yes it was lower than expected. i was expecting around 115.
Gm h100mph(14.3),
trifecta k04 105mph(13.9). (i did 13,9 108 ko4 tft DP intake)
zfr trifecta 111.67mph(12.8)


dont forget it very not a aggresive tune but Eric is very happy and confortable.

 

Only managing a 13.9 on tft and those mods. Should've at least been mid to low 13s.

Yeah I ran a 13.2X @ 110 on a 93 tune with only the intake mod and a full 3" exhaust

 

extansa toyo dont help me

Jeff did 12,8 113 with 10% more boost in first gear
he has DR

u need 2,0 2,1 of 60' to pull low 13' with 2-3 3-4 nls
high 12' = NLS 1-2 2-3 3-4

i get a huge deal on pair of BF DR

 

Still low. I trapped 122 on the s256et on pump gas as well. Safe tune. Only 75% of torque allowed in second. And before we had a proper boost controller - we only made 360wtq but made 434whp on that tune. 111 seems off. Even if your car weights 300 - 400 lbs more.

I think my car would top out with 123/124mph traps on pump and maybe trap 127/128 on race gas ***** to the wall.

Uwlizz you have a stage 2 ported head, which works miracles. Wish we could have one for the lnf.

 

Highest I've ever seen a 256et bolt on was on an lsj and he trapped a 116. You must have more than just bolt ons, E, and a turbo trapping that high.

I honestly don't

 

12.938 @ 115 w/ 2.4 60'. Stock turbo, street tires, e85
12.910 @ 122 w/ 2.5 60'. ZZP s256et, street tires, pump gas


quicker par 0.2 sec and faster by 7 mph
this guy invest in right spot for ź. The Rop install his setup within 5 hours no leak and tft tune was as much.

dont forget his gain vs ours
it is not because you have better 60' that you get HIGHER mph
trifecta k04 105mph(13.9)
zfr trifecta 111.67mph(12.8)

he is 1,1 sec quicker and 7 mph faster both were on 91 oct.


to be honest i not very impress by your setup

 

Good Info in this thread....Keep it coming.

 

why did you remove your sign?

 

No wonder why raver trapped so high if that is the truth. His 60fts blow. Major lack of power or tire spin through the 60s and shifting gears way too soon causes high trap speed cause your in another gear longer. I just ran a 12.97@ 113 on a Zfr fully bolted on 93 in 92* weather and 85% humidity. Easily can obtain a low-mid 12 on better conditions on 93 and streets.

By the way, I'd love to see these slips of runs on the 256et, raver.

^ Your kidding right. How would I shift a gear early and pick up more trap speed? I'm on a big snail I make all my power top end lol of course I have to keep it in the right spot.

Yeah my 60 foots blow 1- ) I'm not on slicks and 2) I had a stock trans at the point and wanted it to live for a couple of months. 3) Yeah I start by reving it to 2.5/3k and i'm not in the spool zone of the turbo when I take off. It takes a little bit. **** if i had revved it to 5k and gone with slicks things would have been better. 4) I would probably pick up a mph or two if I was on slicks and wasn't spinning out all through second.

I never professed I was the best drag racer - i dunno if you are trying to insult me.

If we are going to insult, I trapped 115 on the stock turbo with a quicker 60 foot time and cmiller8006 trapped 117 on the stock turbo with a 1.7 60 foot time, so maybe your theories are completely wrong! And 111 and 113 on the zfr isn't something to brag about! Hell there is a video of a cobalt trapping 118 on that bnr turbo, look it up. The spanish guy - forget his user name.


Race gas 480whp i'm guessing and 126mph traps on 1.8 60 foots.

I visit this site sometimes on my cell, and when I post, my signature doesn't show for some reason.

Ah! An old video of my runs...ya i'm not good at launching.


Clearly my car is ******* slow because how on earth would I start catching that car that did a burn out beside me unless I had some serious mother ******* power.

As my tuner SSkev or OntarioKev if you have any questions with my setup or the power it is making.

 

When you have a good launch and perfect shift you reach your et at a good time and slower mph. But if you have **** launches and run your car hard your higher rpms are extremely aggressive and get more of a spike rather than a power band. The power comes in later rather than sooner.

Example: I was stock turbo and simple bolt ons (catless dp, intake, cp, and tune) running 111-112 on shitty 2.5-2.6 60fts running high 13s. When I got my launch down I managed 2.0-2.1 60s and managed low 13s @ 106-107. You 60s dramatically reduce and effect your trap and et.

Another example: A guy at the track Tuesday with a 5.0 twin turbo mustang. When he babied it in first and second but hammered the others, his traps were through the roof ranging 13-14s @ 130-135sh. When he got a good launch and beat on it he was getting low 11s @120s.

