @ 130 .. stock block, rods, pistons, crank, and heads on a NX wet 150 shot.

I only made one decent good pass on the car last year, at the end of the season. Don't have the slip in front of me, but was an 11.8x @ 110.x, 1.71 60'....spinning through 1st. The trap is low because the wire on my WOT switch broke between my 3-4 shift, somewhere between the 1/8th and 1000ft mark. The car would have trapped around 119MPH that night.

At the time, car was 100% internally stock (valve covers had never been off). 6-speed, 12-bolt, LS1 DS (snapped it the next pass, which is why I never got to run better times on the car). Only weight reduction would be the Ram-Air hood, removed jack/spare and rear seats. Of course, I also have a full stereo system in the car, and my front rims/tires weight 51lbs each. Stock front suspension, about everything aftermarket at the rear, on Centerlines and ET Streets. I'm very sure I could have gotten at least an 11.6 out of the car as it was, by just lowering the tire pressure and running then juice the full 1/4 mile. Still had/has stock throttle body and MAF housing, on an NX 150 shot.

No new times on heads/cam yet, but should have them shortly.
