pump gas limit

[bastarddsm]

, some people consider pump+meth, just pump. I don't, but each his own. Anyway you look at it, these pump gas hy35 guys from out east got us all beat by a long way, so all of you in this thread are doing it wrong.

 

[Archer Fabrications]

where I'm moving (which is east) has 94 octane pump I'm gonna try and push the hx40 there. i don't care who says it but pump+meth, is NOT CONSIDERED "pump gas" in my book. especially since formula 1 use methanol as straight fuel ( another type of race gas) so no, methanol does not constitute falling under a pump gas tune, the stoich afrs are even different.

Just wanted to update my best pump gas performance.....

After installing a JMF Drag intake, and upgrading my Fuel system.

Last time out I logged 71.8lb/min of airflow on 93oct pump gas (Shell V-Power, no ethanol added) and no meth injection.
This was in 36* outside air, at about 31.5lbs boost.

I realize the low air temp isnt typical driving weather, but hitting 70+lb/min air flow on pump gas is really awesome no less! Car felt REALLY Good!!!

That amount of flow hints at power into the mid-600awhp range.
Lets you know what kinda power is possible with a good quality/complete set-up

Is that with or without the meth injection listed in your profile?

No meth injection.

If your using dsmlink estimate your airflow has to be calibrated correctly for that to be accurate, so if your boost est isnt matching your map you habe inflated numbers.

Hold on a sec, did you buy jack's gsx? I see your to4z, racing hart rims and other mods in your profile. i hear great things about that car from jack. He built my motor too, and your airflow is prob correct with that monster.

I helped drop in your motor

Yeah was Jack's car.

I'll post a log later tonight

Haha nice!

I wanted to race that car cause he always talked shit on my hx40 what are you hitting in the 1/4 now? Heard younwere running outlaw class.

We've got a local 1g @ 612whp w/ 92 octane no meth. Daily driven tune. The limitations are in the tune and setup. Every car will react differently.

 

[NewTurboTuner]

Heres a copy of my very last log. Its a 2nd through 4th gear pull.

The tune is done by me. Im still learning & it needs some adjustments (I haven't driven the car in a few weeks, so haven't had a chance to finish the tune) ...power potential is there non the less.

 

[Archer Fabrications]

I like your timing map, i might give it a shot, you think your numbers are low you shoukd see my peak at full boost. That t04z is pushin some air! Its not even close to its max 85lb a min! Jack never showed me his tunes so its good to see how it performs for once with a different tune.

It didnt use to run any timing when I got it (i mean none ).

For a 93oct pump as map, yeah its kick ass!
With e85, and Race Gas it would be sick!

 

[Archer Fabrications]

Uh well i get -6.6 on spool and peak to 2.2 at 7k ....... Maybe you could help me out if i sent you a log im on 94 pump

 

[Black95TSIawd]

Are you seriously running 2.2 degrees of timing at 7k? You're EGT's must be through the roof!

 

[Archer Fabrications]

I dunno i dont have an egt sensor. The manifold isnt glowing or anything. Iats are low, and coolant temp is 200.

Its a 69lb a min turbo its blowing cold air. Not saying its a good thing at all.

I need to know more about this.

I'm at 42psi on a 94 octane and meth with a 3586hta, almost 80lb/min. no knock

Is your SD table calibrated properly? 80lb a min sounds nice haha when do you reach said 42psi


Get out of here with your methanol, this is a pump gas thread

 

[paul s]

20psi at 3960rpm, 42psi at 5200rpm. 80lb at 7700rpm. yes the sd table is pretty close. the title says pump gas and I'm on pump gas

And methanol. Post a log i gotta see this

 

[paul s]

there you go, here is the log at 42psi

thats really impressive. i cant wait to get a 3794HTA


why was boost dropping from 42 to 39, that sool is amazing. damn, that turbo is much better than the HX40 at same boost level

and you got 1.8* knock, nothing to worry about. but its not no knock.