So like I said how did cmiller8006 go 11.9 at 117 with a 1.7 60 foot...if your theory is right

 

Simple answer is he made more power on stock turbo. He was putting more power down. That's all that's to it. You are not looking at the whole picture of drag racing and taking a ton of factors into play, its not all about trap speeds.

The video you posted about of the black cobalt running 11.43@126 compared to cmiller running 11.9@117 is completely different. 2 different turbo set ups, 2 time different spool times, 2 different tunes.

All I'm trying to state is, if you cut a decent 60ft compared to some of the runs you say you have, you won't be trapping that high especially if you're on just the mods you say you have. Take it however you want, as insult or not, I'm not gonna continue to go back and forth as you're not seeing everything.

FWIW Startingline with the stock motor S256 LSJ was trapping 127mph last year. I hope to trap around the same with my little 252et when I put it on, which should be possible. Even with no snail I was trapping 119 last year before the cams and 2.6" and on 26" radials. Also, all my runs, no matter what the ET or 60' have been within 1 mph of each other. Just what I've experienced with my car anyways.

For a random comparison we will see what my friends LNF with a 5557 runs this year. 4 lb/min smaller than the S256et and made 476whp at 26lbs.

Also, people act like driving a big turbo setup down the track is a cakewalk like running a stock turbo. It takes some seat time and dialing in.

 

Thank God someone knows what they are talking about here.

 

Hell what do I know. I'm just gonna quit. Next time I'm at the track I'll get a couple complete **** 60fts spin tires and weird shifts to prove my point.

Dont get all bent up because of a good discussion with multiple inputs. First it was mentioned that the s256 kit hadnt gone above 116mph on a non ZZP car, and I just said that is false. However I do know the car you speak of. There are also more cars out there that havent been to the track that really should just so we can have a little larger database for bigger turbo cars times. A few of us TVS guys hit the track, but comparing TVS and turbo numbers are much different. I was running low 12's and trapping 119 with maybe 360whp. This year I plan to run high 11's and trap 120+ with a fair amount less than 400whp.

Also, I said MY experiences at the local track is that my 60' times have had little to no affect on my trap speeds. That is from stock to my current setup and everything in between. Although the more my tires stick at the track the less I have to back off the gas, so Ive never made a run just purposely spinning the crap out of my tires. There are some people that dont know how to drive out there though.

 

Yeah Cuz supercharged lsjs have instant torque available to them and a much different power band than a turbo car...which brings me to my next point....in the k04 you max out power at 360whp say on e85 at 5.5k...after that the acceleration stops. Why in the zfr are you trapping less when you can create almost the same instant torque yet carry 400whp horsepower up top to 7kish. It doesn't make sense that you would trap less than a stock turbo tc. I wasn't trying to insult you wert...but I make all my power up top...it would make no sense that I shifted early and got a redic trap speed.

 

Hahaha. I'm not getting in any way shape or form. I trapped 112-113 cause it was my first time at the track with a good tune. I ran those numbers also in 92* weather and 85% humidity. Only reason why I went is cause it was a cheap night to go and only like 10 ppl were there. I went for ***** and giggles. Car has way more in it but the east coasts climate lately is so humid it blows. As trapping for same as a stock turbo the car has a lot more of a powerband and a lot longer power band.

You ran a 12.9 @ 122 on a 2.5 60ft when I ran a 12.9 @ 113 with a 2.3 60ft. Not saying a whole lot and it doesn't seem like the set up is all worth it especially if you're just going to et a decent time but trap crazy high. You just need to get more seat time in the car. Not saying I don't either but I clearly admitted it especially since its a different set up than what I had.

To me something just isn't making sense if you're saying you're car is trapping crazy high but your et is the only same as mine. If you nail a decent 60 ft you'll see the difference et and trap wise.

Just curious. What are you guys picking up for mph in the back half? I was picking up 30mph in the back 1/8th last year.

 

LOL yeah I was 88 mph in the 1/8th lol...so 34mph! ha

The answer is in the tires, the tune, and the boost controller.

The fact of the matter is with any huge power setup you need slicks it's hard to really get a good et with fwd manual trans on street tires.

 

Ah I also just remembered about something else that effects your trap speeds. I normally rev out 3rd and don't shift into 4th. If you shift into 4th your into a whole new power band. When I shifted into 4th I trapped 116 and a 117 but my times were slower.

At the 1/8th mile im at 90mph flat. Reving out 3rd I picked up 22-23 and got me my 112-113. Shifting into 4th would pick me up more like 26-27, but added up to a slower time by .2-.4 seconds.

That all depends on the turbo and where it makes power. For me being SC, I make peak power at 7600, so probably a tad lower than that when I made my runs on stock cams, but I stayed in 3rd across the beams every time because thats when the car was pulling the hardest. Its funny having people ask you if you seriously really only shifted twice after watching you trap 119mph
