11 Second Club - 400RWHP enough? UPDATE -5/29

I have been in the 10's before with 375RWHP but I know these cars are different and heavier. This car I just got made 406 or something. I'm wondering if you guys in the 11's have dyno'd 400 or less.

The car is 98 Z
6 speed
4.10's
26 inch drag radials
400RWHP.

That shouldn't be a problem.

I know cars with 380hp running 11.8s so you should be able to cruise easy into the 11's

Granny shifting will get you there. If the track hooks... Haha

400rwhp should give you plenty of hp to run the mph needed to run in the 11s, but the 11 second slip will come with how the rest of the car is set up. If it doesn't hook it obviously isn't going to happen. Also what does the dyno curve look like? Is it real "peaky" or have lots of area under the curve, and at what rpm does max hp and torque happen? You also have to have confidence that the dyno isn't too overly "friendly" when it comes to the numbers it spits out.

FWIW my old Formula only made 375 rwhp on a calibrated Mustang Dyno and weighed 3600ish pounds and ran the numbers in my sig.

Definitly possible. There are plenty of stock internal cars in the 11s and you won't make 400rwhp stock internal.

Thanks for the replies guys. I didn't see the actual dyno. I know it made 406 and maybe 375 TQ. The car has the following:

Ls6 intake, pacecetter Lt's, ORY and SLP LM exhaust. It has a T-rex cam and bigger MAss air and injectors and a Racetronix pump. Fast toys ram air kit and lid and has 4.10's and 6 speed. The car doesn't have dog crap for power under 3500 RPM's but rolls out after that.

I was told it has been low 12's at 116 or 118 with bad 60ft. I'm gonna get to the track not this wednesday but next wednesday. My goal is to roll into the 60ft easy and hope there's enough motor here to get a 11.99 pass. I have broken way to many 10 bolts to go nuts with it. If I like the car and it performs well I will probably spring for a 12 bolt, a NOS kit and a set of Patriot heads.... in that order.

This. Depends on how you can launch the car.

Yikes will be a tad tough not launching hard due to the rear/

My buddy's ws5 went 11.8 with 407whp he launched hard at 5k with stock rear end, ms3 cam, lt's, and a tune, 4.56's in the rear

11.91 with 340 rwhp

11.94 with less than 320 HP completely stock engine with just headers never had the valve covers off at 3,665 lbs. it was in good DA!

Shouldn't be hard with 400hp. A friend of mine runs 12.0-11.90 and has a stock internal 01 with 3.73's, Yank SS3600, LT's, and has no weight reduction except Draglites.

My mods and numbers in Sig. and that was before it got tuned. Just put down 409/393 once it got tuned.

Cts you can't have 4.56 gears in a stock rearend

i went 11.50s with 360 rwhp in a gto

might be harder than you think with the 6spd/10bolt unless you don't care about breaking it.

Cts you can't have 4.56 gears in a stock rearend

yes you can. my friend had them in his z28 with the zexel torsen.

im 11.5 s with a bolt on gto (360 rwhp)

400rwhp is capable of bottom 11s in a 3400#ish car, 10s in awesome DA.

My old 02 Camaro SS had 320rwhp and ran 11.80 w/ no weight reduction !!!!!

I ran 11.97 with 325hp.

How are y'all getting into the low 11s with sub 400hp and full weight?!? I cut mid 1.6s

I was cutting 1.50-1.52 short times barely spinning running consistent 7.3@94mph. That was at 370rwhp 2200ish DA.
I added x pipe with 1chambers which dropped some weight, chrs1313 RAM air which added no dyno HP, better tune. hopefully that combined with a dead hook 1.48 and good air will net me some 7.0x @ 96mph.. which would be bottom 11s, scraping 10.xx.

Most setups have to be in the 1.4x 60' to hit bottom 11s/high 10s. Although, all Dynos are different.

I have raced VERY good da here in south Texas. Are you using a brake to get those 60s? Or is your suspension just dialed in?

I still need front shocks and a drag bar, I was spinning before so it obviously could have been better. That with a better DA, there Is a decent amount left In it.
Im just on foot brake. Absolutely nothing special about my setup, DA, raceweight, etc. 226/228 .588 114 cam hand ported milled 317s ls6 intake full exhaust lid 373s... raceweight 3450 with oeo stars and 1/8 tank gas.

Good sixty in my setup=ptc 4000 converter.

Buddy with bone stock suspension, 4000 ptc full exhaust and lid, ls1 intake 273s full weight 98 trans am..1.60-1.65 short times 2400 DA.

what kind of str do you have on that converter? i should be hitting the track with my new setup in a few weeks. Im looking for mid 11s on motor and high 10s on the hose. I still have stock torque arm and stock front suspension.

