Default went to the track this weekend

ok, so I had a total of 7 runs within about 3 hours so the car was kinda heat soaked. On my second pass i went 13.6 @110 picking up 25mph on the back half. This was my first night on the slicks. my 6th run was the best et of 12.8 @107mph, only picking up 19mph on the backhalf (1.9 60'). Then my last run was a 13.1 because I missed 3rd but did a 1.8 60', also picked up 24 mph on the back half. It was really hot out that day so I know that wasn't helping but. had the stockers in the trunk with the 24.5's on the front. I'm just looking for some opinions, without heatsoaking the car and missing gears, and a better 60' 1.7-1.8 what do you think the car is capable of? thanks

Generally what ever you drop off the 60' you can take that x2 off the 1/4! For example -.2 off the 60' = .4 off the 1/4. It doesnt always work, but it should be close!

Trap seems a bit low for a 50 trim, but don't take my word for it. I'm far from an expert.

If it wasn't hot and you can keep you mph up around 110 with a 1.8 60ft your looking at 12.5-12.3's. How much boost were you running and what type of gas?

21psi 93 octane, I had the dsp but I didnt even think to datalog 4 knock

oh, and some octane booster over a half tank. plus I had the stockers in the trunk, probably 50lbs I couldve shaved right there.
I was launching around 4900 on the 2step with about 13psi in the slicks. I had it set a blink higher on 1 pass but the slicks spun that run (probably shouldve heated em better.

What gear were doing your burnout in? If your doing it in first try it in second. What's your afrs? With you boost and a 50trim your mph looks alittle low. The rest looks ok.

the afr's were high 10's low 11's, although i noticed on the way home it jumped lean (like 12.3) around 5500 so probably running into a good bit of KR there. Only 1st gear burnouts and not very long 3-5 sconds probably. I'm thinking burnout longer, step the 2 step up a few hundred rpm's and 1.7 should be doable. just trying to figure if I'll be able to make my 11 second goal for 2009.

I noticed in your sig you have a Super AFC, then you mention having diablo. which device are you tuning with? If you are using the SAFC you could be knocking.

You do know they pull fuel by hiding boost from the PCM. Sounds like you need a tune bro. Heck If I could get 1.8 60' times I'd be running high 7's in the 1/8 and low 12's in the 1/4th.

yea, im on an afc because rage stopped doing email tunes and its a little hard to get time to go down there for a full tune. I bought the diablo while they were on sale. I know how the afc works and it doesnt help that im on 750's with no returnline.
You CAN pull a 1.8 60', all you need is slicks and the wot box w/ 2 step. Completely stock suspension aside from eibach prokit.

you don't need a 2step to cut a 1.8 60ft.... i cut a 1.68 60ft without one on the stock turbo. had other traction mods though like bwoody traction bars with h-brace, motor mount inserts, agp tranny mount, coilovers, front and rear strut bar. i was on 23in mandh tires slicks.

Agreed, I do a lot of 1.7-1.8 60 ft's and I don't have a 2-step. Just slicks and the motor mounts.. I have eibach springs but not sure how much that really matters.

You need a return line with 750's

I'm far from an expert but I would think all you would need is a fuel pump rewire and the injectors.

Bumb for somebody smarter than me.
