10 Seconds On Straight Pump Gas

[super95awd]

Operation 9s on pump is underway. Here's the big mess we've stirred up so far. The gauge cluster is going to be replaced by another piece of aluminum with all Autometer gauges, just cause I feel like it .

Hey, would you want to sell the black passenger airbag cover by any chance?

Thats a great point and somthing alot of people are overlooking. You dont need to make 600+awhp to run into the tens, hell Curt did it with just over 400. The car has a great drivetrain and a pretty damn good driver.

I've also found over the years that a bog off the line kills the mph, while tire spin yeilds higher than usual mph, but both situations seem to net the same ET.

I think with a better launch the car would have run a 10.55 or so at 131-2mph.

You'll have to ask Andrew about the fuel pressure, I think is was a bit higher than that.

Curt is a great driver buy that car is also alot lighter than most evo`s out there.
I would guess that this car is rather light also.


I went 11.7 on pump gas with a 16g and very little time spent on tunning so i am not sure what so unbelievable about this.
The bar is constantly being raised.

 

[super95awd]

The car wasn't very light at all when it made that pass. Trust me.

Dash is shaping up...

Woot horay for the haters!! anyway I don't think congrats really says anything right now honestly. What you have done is simply amazing, a good friend of mine was hoping to have one of the only full weight 10sec pump gas awd but I guess we will have to be the first on 91 . Keep up the good work bro your going to need it for 9's on pump.

 

[Metrzan]

hey Andy next time I'm in town your gonna let me take that thing out right, I'll just have to make sure I time it right so I know its together.

 

[Staytuned]

Nice dash Andy. What are you planning to weigh in at next time out?

 

[92lzerNA]

Have you thought of entering in Hot Rod's Pump Gas Drags. Sure you have no chance in winning because the fastest cars run high8's/low9's but the the majority run mid 10's.

 

[super95awd]

Thanks for the comments guys. My parts orders keep rolling in, I'll have some more picture updates soon. That pump gas drags thing would be real interesting. There would be some unhappy V8 guys after that one.

4G63-GST --- I've done the majority of that aluminum work. I had the holes for the gauges punched by a local shop. To tell you the truth, 95% of that aluminum came from a "Rent Due Today" sign that somebody chucked in my friend's yard, . If you need the factory cluster I guess I would be willing to sell it.

Oh and Steve...I'm just hoping for something light

Reading thread with a lot of interest.I have just about got my new FP3065 /2.4 combo up and running and reading your thread and times gets me excited that my car should
really fly.
I have mostly similar mods with 950s,jm fab intake and crower stage 3 cams.
I do have an water/alco injection system that might install or might upgrade it first to the
electronic controller they have out for it now.
I know a guy on our local canadian board running an fp red at 24psi daily on pump 91 or 92 but he has water/alco injection.
That timing does seem high and tha afr seems a bit lean for pump maybe too but hey if it works ,it works.
What tires were you on..?
If I stick to street tires like firestone fuzions do you think I can keep axles and tranny together if don't dump the clutch.
I do plan on better axles and trans and center diff next year likely not sure have any money left to do it this year although you never know.

I will be thrilled to get mid 11s out of my Fp3065 on pump..was hoping for 10s on race.

 

[super95awd]

I was on BFG drag radials. Traction with regular street tires would have been a lost cause. Best of luck man with the setup, it should definitely move.

 

[MrPikolo]

Wow, congrats!

Naturaly, I'm kinda sceptical. I'm VERY suprised you arn't running meth injection. But, time will show. It will be an inspiration to us all to run 9s on pump with a dsm. Are you doing any sort of weight reduction? Noticed you didn't have a wing on there. Do you have an idea of what your are weighed at? Be interesting to know if you are near a "street" car weight.

 

[zdrux]

Too bad you were running the MAFT, I would be really interested to see proper airflow numbers from your dsmlink log (because you said they were off a bit).

Was your base timing changed at all? Maybe retarted a bit to give more room for increasing timing up top?

