Hangwire's KB 2V, Tune/gear/exhaust LS1
 

Not sure if you guys remember back when I ran Hangwire. He basically has a KB 2.1 automatic GT with a few mods on stock gearing. At the time I had a lid, tune, and cat-back. This is how a 45-50 roll turned out on the street... http://www.youtube.com/watch?v=U4ErA...5gg&playnext=3

and on the track... I was running 12.5-12.7 at 108-110 back then. His Stang ran a best of 12.9 at 112 that day, first time ever at the track, so not too shabby imo... http://www.youtube.com/watch?v=e0oUQ...3&feature=plcp

Now to the bench racing part. Since then I have done longtubes with an off-road Y-pipe,as well as 3.73 gears and the free ram air mod. I now run 12.2-12.3 and trap 113-114 depending on if I'm hot lapping or not. What would the outcome be now on the track and from a roll in you guy's opinion? He texted me last night saying he thinks I could stay within 2 cars of him at this point. I have my opinions on this, but want to hear ya'lls first. As long as the weather holds, we'll be hitting the track Sunday. Might even be able to talk him into a roll race on the way back (he got a nasty ticket recently so understandably it might not happen)....

I'd bet on you either race.

Sadly I would say you're going to get this one stone. I would imagine the kb car having more traction issues than you, and a stock gear/ stall automatic car I don't see trapping over 114.

Anyone else care to weigh in? We should be hitting the track in Fayetteville tomorrow. I'm at the coast and its been cloudy here for the past two days, but Hangwire says the sun broke through yesterday inland, so its looking good so far!

I think you'll def pull him from everywhere y'all decide to run from.at the strip it'll be ugly and on the street id say you pull him by 1-2 cars. If y'all are able to hit tge track good lunck!!

Yeah my text was about the roll race. Strip will be all him. Roll race will be interesting the gears are going to kill me. Theres a small chance it could get really ugly though because I have an air leak under my blower and its running really lean under vacuum. The computer is dumping 25% fuel at idle and barellllly holds 14.7 A/F. Under boost it HAS been running fine but the leak continues to get worse and i'm wondering if boost could be escaping at this point.

One thing to note is that on that drag strip vid I had 275 Nitto NT555s crammed onto an 8 inch rim and they were crowning hardcore. Not even all of the tread was making contact. I bought 10.5" rims and NT05 315s so the extra tread and correct shape on the sidewalls should help me a little bit. I've gotta learn to prevent any spinning at all bc as soon as that happens the run is over and i'll probly run 13.0s n ****.

Doesn't matter to me either way, its still fun and until I drop cash on the suspension i'm not gonna have real great expectations. I plan to throw slicks onto my 8 inch rims and start swapping those on for runs down to the strip. That should help......up until my differential blows.

The gears are helping me a fair amount, mainly from a dig, but my top end picked up 4 mph since doing headers and the ram air mod.

I think your ET will be much better tomorrow vs last time we went. Supposed to be pretty cool tomorrow. Plus you have a much better idea about what to expect. As for that rear, that sucker isn't gping to let go, trust me. Swap your 8.8 for my pos 7.65 and then you've got something to worry about, lol!

I'm gonna lose about 2-4 tenths once I get heat soaked too. I gotta keep the motor off in the staging lanes as much as possible. The KB gets up to 180 degrees when idling but stays nice and cool as long as the car stays moving. If I kept driving after strip pulls the temps would never even raise a bit. But running it hard then just idling gets her hot.

Ahhh your on a nt05!!! That def makes things better for the track. Run 20psi in the tires and do a good burn out then at the line foot break the car as much as you can without it spinning and if your not loosing boost from the intake leak then I see 12.5-12.6@113


Btw while your at the track buy a bag of ice to set on the blower to help the heat soak.... hell it help my n/a car out about 2 tenths (back when I first bought it)

Just got back from the track. Ran a tad slower today for some reason. A bunch of 12.5s and 12.4s, all at 112 mph. 1/8th stayed at 8 flat and 88 mph all day. Hangwire was running slower today as well. 13.5-13.6s at 108ish.

Got to run one of my track buddies in his 03 Cobra, full exhaust, 2.8 pulley, etc. he ran 12.2 at 116 to my 12.4 at 112. We were only .02 hundredths apart at the 1/8th, but 2 tenths apart by the 1/4. Felt damn good to stay within 1.5 cars of him though. Just sucks it was the only run I didn't vid from in the car! He has an SLP loudmouth 1, so you can imagine the noise that thing was making. Traffic was too heavy on the way home for Hangwire and me to get that roll race in. I was pinging pretty bad due to sorry gas I got at the beach and Hangwire is having some leaning out issues, an air leak possibly, so neither of us was running tip-top.

