my wife let the leash off so i decided to take the car down to the track.. now, i am in hawaii so dont expect the times to be bad ***. As i was heading to the track i meet up with another evo and we BS for a while, and he wants to race me at the track, just for ****s and giggles. I am not very good on launching the car so that was basically what i came out here to work on, but damn if my times dont suck!! Just for some car info, I have a Apex N1 muffler (thats it), an intake, greddy type-s, and a dealership adjusted 23 lbs of boost. I am pretty sure that the ****ty times are partially due to the 23 lbs of boost, i assume its probably pulling timing at higher rpm. But anyways, here you go.

1st run:
reaction--> .556 (awesome)
60ft-------> 2.139 (****ty launch!!, this is my recurring problem)
1/8 et----> 9.121
1/8 mph-->78.37
1/4 et----> 14.106
1/4 mph-->99.98

this was with 7500 rpm shifts.

2nd run:
reaction .821
60ft 2.229 (terrible launch yet again)
1/8 et 9.140
1/8 mph 80.62
1/4 et 14.096
1/4 mph 100.65

this was with 6500-7000 rpm shifts (trying to avoid timing pull)

3rd run:
reaction .643
60 ft 1.941 (the launch was perfect!! but i missed 2nd, ****!)
1/8 et 9.3
1/8 mph 76.95
1/4 et 14.402
1/4 mph 98.51

4th run: (determined to make the launch and not miss second)
reaction .589
60 ft 2.169 (failed, launch was assinine)
1/8 et 9.171
1/8 mph 77.04
1/4 et 14.213
1/4 mph 99.31

so i completely failed all night.. on the other hand, my buddy was running no worse than a 13.6 with 100 mph trap speeds, his best was a 13.42 at 101 (not sure on mph), he has an intake, no back seat, and no muffler..
Someone please evaluate this, lemme know what the hell i need to do to get better times, and what you think i could be getting.. dont forget this is hawaii and its been said that you should subtract about 3-5 tenths of a second to adjust for a mainland time.

 

ok first off I know nothing about ajusting for a mainland time so I am just going to take your word and subtract .4 for evaluation sake...

ok first off reaction time... good you seem to be fairly consistant around .5-.6 perfect being .500

60ft... pretty bad... that 1.941 made you happy but you can still get more... I am running 1.8 a lot and I only have HKS RS and BR turboback... on the below run of 13.042 I ran a 1.9 which pissed me off being as I could have been in the 12's but anyways back to you... how are you launching????
so your best et would have been(according to the .4) rule 13.696 these are stock times from what I've seen but your launch has around .4 to be lost on that run... I think once you get the launching down you will be respectable for stock PSI but @23PSI i dont know.... get back to me on your launch

launch has been changing, but the 1.9 60ft i did a 5000 rpm feather, fealt great, and no clutch smell to my suprise. The first run was done with a blip at 4000-4500, and the others were bogs.

 

I would try 5500 I go to 6 and continuosly tap the gas pedal to keep it there... I spin just a little but I pull out 1.8 that was with 35psi in my tires though so if I drop it a bit I think I would eliminate my spin...

23psi with just a intake & muffler Dude, turn that down to like 21. Without supporting mods, 23psi is too much. Your timing and fuel are gonna be all outta whack. Work on your launch and you should be able to hit 13.5's - 13.7's. On the rare occasions that I do launch, tap throttle to build up boost, keep it around 6k-6.5k and slip the clutch. Slight smell but slingshot launches

 

Can you explain how a dealer set your psi on your turbo to 23? I don't get it. Did they install a boost controller for you? Do you have a boost gauge?

 

no i had a boost problem at one point, i was only getting 10lbs, and they couldnt figure it out, so the only way they were able to fix it was to put in massive hoses going from the wastegate to the solenoid, eliminating the boost pill, hence 23lbs. Now i have a case number and approval from mitsu for this correction to my boost problem.

 

Actually, a 1.9 60' time with a stock EVO is pretty damn good on that track. When I lived out their we called it "the Teflon track...nothing sticks to it!" When I moved out their from the east coast, with no changes at all in my Galant VR-4 I lost almost 2 tenths and half a MPH.... went from a best of 14.889 at 88.34 at Lebanon Valley raceway in New York (High 90's temperatures) to 15.052 @ 87.70 at Hawaii Raceway park (low 70's Temp)


You need a bost gauge NOW! It may just be spiking up to 23 due to the lack of the boost pill and then dropping to normal, but there is no way for you to judge without a boost guage. I would have the dealership put it back to 10 psi before I would run around at 23 psi myself....you only can get 91 octane **** water right? Or has that changed since I left Hawaii?

Oh, one more thing...was the guy you met Named Luke and driving a low wing white EVO? You need to hook up with him if you want to lear how to drive/how to mod a 4G63 turbo AWD car

Keith

 

haha, luke is my buddy, him and i hand out a lot. But the guy i am talking about his name is eric.. hes on the boards too, eric something or other is his screenname. And to clarify, i do have a boost gauge, and it was 23 and tapered to 20 up to redline.

 

wow. thats a quick fix if ive ever heard of one.

 

ok, update.. i thought about the times i was getting that night, and knowing that its pulling timing up top i really wanted to fix the excessive boost. So i had the stock lines lying around in the garage, and put them in, go f*king figure, it works just fine! So 18lbs of boost now, but it feels a lot better up top. Also, went to the track tonight, met up with my friend eric (evo) and we went up for head to head. He had just ran a 13.37 so i new i wouldnt beat him, but either way i still wanted to see what times i was getting.

1st run:
ME---------------HIM
reaction .661-----------.717
60ft 1.883---------1.934
1/8 et 8.664---------8.741
1/8 mph 77.96---------80.07
1/4 et 13.669--------13.699
1/4 mph 98.93---------101.85

so, much much better on the lower boost.. very close race, nose and nose! If you notice, the mph are higher on his side througout, could that be do to a higher rpm shift?? i was shifting at 6500, he was shifting at 7100. I am happy with this time, and feel that if my clutch wasnt burnt for that night i could have run better. My best tonight after that run was a 13.82 @98.40, so much better than before, launches are much better, but like i said the stock clutch cant handle much more.

on the contrary, it took them 2 weeks to figure this out, so there was some thought put into this.

 

I have a video of the two evos head to head from last night, not sure how to upload it though, can someone help me out?
