All I gotta say is wow and awesome build man!
I wish i could do something like that.
Im considering the meth injection as well to lower some temp

 

Thanks for the compliment! Its been a long project finally coming together.

Water/Methanol doesn't do much for N/A cars but on Turbo cars it works miricales. Prevents denotation, bumps your fuel to 116 Octane and then the Methanol gives it a nice little punch.

I put down 387 all-wheel horsepower that is 483 horsepower at the crank with out Methanol. Will be dyno'ing shortly with Methanol. Vivid Racing wanted me to break my engine in abit before continuesoly spraying Methanol.

I will be using Water/Methanol 100% of driving to give me the Octane Increase.

 

Well took her to a 1/4 Drag Strip and didn't do as good as I thought... The best I ran was 13.7 and 106mph. Now it was my first time at the track and I was having major hook up issues on street tires. Really hard to keep traction! And the air temp was 106 degress so I don't know if that was hurting the horsepower. Not a single car at the drag strip broke 13 seconds, I even raced a new Dodge Charger SRT8 and he only ran a 14.2 and I know that is a high 12 second car.

I'm installing the largest Methanol Injector AEM makes and re-dyno'ing the car today.

Anyone have any input on my bad 1/4 times?

Will attach links for everyone to watch.

 

Do you have a scan of your slip?

What was your 60ft time?

I'm willing to bet it was over 2 seconds.

Also do you have a ssk in your car?

Stock engine mounts?

Suspension?

Tires?

Wheels?

All of these will affect your 1/4 mile

4) Whats SSK?

I tried with and without traction control, no difference really. The car on the street is a monster, the few street races I have done here lately light to light, I smoked a new Corvette, a Modded WRX and 04'ish Lamborghini Gallardo. But I get to the track and she turned into a broken leg dog...

 

I know I was launching wrong too, according to my Dyno Sheet i need to shift at 6610 RPM and I know i was pushing it higher. 1st and 2nd gear i couldn't keep traction, just a massive burn out and I was nervous when i was at the light, I had good reaction times but i was shifting too late. But still I put 387hp to the wheels in a 2920lbs car, with me the car should be around 3230lbs. On paper that puts my car at 11.6 but in real life I should see 12.2 to 12.8 with real world factors. 13.7 is horrible for my horsepower. Even if I shifted perfect i don't know how much better it could have gotten. Like I said too, I raced a Dodge Charger SRT8 at the track, that is a 12.2-12.8 car and the best he ran was 14.2.

 

There are several factors including heat. Also if you could get your 60ft times down below 2sec, that would also help.

The M030 doesn't have stiff rear springs needed to help hooking up either for drag duty.

The 265 rears are pretty skinny to hold all that power. 295+ should be able to give you more contact patch to help with grip. Also lowering your rear tire pressures at the drag strip should help you hook up.

You might want to disconnect your rear spoiler harness too so it doesn't go up while you're going down the strip.

Do you have any datalogs of your AFR?

SSK = short shift kit

Also sounds like you spin in both 1st and 2nd. Maybe tailoring your shift might give you better hookup in those gears.

Going with lighter wheels will also help. IIRC, your existing wheels should be in upper 20's in weight. Getting some forged wheels around the 19-20lb range should help as well.

In my experience, the drag strip has a humbling effect on everyone that goes there as most always think they are really fast until they get there.

I wouldn't really let it worry you too much though as it seems like you had a fast car that night given the ambient temps and being able to outrun certain cars there.

I think once you resolve your hookup issues, you should easily be able to drop another second.

 

BTW, i can't really see your dyno sheet clearly on the phone but where is your torque curve and HP curve intersecting at?

 

Yes I have a Porsche Short Shifter Kit. I agree too that larger tires would help 295-315. I didn't mess with my tire pressure, left them at stock settings.

My Dyno sheet:

HP/TQ is at 330HP/330ft/tq @ 5200 RPM
Peak Horsepower is 387hp @ 6610-7000 RPM
Peak Torque is 348ft/lbs @ 4800 RPM

If you watch the videos I posted, she pulls hard and sounds great but just isn't hitting the numbers.

 

What do you recommend me shifting at? I have a G-Tech Pro SS, so I can go to a deserted road and do some practice runs.

 

I would try different shift points between 5500-6600 in various combinations for each gear and see if there is any difference. Obviously, you want to hold on to the last gear as long as possible to make it through the traps without having to upshift.

What is your AF Datalog and I'd be interested to see if the ECU is pulling back any timing due to any knock.

106mph trap speed seems pretty low compared to the HP figures you posted.

Do you know what types of trap speed some other comparable cars were pulling like the SC Camaro and SRT8?

 

Yeah i was shifting at 7000'ish, way too high! I do have all the Data Logging Software but dint record anything. I am running Water/Methanol to preventing "knocking/pre-det".

Right at the end of the quarter im maxing out 3rd gear. if i shift earlier at your recommended shift points I might be able to get into 4th before redlining 3rd.

I have a G-Tech, so i will go somewhere safe and do some practice runs.

 

Reason why I mentioned possibility of knock pulling back timing is you had an ok 60ft launch at 2.2s and assuming your 1-2 shift was decent without huge wheelspin and the rest of your run was ok, you should be trapping in the double digits given your hp rating. That's why I was asking if you knew where the other cars you were racing were trapping at seeing that they would have similiar or more hp than you.

 

I can look through my slips and post some of my competitions times. I was launching around 4000 RPMS, my Turbo builds boost starting around 3000-4000. Everything was happening so quick i didnt keep an eye on what my Water/Methanol was doing.
