Competition Manual beats an auto

[jaybigboy34]

How much more power does it take for a manual to beat an auto down the drag strip? If the trucks are evenly matched, will a manual always get beat?

 

[Turbo Thom]

I don't think HP has anything to do with it. It come down to clutch versus no clutch. You'll never see a 10 sec pass with a 4500 or a 5600. It won't happen.

From a guy that has a 6er ... ..... its a real pain in the butt to crank and yank that thing down the 1/4. I am sure that in time I could get better at it but its really hard to get off the line and not roast the tires... and even when I come out soft I break loose when the boost hits hard. I want to try slicks but I cant find anything of any size in a 17-18" wheel.

 

[TJSHOTROD]

It takes alot. I thought I would over compesnate with H. P. but I think you need like 150 to 200 hp more than the auto. Plus when you make that h. p. the clutch you need to hold it really sucks for racing.

Depends on what time range your talking.

I have dynoed the same as some autos with nearly identical weight and we do the same e. t. and mph.

I think as I get into the 13s the gap will start to increase, but 14s or slower and some manuals are faster.

My brother (01HO) used to have an 01 QC LB 4x4 6 spd. that made over 500rwhp and i think his best was 13. 3 at like 103mph, at the same time I had a 98 24v auto. QC LB 4x4 that made dead on 500 rwhp and my best E. T. was 12. 93 @ 102 that may give you a little idea

i raced a friend who has a 6sp with 485 hp and i was at 375 with an auto. given i do race often and i cut a mutch better light (. 009 vs. . 675) i got him by a truck length. it depends on the shifting i guess

Preston, gimme a couple of years. I have alot of duct tape to put on my truck to do 10's.

 

[Turbo Thom]

The original question was how much more power does it take for a straight shift to beat an auto. I thought JB34 wanted to know on equal terms. Sure a 500 HP stick should beat a 300HP auto. Thats common sense. I still believe a stick will never stay with an auto on equal terms. The 4500 or 5600 cannot be shifted fast enough for a competitive time on the track. That is just fact.

Thom, really don't have an answer to your question. Guess if you have a "friend" with an auto race him, upgrade, then keep doing it till ya win... ... lol.

Really though, if I ever replace my 6er with anything it will be a custom Lenco and then a line lock, and why you ask and not an auto, because I can. Been around drag racing to long, never seen any pro stockers use an auto. BTW "Fat Kid" you and I side by side at the Creek... ... ... ... . lol. One race boxes off, then on, then with your new toy. I may get 2 out of 3..... lol.

See ya soon.

Simple fact is you lose more boost between shifts with a stick truck.

 

[TurboTweaker]

Spicyjam,

WHAT BOX? and its not fair you have 200hp injectors to my lil 80 hp. but any time you wanna run at the creek let me know. i'll even bet you dinner to win.

Cooter!!!!!!!!!!!!! Glad to see you are the TDR. Got a question for ya, something I can't remember, and it may sound dumb. But do you have air in your truck?, you had a ton of room around your turbo and I was trying to remember why. Sorry for asking such a stupid question, but something was missing over there. BTW did you end up having to buy a new set of rear tires?..... lol.

And Fat Kid, even if I did bet you and you could win you would let me win to so I would buy you dinner. It should be loser buys... ... ... ... ..... lol. Ahhhh and Cooter, a Lenco would have no lag... ... ... ..... lol. Only need the clutch to idle in gear and get into reverse, the rest is like smacking the ole girl in the rear to get her going faster.

I only lose 5-7 lbs on my shifts??

I can shift mine fast enough to bark the tires in 1-5, haven't tried 6th (WAY illegal speeds). I am NOT powershifting either

 

[glhs]

Turbo Thom; 4500 or 5600 are too slow. Try a Getrag.

I had an Audi TT 225. with that car, it was kinda goofy, depending on h ow fast I would shift, the ECU would cut boost. prolly 25% of the time I would have to regain boost between shifts. But when it did keep boost, I could hear 4 perlli 6000's squeel a little (1st-2nd gear) and shove the passengers head into the head rest.



As for my truck, I'm able to chirp the tires between every gear except grabbing 6th. Granted it's not easy on things, and I think I killed my throw out barring over this. I don't think I loose boost. in fact with the butt dyno, it feels as strong as a pull the second I shift into and out of every gear, errr I don't feel turbo lag at all.



I think the problem with most of your manual drivers is that you can't shift fast enuough to compete with an auto. And I'm not dissing you guys. But I have ran into many people that are "power shifting" but seem to me like what I I would consider just a basic fast shift to make a sudden move in t raffic.



I don't think the average automatic trans has much more then a TOTAL after 5 gears have been changed of . 200 of a second advanage . maybe even less. Now add in the slushyness of a torque converter, and you gain . 300 on the manaul or more. Basicly, the manual should always win given equal HP, so long as you work that manaul.



Buddy of mine put it best "Shifting your truck is like rowing a boat" .



BTW, I ran a 16. 5 with 100% stock truck with a 4x4 launch, tail gate off, low fuel light on, prolly at about 7100 pounds.

way illegal speeds? and your running 4. 10's so that's 65-70mph as you grab 6th? heh. I cruise at 80mph on a daily basis Back in Michigan, or even L. A, t he speed of traffic can get damn near 100mph



I'm getting taller tires to get the top speed of my truck as close to 120mph as I can with out loose to much handling.