DA was 1500'.

hangwire needs gears desperatly if he wants to hang with you at all man. the cobra trap seems low as well, my buddy with an intake, tune, 2.8 and midpipe/catback trapped 118. might be the da and temp as well tho, or possibly he wasn't letting it cool down long enough. never the less good times, and i'm still faster et wise :P

Everyone was down on trap speed. Last time I saw that Cobra run, he was at 11.8 and 118 mph.

Hangwire is talking about doing 3.73s. He's got to get that leaning issue fixed too. He thinks he may have a leak under his blower, possibly.

yeah a leak under the blower will cause a vac leak and lean idle along with some power down under boost. hopefully that's nothing more than gaskets.

Hopefully that's all it is. I think that car has some strong traps hiding in it. A lot of stock parts still on that car, throttle body, etc...

didn't it make high 300's at the wheels? that thru an auto is a great number. just needs the rest of the work done, minor suspension, gears, and a mild stall and that thing would likely drop a second of et.

High 380s I believe. What's up with that 108 trap though? Last time out, he ran 12.9 at 112 and the next pass was a low 13 at 110. I'm just wondering how much his stock TB is hurting him regardless of the leaning out issue.

it might hurt him some but if he's making 380 to the wheels thru an auto i wouldnt want to push the stock longblock much more. i'd imagine if he has a vacuum leak it's also blowing boost out causing some reduction in trap.

That's what he said too. Probably a smart move.


Gotta be something like that. 380+ RWHP is good for 115++ at the very least.

Can't he use a bottle of soap water to see if it's leaking?

he could just spray some brake clean around the intake and under the blower at idle and if the idle changes somewhere he sprays then that's where it's leaking. easiest way to check imo.

and yeah stone i'd expect a 115/116 trap out of that car he's gonna need some gear for it tho.

That's a good idea, hopefully he'll read this and give it a try.

Yeah i'm not sure what the deal is with my air leak issues. I have personally gone through all the hoses/fittings myself checking for leaks. I have had multiple shops check for leaks. Nobody has found anything. The symptoms are as follows: Computer dumps all fuel it can @ idle, once I get to driving it starts pulling the fuel back but still adds some. Once my car is up to temp and I shut it off it will run LEAN as hell once I start it back up(open loop). It literally runs like 18 A/F and you can hear the exhaust stumbling like hell, it sounds just like a mild cam. Get this....as soon as I put it in drive and drive around the block and get it on closed loop it will idle fine. 14.5-15.5 A/F and no stumbling. Air has gotta be coming in somewhere. I get lean codes on the drivers side every few months and thats it. Spraying water/soap mixture below the blower around the intake is pretty much impossible - there is no room to get up under there with the intercooler and all.

I have replaced: PCV Valve, IAC Valve, MAF, Driver's side o2 sensor. Exhaust checked out ok with no leaks.

I re-used the intake manifold gaskets that came with my KB kit when I bought it used. According to the seller they had ~2K miles on them. Seller was reliable and from this site so I do believe that. I think it was a bad idea though and I'll bet that gasket is leaking.

Anywayyyys yes I ran slower but I still think I improved. Stone has put on LTs, SLP lid modification and 3.73s since we last ran together and I think he ran almost the same times E/T. So it was just a lil slower day.

First time we went was in October of last year. I ran as follows...

1st Run
Reaction: 1.4
60 FT: 2.30
1/4TH: 12.92
MPH: 112.44

2nd Run
Reaction: 1.11
60 FT: 2.24
1/4th: 13.01
MPH: 110.73

Today I ran....

1st Run
Reaction: 1.30
60 FT: 2.24
1/4th: 13.46
MPH: 109.78

2nd Run
Reaction: 0.97
60 FT: 2.21
1/4th: 13.64(OUCH)
MPH: 108.23

3rd Run
Reaction: 0.73
60 FT: 2.20
1/4th: 13.32
MPH: 109.22

I improved on all three runs today so i'm really not upset at all. I'm getting the hang of it. On that last run I pretty much released brakes fully on the second yellow light and just punched gas and it felt much much better off the line. On all my other runs I was starting as I released the brakes and I think with all this torque thats not really helping me. I need to break 2.2 60 FTs and figure out if this air leak is hurting me or not.

I attached my dyno sheet. The only thing that I have done since then is MAC O/R H pipe.

Edit: 3.73s and/or Megabite JR LCAs are coming soon. Also considering FLSFCs but want to prevent adding more weight for now.

If you do have a leak it is hurting.

Last time me and Hangwire were out there, I was running high 12s (12.7-12.9) at 108-109. Next time with really good air I dropped it down to 12.5 to 12.6 at 110-111. Then after the LTs, gear, and lid mod it ran 12.2-12.3 at 114 and 113. Yesterday kind of sucked for everyone. Seems like all the cars I've seen out there before were down 2 mph. A brand new SRT Chally with pretty good driver mod only trapped 108.

Just throwing it out there, have you checked the injector o-rings?
