My 11.1 @129mph!

[kp116]

Kenny's 11.1 @ 129 on Flickr - Photo Sharing!

We were all extremely surprised with the results. Car was on a very safe tune on a single wally 255! Car is on e85 (e70) on a hx40 pro with the bolt-on .55 a/r bep housing. Stock intake manifold and throttle body. Race weight was somewhere around 3150. I still have a lot more room left. This was on yokohama s-drives for tires with a 1.77 60 foot. My trans is very notchy 2-3 so that probably hurt the et a little bit. Car was driven to and from the track which is about an hour and fifteen away. The smoke you see at the end was a little blow by through the dipstick but that problem is solved now. I can't wait for another fuel pump and maybe some small shit and see if I can get into the 10's!

very nice! tens are in reach!

 

[Mr Peepers]

Congrats again Kenny!!!

Haha who knew it would already be at this point, with a good bit left to go

 

[FenixTX717]

you're gunna make it there kenny and I will be there to watch it again!!!!

Very nice times and clean 1g!
Any logs you can post? How much boost and timing?

 

[Mr Peepers]

If you don't mind, Kenny.

AFR was sitting around high 10 to flat 11:1, leaning out a little up top because of the single fuel pump

Boost was 30-31 psi

Timing I want to say was 16 or so degrees at 7k

No good logs and not much to see in them, MAF isn't dialed in yet at higher hz, just going by the WBo2 and aimed AFR, which is still difficult with a fuel system that's not quite up to par.


2nd fuel pump, more time on the tune/MAP sensor for MAF, a slightly higher stutterbox and fix the negative camber in the back and it'll be all set

 

[toofast82]

Thanks for the info, pretty much what I expected to hear as far as numbers.

E85 huh? thats what my friends 91 talon tsi has, its good s*** aint it?

Nice HD quality video, and a good clean looking pass.

Fixing the rear suspension will help a lot. On my 10 second Laser I just added 1/2" to my rear upper control arms as well as installed poly trailing arm bushings and welded the toe adjusters solid. Static rear camber is only -0.5 degrees now (-2.5 to -3 before), and the car looks like a FWD now from the back.

Second gear roll ons where the car would go all over the road before now go perfectly straight with no drama. It's almost boring to drive now I've run 1.66 on 205/55/16 BFG VR4s, and 1.63 on 225/45/17 HTR-Z's so I'm pretty sure your S-drives will take you well into the 1.6x range. Good luck on a 10 second pass!

now thats a sleeper.... great job

 

[JWoodley]

Congrats! Hopefully someone can post this in the results thread. 10s are definitely doable. Can you go into a little more depth on your setup? Keep up the good work!

 

[kp116]

Thanks everyone for the comments. The car is a built 2.0 liter with eagle rods and ross pistions 8.5:1 CR, BC 272's with BC springs and retainers. ACT 2600 6 puck, trans is just a stock rebuild with a welded center dif. Like I said before trans is very notchy 2-3... so a trans in the near future would be nice. For fuel just a single walbro 255 and FIC 1750's. Ecmlink with a 3" GM MAF. It still has a lot more room to go. Once ecmlink release their speed density system I am thinking about going to that and not have to mesh around with a MAF... In the near future a fuel pump is a must. SMIM, possibly a tranny and I would like to degree the BC 272's. Fixing my negative camber issue would help out a lot off the line. I will keep everyone posted on my quest for 10's!

Downhill track FTW



Nice run, and clean Talon.

Punch it at the last amber light and that could have been a 10sec pass! Yes, a little higher studder and better adjustment for squat and you're consistant in the 10s with enough fuel and more timing. 16 degrees for an ethanol blend is very, very conservative. Was that because the fuel was falling off up top?

ET to horsepower calculator.

I'll put this in the results thread.

Fuel wasn't really dieing off but when we first were tuning it it was set at 34psi which was a bit too much up top. The injectors are actually trying to compensate for the single walbro 255 so I have actually exceeded its limits already.... I wasn't worried about the lights, thats only good to get your reaction time down. The clock doesn't start until you cross the beam.

 

[dnhieu]

i have a VERY similar setup but on meth + 93. i need to switch to gm maft and see what i can do! damn 2g maft doesnt allow me to run much more then 24psi.

good runs man! and very clean ride...

 

[95GSXCO]

Makes me mad I sold my BEP housing! Oh well still dont know if I wanna run the T3 or stick with the Mits?

I would assume you have your WG off the O2 housing correct? Which housing are you using?

Yep its a 38mm tial wastegate. The 02 housing I am not sure I bought it with it on it but it looks to be just a home made one... (shitty welds...)

Yep sounds just like what mine was. I had the 2g mas and I was limited to 25psi and only revving out to 7k. I also was running pump 93 and meth for awhile then went to e85 and meth was still on, meth is now off and just e85 . I ran a 12.1 @121mph with a 2g mas e85 and meth. It was opening day at great lakes dragway so I could not break into the 11's the track just sucked.

I did not know that. I've always been told to start at the amber, but assumed it was because they started timing at the green. That advice must have been for beating the guy next to you.

The 2g maf can see about 50lb/min in decent ambient conditions (common altitude and not too high IAT). If you remove the honey combs you are supposed to becapable of seeing about 10% more after recalibrating it, according to the ecmlink base maf transfer function for the hacked 2g maf. You guys are running at what altitude? Thinner air would make lower mass flow for the same volume flow, and the meter technically is limited in how much volume flow it meters (hertz count).

that advice is definately for helping you beat the guy next to you. You could sit at that line for as long as you want. Hence why when you see some drag cars sit there for a second or 2 after the lights change to green....you just go when you want to

man thats fast car

good job!

Our altitude I want to say maybe 800-900ft? I am not quite sure about that. On the hx40 I was on 27-28psi on pump and meth and I could only rev it to about 5700rpm because anything more would out flow the 2g maf.

I have been told it start at the last amber light because the time it takes to actually start moving ect... your reaction time will be usually good. The tree is only good to get your reaction time down and the amber light at the end of the track indicates who crossed the line first not necessarily who was quicker e/t.

good job!

Thanks man. Your car should be in the 11's with a 118 trap! Thats pretty damn good.

just out of curiosity how did you know when you were out running the 2g maf, Im in the same boat as you on the holset, im seeing 53lbs/min by redline and a max hertz 3080hz and i have no sign of maxing it out. thats at 70* IAT's and 900ft ^sealevel and 26* PSI on a 7.8:1 block.