And any idea you could share the intake temps with us, or was that never logged? Maybe just give us the ambient temp. on that day if possible?

 

[Staytuned]

Weight here Here is the weight of the car with the time slip.

Again, no one is bitching about "x" power = "y" et, but just the tune to make the power on pump gas. If it was at 23-24 psi in would still be to the contrary of years of tuning for many DSMrs. You'll also notice a lot of the guys calling bs are the one that run/tune with DSMlink. I don't care what wheel you are running either. The boost and timing don't go with normal pump gas.
I sit at -3 to -4 on the timing sliders to run 23-24 psi on pump gas. Thats a 67mm compressor, that is surely pushing cooler air at 23-24psi versus at 3052 at 28psi and choke flow. I also run a much larger turbine housing and turbine wheel.
I have tuned a dsm that was on pump gas where I was going posative on the sliders before. Car went through some 20+ dyno pulls. It also grenanded a plug on the way home becaue the knock sensor was disabled w/o my knowledge. That was about 23psi and 11.1-11.5 as well.

apparently.....YMMV

Good driving, good time, good tuning. Congratulations!

To all the disbelievers:
You're missing a piece of the puzzle. Instead of saying 'it can't be done' why don't you ask 'what's the secret?' Then someone might be inclined to reply with something like,

There's more to tuning than just A/F ratio and timing. You can add a good ammount of knock suppression by detailing the combustion chamber. Everything should be smooth, and maximize the quench zone. A stock head has too many flaws due to the realities of mass production.

Oh BTW, Nice Job! This gives me a goal to shoot for with my new setup. Keep up the good work!

Then somebody might repsond like this
"if the headwork is so perfect, why does it take 28psi on a fully built stroker to make 500whp...."

I'm done here. The car is well built/fast regardless of what I say.

 

[zdrux]

Can we know:

1. Who picked out the parts
2. Who assembled the motor
3. Who tuned it

It obviously seems like the driver did NOT build the car since asking questions like what the fuel pressure was at, the response was "I think it was 45psi" .. when you run a 10sec car, you don't *THINK* what your fuel pressure is, YOU KNOW. So I`m just trying to figure out if there was anything special done, or any tricks or tips we can get from whomever build or tuned this car for the rest of us..

I`m also interested to know what temperature outside was.

 

[super95awd]

Alright, lemme answer some questions. First off, fuel pressure is not the most important part of the equation. I do however know that it's somewhere around stock, maybe up near 45. One thing that everybody is missing is the fact that we were running 95% duty cycle on 1000cc injectors and still seeing fairly lean AFR's for pump gas. That's a LOT of fuel. I picked out all of the parts and have done the majority of the work on the car. Natedogg built the motor and it is currently apart and being rebuilt with Manley rods. Remember also that there's no secrets there either. We have about the most unscientific engine building procedure happening in about the messiest garage on the east coast. Nate also tuned the car, and the hilarious thing is, from a completely base tune, we made 2 tuning pulls on the way to the track, and that's what we ran the 10.8 on. Intake temp readings with the DSMLink are worthless because the translator locks them at 80 degrees. Ambient temps that day were somewhere around 65. We have all kinds of cool new toys sitting around either waiting to go on, or in the process of going on. The car will be nasty when it's done. Operation 9's underway.....

Get the fuel trims right and the Maf-t calibrated and your duty cycle will drop a lot. You can't be maxing out 1000cc injectors at your level unless things aren't calibrated properly or your fuel pump isn't supplying the necessary fuel

Or the injectors aren't flowing anywhere near 1000cc/min.

Andrew, have you had the injectors flow tested to verify they are 1000cc?

 

[GVR4592]

A lot of people on the Dsmlink forums have this problem when using the MAF-T. They max their injectors out at a rediculously low horsepower level.

Yes, but when that happens you should also be running extremely rich. I was also maxing my injectors out at ridiculously low airflow due to the MAFT, but I was also running 9.0:1 AFR's at the time. He is running 11.5:1 AFR's. That means he is definitely maxing his injectors, or his fuel pump cannot keep up.
