I cant see the DP moving 1/2 inch and hitting

I can.  Look how far the DP is from the center of the engine...    It only take  couple of degrees of rotation to end up with that 1/2"  And with two mounts they only have to deflect a little, each, to get that 1/2"

What mph...roughly. ...does the tranny shift each gear at wot? Is the 1-2 shift about 35?

Bring it up on the graph or gauges. What's it say?

[Shimy87]

Thats what it looks like to me and I think that shift is my knock. It jumps to 10-14knock In like 2 frames on that shift point. Ordered my new chip with knock ignore up to 35.... should have said 40.

[Shimy87]

Chip is supposed to deliver today, Nitto NTO5R's are supposed to arrive Thursday, race day Sunday 

[Shimy87]

couple of runs with new chip, ran out of time. one shows some knock but don't think its real, made second run with same settings and it was clean. still real rich.

02's check in right around 800 at the end of the run. 102 mph tells me that wasn't a 1/4 mile pass...somethi ng less. I'd expect about 112-113 mph. Remember...the further you go...the leaner it gets. Same conditions...a nd a full 1320. I'd say about 770-780. Erics pretty damn close. I can't tell what your 02 readings are at the shift points...cuz you slowly leaned into it. You'll likely have to pull low gear fuel...but that's just a guess. You'll have to make a run from a dig...and then have a look at the low gear fueling.

fun time today..best I could do was 12.1 will post slip and logs tomorrow. Short times were really good for me, 1.6 but still low on top end mph 107ish

[TexasT]

Does it have a fresh fuel filter? I would be looking into some stuff with that 107mph. Something ain't right.

[Shimy87]

Yes...new.  going to check compression tomorrow.

log of best run, and slip times
60 ft 1.651

1/8 mph 88.36
1/4 12.135
mph  107.34

Your full low gear timing doesn't come in till 11mph...which leads me to believe you haven't got Erics chip in 'aggressive' mode. Low gear fueling comes in around the 820's. High gear fueling comes in at 780's.

Drag the low gear 02's to 770-780 and take a couple points of high gear fuel out of it...and set Erics chip on 'aggressive' mode. You'll crack the 11's on the same launch and weather conditions.

What size rear tire are you running? 26 or 28?

You're getting a decent RPM drop on that convertor.

[Shimy87]

Thanks Brad,

I thought I did but probably set it wrong, I have setting 3 at 129, thought that was the aggressive setting?

The run before I did have high gear and low gear set one number lower and got knock, so I put high back up one, left low alone and got that run.

My tires are 26 3/16 tall. Nitto NTO5R's....they really hook well.

Really thought I would get in the 11's, that's my goal. I cant see my 60 ft getting that much better, car dosent seem to MPH out the end like I thought it would? Is it the short tire that is hurting me on the big end?

[Scoobum]

Off the top of my head number 3 is low gear timing. Eric says under 35 mph there is no delay. Check your file. Looks like full low gear timing comes in at 11 mph?

[Shimy87]

I agree on log......how do I enable aggressive timing mode....the instruction dont say but I remember reading somewhere you set #3 to 129.

Your thoughts on 26 vs 28 tires?
