Drag Racing Results - 107mph in a full bolt on m6? Dont seem right....

So took my 98 m6 TA to the track today and it trapped 107 for all 4 passes. This seems low to me for the mods. 151k on the car. Mods are:

Edlebrock stepped long tubes and ORY Magnaflow catback and cut out
BBK intake with 85MM tb SLP lid with K&N filter and bellow and Ram air
Spec clutch and 390 gear and an ASP underdrive pulley
Taylor 10.5 Wires and NGK plugs
MGW shifter
Free mods
Car is on 17&18: Zo6 rims and fire stone firehawk indy 500 wide ovals. Race weight around 3750ish

Trap speed was between 107.20 and 107.80 for all 4 passes. Times were between 13.3-13.1 with 60' between 2.1 and 2.0. After getting used to the setup (first time with this one at track) I got the 60' down to 1.89 but something didnt work and it didnt record the 1/4 time or mph. I'll post the exact times later whne I have the slip on me.

I remember my old 98 a4 Z going 13.4-13.5 @104-105 years ago bone stock so I think with these mods and an m6 it should be trapping around 110-112? I drove my friends 01SS m6 a few years ago for him and with just an FIPK I got it to go 13.1@108 so whats up? Any ideas? I think it should be closer to 12.7-12.8's around 110-112? Route 66 was the track whatever the da is there. Opinions?

45 views n no opinions huh....weird

I had an 98 with full bolt-ons, stall, gear, and a good tune. Went 12.7 at 109 on a 1.78 60'. Then my 01 SS is running the ET in my sig....heads, intake mani?

yea, i think it sounds low.

have you had it tuned, what was the rwhp and the weight?

Any auto with a stall is always going to run a faster pass then a manual kinda needs a stick car to compare too I think...

No, stock tune. Had a hpp3 sitting around from years ago, tried that it did absolutely nothing.....exactly as expected. Well at least it calibrates my speed for the gear huh haha

With those mods I would highly recommend a tune.

I have seen A4 LS1's with 2.73's, a lid, cat-back, and most importantly TUNE running in the high 12's.

I would take it to a dyno, check the WHP you're putting out. And next, get that thing tuned.

Are you spinning much off the line?

Not really spinning more it bogged some. Got a nice launch once found a sweet spot but the timer messed up and didn't display the time or speed but the 60' was 1.89 where best was 2.0 for the 13.1 pass. As for tune I may Dyno it, but plan to Turbo it soon so no real point in tuning until then IMO.

You are going to turbo a car with over 150,000 miles on it? Good luck.

For what it's worth, I would be adding an LS6 intake to that car also.

my 2000 SS M6 went 12.1 @ 114 mph if i remember right.......with terrible 2.? 60'

it had nittos,410 gears,ls6 intake,underdrive pulley,headers & ory-pipe.

but it had under ten thousand miles at the time.......

Yup...never said with this motor tho.... :)

Had ls6 with ported stock TB....swapped to bbk 85 and 85mm TB....felt better. Also it'll work better with fi.

But at what weight and what h/c? I've had 5 of these cars I know they won't run that on just bolt ones stock weight....and espically with a 10 bolt.....if you were all stock h/c and 10 bolt stock weight well that's a freak!

I did the same thing a few years ago, I swapped my stock LS1 intake out in search of ET and the BBK slowed my car up 3 tenths. I was consistantly in the 12.7-12.8 range and the intake slowed the car up to 13.0-13.1 We adjusted the tune for the intake it never picked up, swapped the LS1 back on and back to the 12s the car went. I experienced the same thing as you though it felt stronger on the street but the track results told the story. So you might want to look into an LS1 for comparison sake.

151K....I would do a leak down test on the compression for a start and go from there.

I went 13.5 @ 105.5 mph in a 2001 SS with SLP FLOW PAC, 1 3/4 kooks headers and GMMG on fresh-ish GS D3's. It's a 01 so it has the LS6 intake I can't remember what the 60' was, but it wasn't great. It was my very first pass on a track. The car is a 6 speed stock clutch at the time and about 40k on the clock. I don't think you're too far off from that. Mods are similar as well.

Reeeaallllyyyyyy.....Very interesting....Were you running the the LS1 or LS6 intake? That is VERY strange if you gained from the LS1....

Not a bad idea actually....I never had a motor with bad conpression before or any of that, wouldnt there be some symptoms or something?

Hmm, ya know I'm wondering it its the rims. I have a couple friends who told me the big 18" rims in the rear and 17's up front because its heavy rotating mass, and not just regular extra weight that it can hurt more then one would think I guess.

Oh also I tried running it with the cut out open and closed, made 0 difference in mph or ET. Some people may find that interesting...

LS6 intake and a tune will help you out IMO. At least look into the intake to go with the future turbo.

But at what weight and what h/c? I've had 5 of these cars I know they won't run that on just bolt ones stock weight....and espically with a 10 bolt.....if you were all stock h/c and 10 bolt stock weight well that's a freak!

yep,stock head & cam with just the spare tire & jack out for weight,stock clutch & 10 bolt with gears & nittos......had a vfn hood on that car with some umi suspension,lca,panhard & t-arm.

i have had 5 of these cars now too....it can be done & i know people that have done better.

good luck!

