new timeslips for the EGTR

[Lex]

A 50 shot above 4500 RPM in 3rd and up should be ok

The 4g63 bottom end will take 10s ... for a little while at least.

ehh not really interested in nitrous too much of a pita

what! it will take 9's. seen it done for multiple years in a colt. stock at 30psi.

thats sick lol you were eatin up them muscle cars

Congrats, a 1.8 60ft is actually pretty damn good, especially for a FWD. Why does no one here run knock detection? http://www.viatrack.ca/

Instant subscribe to this thread, sent the link to bunch of friends.

The 11 second passes are amazing, but to smoke the big red neck trucks, which I hate them all, (they think because it is loud and are almost touching the clouds that it is cool), is just superb.

I started reading the thread and saw the 12 second passes, but the 11 second ones, my friend that is very very good in a car that you drove from your house to the race track. Seeing all those V8 tards smoked by a boosted 4 banger is simply awesome.

The crazy thing is, you know you can be part of the 10 second club, it is not a matter of if, but when... Like Bob Marley said " Time Will Tell"

Thanks for the compliments guys

As far as knock detection goes... I actually own a knocksense, but it didn't seem to do me any good so I took it out. Around 4k rpm it goes off even with the sensitivity all the way down, even at part throttle/off throttle. I had mounted the knock sensor in the stock location on the back of the block. All my boost/torque is made at 4k+ so... yeah. At the track I launch at 7k and the rpm never drops below 4k, so it would just be lit up the whole time.

Knock sense is useless. On highly boosted engines, you just need to run MBT up top for the mixture to ignite, there is no point to advance it too much. I'm pretty sure if you retard it a bit, you won't even see a difference.

[therieldeal]

i saw a definite difference (3-4 mph) by adding 1 degree of timing up top *shrug*

[323driver]

Can you repeat it consistently and then drop it by 1* and consistently loose 3-4 mph? Bet you not. Did you use the same fuel?

[therieldeal]

the track is always too busy to make a bunch of passes to try and tune stuff. i only got 6 passes in...

i ran one pass at 114, one at 113 with my normal timing

then i added 1* of timing and ran 116, 116, 116, 117. pretty damn consistant...

i did add a gallon of high octane (104?) just to make sure i didnt blow anything up. probably brought my octane up to 95 or so (from 93).

i may try adding in/pulling timing on the dyno, i think i get 3 pulls

[323driver]

next time, do it the other way, start with the higher timing and reduce it at the end. That way, track experience wouldn't count. I've spoken with some tuners and everybody seems to agree that once your mixture is good, the timing at high boost has less impact. Take the Evo X for example, it runs 20* timing at 21 psi but it also runs 9.5-10 AFR and therefore doesn't knock. By retuning the car to run 12-12.5 AFR, you have to reduce timing backwards by almost 10* but whether it's 10 or 12, it doesn't really matter, as long as it doesn't knock.

Anyways, the best thing is to try it on the dyno, hopefully I'll do it in spring once the setup is rebuilt.

BTW, did you ever find the drawing of the VJ23 dp flange? I'll need it soon to build a proper 3" dp and don't want to take the turbo off just for that.

[therieldeal]

well i can tell you that my 3rd pass (the first one after the timing change) was my worst launch of the day, and i still picked up a bunch of speed.

i'm running mid to high 11's AFR and like 16-17* timing i think

[323driver]

The launch has nothing to do with trap. When I did my best of 110 mph, i launched (if you can really call that a launch) at 2.5K rpm to avoid the clutch to slip. The times were **** though. Shifting fast at the right spot around 6K rpm is what made the difference.

I'm running less timing just to be safe since I only run 91 gas. And I've tuned as well for mid to high 11 at 23-24 psi (I only run 20 daily though) because of the cast pistons. With nicer pistons, you could go to low-mid 12 but I rather have a bit less power and have it in 1 piece than 10 more hp and a ventilated block.
