It's an AUTO = no drop in boost when shifting

[DeepBlueGXP]

He did have DRs I believe they're 10" wide and his 60' is below 1.9.  I'll see if I can get him to post here.

WOT Box does almost same thing for manual and you shift when you want

Joe: you meant under 1.5s on 60ft, right?
I have seen reports with street tires doing 1.8s, I did 1.9s with factory tires and based on my math he needs to be around 1.5s on 60ft to do such an ET.

[DeepBlueGXP]

I said below 1.9 because I couldn't recall what it was.  I sent him a PM and he was on last night. 

[LatinVenom]

I know what he did but he send it to me on a PM.
I will not post unless he gives permission to disclose what he PM me, sorry.

Thank you for tip Speedracer,

I used once Toyo R888 at the strip, and I test them at 21psi - 17psi - 15psi - 11psi, best 60ft (1.95s) was with very low pressure.
With Bridgestones RE050A Pole Position from factory I managed 1.98s.

I can't afford to buy 10" wide rims for our cars, 2 of them costs around $1000 here.

The only viable option from Mickey Thomson ET Street Radial II is 245/40R18 but I would prefer 245/45, I know higher sidewall has a great impact on launching. But there is no such thing from MT / MH / Nitto as drag radial, they all have 245/40/18. 

[speedracer69]

here's the part # 3782R P265/40R18 27X10.50R18 from mickeythompson web site. You can try any tire in the world and nothing will be close to the Street E/T ll, unless you have 450 to 500hp to the wheels, and you run 15in wide slicks.

Will 265/40R18 fit on a 8" wide rim? Because they say is for 9.0-10.0 wide rim.

I looked at that 2 months ago and my tire dealer said they wouldn't do it, not that it wouldn't fit, but they didn't want to take the risk.  The biggest they would go on a 8" rim was a 255/40R18.  I since then went staggered with and have 275/35R18 on 9" rims on the back.

Since they were just installed I don't know how they will affect my times yet.  Test and Tune is tomorrow so I'll see and report back.

[Kelu]

Wow, nice, good luck!!!
Looking forward to your new results, please don't forget to report.

I think that 8" rim is pushing it 8.5 to 8.75in might work but that would be the minimum. The tire will bow up too much and you will loose contact surface.

[Kelu]

Thanks for the answer, so in my case the only option is MT Street2 245/40/18

It's going to be a while for that report.  I was out on a deserted road this afternoon testing the car for the track tomorrow and I blew the engine.  Misfires on cylinders 1 & 2 with plenty of white smoke.  Will begin the engine tear down tomorrow to see how extensive the damage is.  The car was running really good before it went though.

Ouch!

Speedy recovery!

[Kelu]

Ouch, good luck fixing it and we hope you will get back soon.

[LatinVenom]

255's should work also, but did not check to see if they were offer in that size.

[Kelu]

I couldn't find good drag radials on 255

Things that can help you are: Use AMSOIL throughout,

AMSOIL? how come?

index sparkplugs,

What is that?

take off front tag

Hmm, this might help for a Sol because is blocking IC but not for Sky/GT

cut open airbox,

Already did that, I have one of the most open aiboxes

If you have 450 to 500hp to the wheels you can get 1.6 to 1.5, that's the only way to get there tires will not help you.

why stick with DRs on 450-500whp? If the track is good why not go with slicks? 1.5s or 1.6s with over 450whp seems high in my opinion.

[HAMMER DOWN]

AMSOIL? how come?

IMO the best OIL ever made at this point and time.  I been running it threw out my cars (motor,tanny & front & rear Diffs) for over 5yrs.  0W-30 SSO & Ea filters.OCI is 15k & my Subaru 2.5L turbo as over158,000 miles. Running 16.2 psi of boost with original motor & turbo. My Sol. GXP 2.0L turbo over 57k there's no Ea filter for the Sol. so I change it out every 5k. & my G\F's WRX 2.0L turbo over 118k. with no lubrication failures.

AMSOIL? how come?

AMSOIL, SMAMSOIL.    Synthetic is Synthetic.   Stick with what you have, I can tell you Speedracer has been draging for a long time and back then the only good synthetic was Amsoil.

What is that?

