Well, raced my truck at the track last night for the first time .I ran a 12.90 at 107. mph .I had on nitto 555r and 61 inch traction bars .My mods are 8lb lower and lfp stage two heads and cams 19 deg timing ,dyno tune,470 rwhp 501tq, and superting fuel mods .My 60 ft was 1.93 . Just wondering if this is a good time,I also have stock eaton,and stock cooling system, and this time was on a hot motor.

 

Is the eaton ported? might want to try lowering the tire presussure also. don't mean to be a ***** but i've seen high 12's from #4 powered L's. you should be running deepper in the12's. my buddy's lightning has a 6 lower, sct ba2400, ngk tr6's, ported eaton @ 17 psi,airraid cai, nitto's 555 r at 18lbs, and traction bars. he put down 495, 590 and ran 11.95.

 

That is a pretty good time for this time of year! Most don't run heads and cams on a stock lower, so it is tough to know how much is left in it.
I would be careful to run adequate octane running 19* timing and the high pulley ratio on the stock Eaton. IAT2 temps are probably screaming hot under load.
One question. Where did you find 61" traction bars? I run the LFP long bars(58"), but am looking at alternatives.

I had a set of cal trac bars before and they suck ,so i custom made a set using the rear axle bracket .I builld 4 link systems for air baged trucks so once i seen a set of 58 inch bars i just built on ther idea and used energy suspention bushings up front and installed hym joints out back ,and paint match the hole kit true blue ,used all stanless hard ware .Last night know one cared about my track time they wanted to buy my bars.Back to my track time I have a stock eaton and a built lower with stock pistons h beam rods .My cam lfp 227 in 231ex at 112 ,They seem to only make power after 3.000 rpm I think i need a stall converter. Back to boost before the 8lb lower i was making 11 psi on a 6 lb lower my motor flow alot more air than it did stock .I guess my next mod should be a stall converter or a ported eaton.I would like to see that lightnig running 11. on a 6lb lower thats seems dam good .

 

Get yourself a PI 2800 stall converter. Of course that means slicks will be needed. Also moniter IAT2 temps to see how hot they get with that 8#er. Adding an ice box may help.
A ported Eaton or MP case will open up the airflow a great deal. It is very cool to see someone try the budget buildup of the bottom end by scrapping the rods only. I will try to keep aware of your results. Post up from time to time as many people have shown interest in doing just rods.
You can make enough power to run 11s with a 6# lower and an unported Eaton. My friend Al Walker ran 11.8s on the stock longblock. He did not have your heads and cams. Wait till you see the difference better weather will make.

Thanks for your help and ideas ,in the future to come i want to port the eaton and dual pass inner cooler and a ice box .This winter i will get a stall converter.

 

i saw your truck run last night. I meant to ask you what kind of work was done to it. I had the red 01.

Nice truck BTW, keep up the good work.

just keep at it, especially when the cooler air is there for you and those numbers will improve!

 

Those Bars sound awesome, got any links to pic's of them ??? Sounds like you really built a kick *** set (Thumbs Up)

As Jim said for this time of yr you def CANT expect your best ET, hence the reason I dont make any passes late spring, or all summer. But it's been cool out lately including Fri Night so personally I would have expected a better ET and more important a better MPH ??? that tells EVERYTHING...
I ran 12.8 on a 100% stock 02 L with a 4lb pulley and open filter, THATS IT,
no bars, no slicks, no nothing, just Stock F-1's with a little less air and a 1.9 60ft

12.8 Run 10/27/02 @57 Degrees

With Heads Cams and an 8lb lower 11's should be very do-able, but you need to get that 60ft way down, you need nice cool air and you can forget about the 555R's unless you put like 12-14 lbs of air in them and heat the ever living schitt out of them (but you'll kill them very quickly like that).