Ive had the LS6 intake many times on more then one car. Its just not impressive to me, never ever felt a difference over stock LS1 when doing a swap. The BBK 85 with TB is going to out flow the LS6 anyways. I was just looking at dyno numbers comparing the 2. But yeah I'm sure a tune would help but I still thing the trap should be a few mph higher which is why I think something is not right sommewhere...:bang:

Yeah the suspension helps alot too, I'm going to put on a set of lighter rims and see what it does next week. Right now the suspension is completely stock and the car weighs 3770 with me in it so its def a heavy sob. Only thing I have out is spare tire, but im sure the rims, 2 amps and a sub make up that weight huh

i think these guys are right.......dump that heat soaker & get a ls6 intake.

on one of my 98s,it was an a4 tho.....

put a tsp cheapy head cam package & cheapo headers with a magnaflow,pt4000 stahl......car ran ok,but had 273 gears & stock ls1 intake & t-body.

changed the gears to 373 in the stock 10 bolt,livened it up a bit.......
put on a ls6 intake & it got a little better.....
finally put on a ported t-body & BAMN that car came unglued,dynoed 407rwhp & ran a 11.08@121 with a 1.48 60'

one more pass in that car & it would of ran a high 10.9?

then put on a fast 92/92 & lost rwhp on the dyno...........

its all about the combination.....getting it to work together.

My 2000 Z28 M6 went 12.8 at 106 with headers, ory, stock catback, 410s and a lid on some et streets. Turned around and put a LS6 intake and a ported TB and lost the et streets it started trapping 109. All on the stock tune.

jeez 3 mph? Thats impressive, especially for being untuned.

My car with lid/tb/LT's/cb with an M6 has done 12.5@111.8 on nittos. That was with no tune and a 1.99 60'

2001 car so 241's and LS6 intake.

Yeah the 01-02's always seem a little quicker then the 98-00's. Better head casting and different cam must work better with the LS6 intake. Never felt a difference going from LS1 to LS6 intake on any of my 98's but noticed a slight difference on my 00Z. Weird...

Turd... thee end

Nice numbers :thumb: But cant compare stalled H/C setups to stock now...but ur right its all about the combo...but on this car theres no combo its all stock heads and cam. If anything maybe the intake is a little much for the stock cam and junk 98 heads idk...I might be going with an LQ4 for the turbo setup here shortly so then the extra volume of that intake will come in handy. I dont like the idea of a plastic intake for forced induction :drive:

Reeeaallllyyyyyy.....Very interesting....Were you running the the LS1 or LS6 intake? That is VERY strange if you gained from the LS1....


I was using the factory LS1 that came on the 99. Went to the BBK and the car slowed up, put the 99 LS1 back on and it picked back up.

That makes no sense....U sure it wasnt just different weather conditions or something like that? :confused:

The only way that makes sense is if the DA was drastically different or the intake was improperly installed/defective. The ls1 intake blows.

Thats kinda what I was thinking....and every dyno I've seen the BBK 85 has always picked up over an LS6 let alone an LS1...

That makes no sense....U sure it wasnt just different weather conditions or something like that? :confused:

Same weather conditions actually better air one week. I even let the damn thing cool down an hour between runs. That BBK intake I had was a lemon! The one my boy had on his GTO, picked up .2 in the 1/4

Say what you may about it, there are members on here that can testify to it. It was properly installed and tuned. I thought I'd mention it it because your having an issue with your times. Good luck

I'm surprised no one asked the DA. Unless it was asked on the 2nd page.

My BBK actually runs better a little armed up it seems. I ran my best time after driving an hour to get to the track and driving straight to the staging lanes. My slowest times came after letting it sit. Not sure why. Definitely an improvement over the LS1 and the heatsoak stuff is BS. Been argued over a million times. from the sounds of his setup I would say a tune is definitely in order.

definitly get a tune it really woke my car up.i ran 12.97@108 with a 1.969 60 with the ls1 intake and stock tune with nitto street tires work on those 60 ft times and u should hit 12s

Your run that had a 1.89 60' probably would've landed you in the 12's. I'm right there with you mods in signature. My best is a 13.40 at 107.4 without a tune and i have 95k on my car. My 60' was a 2.1. So you figure if you had a 1.89 60' which is 2 tenths better than your other runs thats 4 tenths in the quarter and more than likely going to give you a 1-1.5 mph better trap. Add a tune in there and you can expect to see another 1-2 mph faster trap. So get a tune (which is where i'm at too) and keep doing 1.8x 60' foots and i guarantee you will be trapping 110-111 and running 12.7's. Hopefully same here to, keep me posted. :burn:

*Don't over think it man the 1/4 mile is all about the launch. My 92' Camaro had a vortec 350 in it ran a 13.1 at 105 and was .4 tenths faster in the 1/8 but only .3 tenths faster in the quarter than my untuned ls1 because It has more top end than the vortec setup but wasnt leaving the line as hard.

Had ls6 with ported stock TB....swapped to bbk 85 and 85mm TB....felt better. Also it'll work better with fi.

Actually, it wont work better with Forced Induction. You're only going to keep the incoming air warmer with the BBK. People have pushed 20+psi with the LS6. Its the FAST intake that has problems at higher boost levels.

And I've had the Weiand Aluminum "LS6" intake. I wouldn't run one again if someone gave it to me. Get rid of the BBK and get a tune.

Any updates man? I'm running tonight with some et streets and just got a tune

I was using the factory LS1 that came on the 99. Went to the BBK and the car slowed up, put the 99 LS1 back on and it picked back up.

2mph and a couple tenths over the the ls6 intake with the bbk intake and 85 mm tb my 99 ss i have now has pp intake and 85 tb and both cars had tsp headers and true duals no tune both a4s and they both ran with in a tenth of each other I just wasint happy with the ls6 too much

yea what about them blowing to bits with forced induction Ive seen that happen a few times if it decides to backfire