I have a very similar setup (still stock injectors and maf) and i've gone 12.2 @ 114 on 1.9 60' in 2200ft DA. I think you're good for 11's

Ptc doesn't really give their converters an STR. I would put it in the ballpark of a 2.4-2.5. It hits very hard.

I still have stock torque arm and stock front suspension.i foresee a bent torque arm in your future.

i bent the one on my car with boltons.. :( i guess a hard hook and 3700lbs will do that hahaha. funny thing is the car went 1.60 still spinning.

11s with 400whp and a t56/10 bolt will be tricky. i know it can be done, but it is def not the norm. any updates?

im leaning more towards the stock 4L60e blowing before i bend the torque arm. only mods are a huge trans cooler and the circle d stall

A local guy (he's on here) almost got into the 11s with much less than that. He had some gears, suspension, big converter, a 12 bolt and some DRs and ran like 12.0x I think. Only performance mod was a magnaflow muffler.

With a 6 speed, it's all about getting off the line well and without breaking the 10 bolt. You have more than enough power, but it will come down to driver skill and traction.

Its def tricky to say the least!!! I have 423 rwhp t56 and a stock 10 bolt its not fun knowing you can blow the rear end with no effort! I am going to just hammer it next time and see if i can pull a high 11!!! So far 12.5 1.99 60 ft so with a better 60 it will be close these damn auto cars have it easy!!!!!!!!!

If you feather it out of the hole you will most likely run in the 12.05 to 12.20 range unless you have a decent sixty foot.

I raced a 6speed camaro with 500 hp and had a stock rearend twice. It ran a 12.01 and 12.20 based on my memory. It can be done but you will have to a decent sixty foot.

The big thing is the weight, I have 487 rwhp and 500 rwtq and the best it run was a 12.70 and that was on a good night

11.50s @ 120 400hp

Update 5/29

I should have asked if I can get into the 12's , lol

I never accounted for my lack of 6 speed experience. I have been in the 10's on Automatics.

1st run I couldn't hear the motor over the pro stock car in lane 2. I was trying real hard not to break anything first run.

13.20 @ 114 with 2.5 60ft. I was in and out of it and shifting like grandmom


2nd run was a big mess. Not worth posting times. It was very amateur driving to say the least


3rd run was a decent 1.8 60ft and 7.90 to the 1/8. The car was moving. I went to shift into 4th and the clutch issue i'm having wouldn't allow the car to go into gear. IT just wasn't there so I had to abort.
It ended up with a 12.60 @ 93.


I'm not to dissapointed. I know 7.90 1/8 may be an 11 seconed run so i'll try back again next week.

Sorry to hear about the bad luck! My guess the 7.90 run would have been somewhere around 12.30's! What was the MPH in the 1/8 and the ET at the 1,000 foot mark?

Hope you get everything fixed so you can have fun on the next outing!!


N2

At least you know with a half ass sixty it will run a decent et.

i think that 7.90 run could've been an 11.99...depending on how well you got 4th. my bolt-on automagic car would run 12.30s with a low 7.9 1/8 with only 108 mph. i'd like to think your car would flat run away on the top half.

practice practice practice. 6 speeds are def trickier to drive. i went from a stalled auto to an m6 and with more mph i'm still over a second behind the auto car haha.

After thinking it over for a while I also realized something else that would have made a big difference. I know the car pulls to 7k no problem so thats where I was shifting. Problem is that the rev limiter is at like 7050. So I kept bumping into it which was slowing the shifts way down. I'm gonna aim for a shift point of 6800 so it will all go down before the rev limiter. I think that will help get the car down the track.

I'm gonna aim for a shift point of 6800 so it will all go down before the rev limiter. I think that will help get the car down the track.get a shiftlight, place it somewhere in the cabin that will not blind you at night. i have not installed one in my car -yet, but a good friend of mine had one in his car that i drove a few times. makes a WORLD of difference in an m6 car. there is so much going on, watching the tach on a 600hp car in an effort to nail shifts is a real pita. we set his shiftlight and then logged the car to where he actually shifted, then simply set the light to make him shift at the right time. there is a delay...no matter how fast you are, find that delay and use a shiftlight to your advantage, it will help a ton.

I'm gonna try on sat to hit 11's. I ran 12.60's @ 116 out last time with 2.30 60ft. I'm alot more comfortable with the car so we'll see. The weather is supposed to be less humid. 6speed car with 3.73 10 bolt and nitto 555r's

Really work on that 60' - with 555r's I found my car's sweet spot was at 4k RPM's - less and it'd bog, more and it'd spin; find yours and you can cut that 60' by a lot - should be enough to put you in the high 11's (1.9 60' with that same run = 11.8-11.9)
