Stock motor times.

[dordtrecht5]

Built trans, lift pump, Danville 68 mm turbo with billet wheel, head studs, fuel rail plug, Lbz mouth piece with 5" intake, straight centerlink, tie rod sleeves, Ppe manifolds an up pipes. Dsp5 from ATPtrucks. Runnin nitto 420's 305/55/20 from what I've read and everything I should be mid 12's. I hold rail pressure so idk what it is. I'm gonna log it tomorrow agian to see what it does

IMO should be in low 12s. Be sure you are not in a non-dsp tune, or in other words your base tune. If you go through the switch EFI should read out which tune your in. Ask be how I know about seeing a 14 sec run after spending a bunch of money on performance. I was stuck in tow tune. Not bad for a tow tune though with a stock turbo.

Lol I know Which tune is which. And ya I know I should be somewhere around there, but Idk why I'm not getting there. The only thing I can think of is my lift still being on the truck (even know I put 3" drop shackles on the back and pulled the torsion bolts out) cuz I hop bad when I launch around 15 psi but I don't see how that could slow me down THAT much. I'm gonna try and strap the front end down next time to see what that does also.

 

[RedHotGMC]

what are your 60' times?

 

[Chevy1925]

You should easily be in the twelves. I hit a 13.04 with built trans, lift pump, twins, a little weight reduction, 37s and my lift. Motor was all stock and would fall off rail pressure on anything over 2800uS. Thats all with 1.9 60fts too

 

[quinton]

My 60'fts are in the 1.8's.

 

[quinton]

Ill put the vids up in a bit you can see I have bad hop when I launched at 15 psi or so.

 

[paint94979]

What is your.et and mph?

 

[quinton]

This was my quickest run last night. 81 degrees out.

Then this is a few weeks ago 60 degrees out.

 

[Subman]

With those split times you should be around a 13.1. A bad wheel hop will kill a good time. But I have to believe you have something else going on. Although a 1.8x 60' should be good enough to get you in the 12's.

 

[quinton]

Ya I know I just don't know what it could
Be that's keeping me from runnin 12's, and I just dot believe my wheel hop can make it run that bad. Just wish I knew more about tuning. My big tune is at 3200 pulse width with 28* timing.

 

[Trotorx2]

This was mine run last night. Best so far. That was against a new 5.0 mustang

 

[07bluelbz]

Damn nice run Ed. I guess you're liking the new tunes?

 

[quinton]

This was mine run last night. Best so far. That was against a new 5.0 mustang

What did you run? Can't get it to work

 

[Trotorx2]

7.6216 @ 81.66 1/8

 

[quinton]

Nice! Was it Pretty humid down there last night?

 

[Trotorx2]

Can't say about humidity but temps were in high 50's

 

[paint94979]

Why is the mph so low?

 

[Trotorx2]

I have no idea. All my slips show slow mph. I'm wondering if it is the tracks timing equipment.

 

[paint94979]

I think the timing is way off 7.62 in the 1/8 is an 11 second pass. I bet the mph is right but the ET is way off

 

[Evan@InglewoodTrans]

I think the timing is way off 7.62 in the 1/8 is an 11 second pass. I bet the mph is right but the ET is way off

I was thinking the same thing.