Get a nice set of 28" Slicks on 16" Rims (you can find them used in perfect shape for 500.00 or less) get that 60ft to 1.5's or low 1.6's and BAM you'll take over 1/2 a second off your ET right off the bat BUT you still need more MPH before your capable of running 11's, 112 - 114 MPH to be exact. (may need to check that tune)

But 12's are 12's and thats one fast a$$ Lightning on the street, CONGRATS

 

My problem seems to be in the first 60 ft .I know from talking to people about my setup they all frown a little when i tell them my setup expectially my cams ,Ihave the lfp stage 2 cams .From the start many tuners said they suck to dial in on the low end and start up . I brought my truck to a local dyno in concord, NH . He spent about two hours just trying to get my truck to start good , And come down to a rev without dying .After i put my cams in I loved the way it sound But it felt like i lost 40 hp from the hole.And my track time showed that . My buddy has a chevy thats running 12.5 with a trap speed at 105.0 .On the street i can kill him on role ons.I even raced a sti that runs 12.5 in the quarter ,from a role at 25mph i pull three car links on him .I could use some idea to help out my 60 ft ,add make me not hate my motor so much expecially when i here of you guys runnig 11. with a stock long block and a just a lower .
Thanks for help

Sounds like a 2400 to 2800RPM stall fix to me...

 

2002, when did you go? If was during the week for street night, then never prep the track right...NEVER!!!!!

If it was on a saturday or sunday, they properly prep the track..

It makes a difference...

 

We are usually up there running our Mustang. Don't race the Lightnings much anymore. Got the Mustang in the 9's last wednesday. But ran out of gear at the 1k ft mark!



Don't see the Lightnings up there we used to. There is a sonic blue that's up there alot on street night.

We have the grey trailor that says S & J racing.

Stop by. I'm not tuner but i do have alot of experience and maybe we can see what's up and watch you launch and such. Or if you are in ma, send me a pm, maybe we can meet up and check out a few things. Im guessing you do have the boost bypass mod so your not dumping boost on launch?

Eluzion is right, street nights are very touchy for track prep.

Don't blame the air because it has been REAL good. We've been lucky. Temps up there have been under 60 degrees just about every street night this year.Last wednesday it was hooking good and the air has been real cool so with your mods and 60, 12.80 seems real slow.

Just for reference, I made a couple passes with my truck trying to data log. Left the line real soft........2.2 60'ft time, and still ran 13.0's @ 107 with the same setup as i listed below. Your truck should be alot faster. With a 1.9 60's, that would have been a 12.50-12.60 pass. My best passes were 12.4x's.

I'm guessing you went to Pete at Performance Dyno in Concord.

I was there today. He tuned my buddies truck and helped me do some data logging for Sal for me. He knows his ****. The dyno numbers seem low too. 470 hp but only 500 ftlbs?? Most trucks making close to 500 hp make close to 600 ftlbs......wouldn't most agree.

I ran 12.80's at 1.07 all day on my stock block/heads, 4lb lower 3.55 gears and nittos, even in 70 degreed weather. That's with 1.9x 60's. Would slow down to 12.9's to 13.0's in the heat.

Sounds to me that you have a bad combo of parts. Maybe the stock blower is the week point. Built motor and heads are great but the stock blower is feeding it and at an 8lb lower, i'm sure it's heating things up. Might not be effecient enough for that motor.

Do you have headers and high flow cats? Maybe your exhaust is bottle necking the engine flow. But if you are at 470 with only 500 ftlbs, something is off.

With that torque on Nitto DR's, 1.8's are probably the best you'll see anyway.

Like I said, hit me up, but even with the setup you have, you should be in the 12.0 range anyway.

I would be more worried about motor and tuning then throwing torque convertor and slicks at it. Like I said, that 470 and 500 is screwy.

 

I made a typo on my dyno numbers my truck did 423hp and 480 tq with a 6lb lower .The power curve was really good .Now I have added a 8 lb lower so i AM JUST GUESSING MY NUMBERS NOW . On my exhaust side I am minus two cats and have stock headers ,and a catback exhaust. My iat2 is hovering around 130 to 153 degres. and every thing is working .

 

Did Pete tune the truck after everything was done, or have you changed things since the tune. The torque is low for a 6lb lower. I don't know if it is just the flow issue with the built motor and heads?

I know Pete stays away from doing installs but he does alot of mod motor tunings. He had a whippled cobra up there making some sick number.

Maybe talk to some of the tuners on the board and see what they think but i think it just might be the stock blower.

A KB or whipple with a new tune might make the world of difference.