Like I said above, he's an experienced drag racer and has several vehicles.   Even has a Dodge SRT-4 that is setup strictly for drag racing.

[Critterman]

Joe, Let me know when you are going to try this (indexing)  Wonder what plugs we would use in copper?  since our plugs are in the center of the head, I wonder how much difference it would make.  GXP and N/A would be different I think as the fuel comes in differently with the DI

[Kelu]

Thanks for the help guys  

I use Motul 300V 100% Synthetic, is best rated oil around here and not only here. I never had problems or heard somebody having problems with it. Sounds to me same as Amsoil, I can't find Amsoil around here and I will stick with Motul. I don't think there is a big difference between these two.

GREAT TIP ABOUT INDEXING, I will inform my mechanic to do that when I will get my car for turbo upgrade. Maybe I will ask them to do a dyno before and after because they have the dyno room right next to garage.

[Graywolf]

Kelu, I agree with your excellent choice Motul 300v, there are many excellent oils. The guy that works on my car runs in the mid 6 second range in the 1/4 mile and swears Royal Purple is the best.  Most synthetic oil in the U.S. only has about 5% synthetic oil in it.   I use Redline for engine, trans and diff.  Last weekend I saw the first funny car built,also the first funny car that the entire body lifted up, also three famous drag cars-"The little Red Wagon, The Chitown Hustler and the Californian " Heard he paid half a million for the Red Wagon. Also saw many rare dodge muscle car hemi's. All in a private collection about 2 miles from my house. I use astroglide at night  if I get stuck

[Critterman]

Motol smells so good, leave it to the French to perfume their oil

[Kelu]

Thats cool! Yes, I can stumble my way though hpt logs

Where did you get the product? and how does it work? Because I am a big fan of the launch control idea...however I will need a clutch that can take the abuse first... stock wont like the slam & burn.

So you have your launch control set at 2850 RPMS? have you found that to be your best launch RPM? (I will be hitting the track soon:))

google WOT Box

More info about it:

The WOT Box adds two major features to any car. They are No-lift shifting and 2-step launch control.  Both of these features are completely user-programmable using the WOT Box Graphical User Interface.

The No-Lift Shift feature makes no-lift shifting easy by cutting your engine's ignition for a very short period while you no-lift shift. No-lift shifting is keeping the gas down through the shifft. The ignition cut allows the synchros in your transmission to mesh easily, reducing the chance of missing a gear and damaging your transmission. Keeping your foot down through the shift also allows you to hold boost through the shift, thereby significantly improving your E.T.

The major benefits are:
Lower ETs
Reduced chance of missing a gear
More consistent, effortless shifts
Reduced wear on the transmission
Reduced chance of major transmission damage
The 2-Step Launch Control modulates the ignition by cutting power to individual ignition coils to hold the RPM you want to launch at. The turbo will spool up while you do this. You can use this feature for a more consistent and more powerful launch in boost!

I raced my stock clutch for over 300 launches and over 15 000 miles in 2 years, until I installed nitrous and doing HUGE torque I didn't had problems with it. But a better clutch will definetly help, just installed SPEC 3+ Stange Clutch and SPEC flywheel (Non-SAC).

What you saw in the logs is not actual setting for the race, the logs were done just for show off purposes. Launch RPM depends on traction track/tires and varied in my case on our crappy strips from 3000rpm-4500rpm. Basically you go to the track with low rpm launch like 3000rpm and work your way up, if it bogs increase the RPM launch, always check your 60ft (don't listen your sense if you are a beginner).
For WOT Shift is same but decreasing the time from 0.4s (default) down as low as how fast you can change gears, I went to 0.2s on good strips. This WOT Shift will kill your clutch more than 2nd step LC but is more beneficial for ET than the LC. Also WOT Shift is safer for the gearbox and reduces the chances for miss shifts.

ALWAYS log the races with HPT (recommended) or any other logging software, I would use race gas in your case at strip just to keep that engine safe while you push it.

Drop your pressure in rear tires in mod/test way, I found best performance 15-20psi with street tires and inflate front tires up to 45psi.

TEST / TEST / TEST - that is the key, try to find a track not busy to allow you at least 10 runs in a day to be able to work on the fine tuning.

Oh and a special advise for you: PATIENCE BUDDY
