Max power on pump gas

[chad b.]

Before I purchased my RB, I was building a KA, so I posted on ka-t.org. They pretty much have a running tally of top pump gas dyno numbers. So, I was just wandering. What is the highest pump gas numbers on RB's? Maybe we can get some dyno numbers from people and their motor setups to give an overall idea of what can be made on pump gas. The last time I checked, the pump gas record for a ka-t was 535 with a billet 67. If not, we at least need a dyno thread.

[Carl H]

not gonna lie this is a silly thread...

dyno numbers are worthless, only good for boosting egos.
a dyno is a tuning tool... used to measure changes in response to the tune.

what is your definition of pump gas?
octane rating?
brand?
current mix in the tank?
tuning?
dyno type?

[Largekid]

does this count with help of meth too?

I don't see what's silly about it. A dyno is a good way to compare numbers as a bench mark. Everyone knows a Dynojet gives liberal numbers while a Mustang dyno give conservative numbers, etc. etc. I didn't say big dyno numbers means a fast car. I've been building and racing cars for 16 years, I don't need a lesson on what a dyno does. All I'm saying is that it would just be nice to have a dyno thread on here to compare numbers with different setups.
What is my definition of pump gas? Well, that would be unleaded GASOLINE you buy at the pump. It usually comes in 87,89, and 93. As far as mixing, there is no such thing. Anyone who says they're running a pump gas race gas mix if full of sh*t. Leaded race gas is heavier that non-leaded pump gas which means it's going to settle at the bottom of the tank where the fuel pickup is. You can mix it, but it won't stay mixed for long. VP has a write up about it on their website for anyone who wants to argue. As far as tuning goes, that's what will be interesting.

[Gabes13]

I lived in a town that had unleaded 101; crap was almost $8 a gallon.

[eh?]

My RB25 did 507whp @ 20psi on straight pump before our tuning session was cut short. The tuner said I should have made about 50whp more. Turbo got hungry and ate a hose (tuner left the air filter off) This was a basic build with stock CR, untouched head. Made power all the way to redline. Turbo was a 6765 .
After repairing the turbo I did run 26psi while street tuning.... no problems.

I know XS engeering has made 7XX on a pump gas RB26 before.

[StricNyne]

i run meth and ultra 93, i am selling a labonte meth kit, brand new for 250, it cost 320 on their website

but large inj and a good fuel pump can dump the insane amount of fuel you would need at around those high numbers

507 with a stock head and cams on pump gas. That's what I'm talking about! What engine management were you running?

[Krazykouki]

Chad, can you be more specific? What was done to the bottom end? Stock head gasket?

[Cjmartz2k]

Our pump gas is ballpark 95-96 Octane and there are 800-900+ hp cars running on that over here. No meth.

[Carl H]

you guys are also rocking the RON number only, where us its (RON + MON)/2...your 98 is akin to our 93.

for arguments sake i'll post mine, just to prove how silly a peak number thread is:
93 octane from BP
396whp @ 22psi out of a gt3076r on my rb30, stock ecu...full tune.
dyno dynamics dyno

[StricNyne]

how much torque on the 3 litre !!!!!!

[flatrate]

i made 412whp on 20psi 92 octane, thats with a massive boost leak on a 3076R, need to redyno / retune... id like to get 500whp on pump gas...

my motor is also rocking stock cams valvetrain etc... i revved it out to 7500 and it was still making power

Eh? was running an AEM EMS

Im running haltech

I was actaully converting it already. The posted numbers are 102 octane IIRC.

I'd love to try your set up out on some of the tight and twisty back roads we have over here. It must be a handful trying to keep that much grunt planted

[StricNyne]

in japan is rb30 common ?, i heard they are big on the 2.8 strokers out there

map based AEM.
I wouldn't be surprised if I had gotten 600whp on 22psi with 93 pump.
I made 537whp on a smaller turbo with 22psi and race gas. The stock cams never showed any signs of losing power at the higher rpms and torque held all the way to redline. No doubt new cams will help power but I have shown vtc will make power at the 500whp level and vtc makes a significant difference in torque in the mid rpm range.

[StricNyne]

yeah, i look on the aussie forums of people making good power with stock cams, thats why i never did cams on my motor but i did valve springs, i also am debating on getting a spare NEO motor

[chad b.]

Awesome, keep'em coming. I remember the pump gas record for a KA-T was like 535 with an AEM and a 67mm. I remember one dude made 520 something with a GT4088 on pump. So with the right parts, these motors can make enough power to destroy their bottom ends on pump gas. That's pretty awesome. Since my goal is 525whp for now, I think I will just build mine for pump instead of E-85.

[ItzGenX]

525whp shouldn't be too hard compared to the rest of the world. Our 93 octane may seem like a low octane number compared to Europe and certain parts of Asia, but if you take their 98/99/100 RON fuels and add with a much lower MON number then divided by 2, it should be right around where we are at anyway with an AKI of about 93/94. The problem would be if you are stuck in an area with only 91 octane. The lower areas with 91 octane should still be able to get you into the 500 barrier though.

[chad b.]

We have 93 here.

[ItzGenX]

We have 93 here.

Then you shouldn't have a problem with your power goals in the octane department . You'll just need a nice tune, and then you are set.

[Cjmartz2k]

Super rare. From the sounds of it, even less common than it is in the states. It's an Aussie only thing I guess. They do like the little extra gain in displacement for huge sums of money strokers here though. My buddy just split the crank in his HKS 2.8L stoker not too long ago.

[Carl H]

ah, ok...yeah depending on where you are the octane rating changes.
as far as torque output the engine makes far more torque than hp, its rather odd tho why it does...but it does.
iirc at around 376hp it was producing 420ftlbs, so at 396hp i remember it being alot closer to 450?ftlbs.

power delivery is actually rather smooth and easy to control thanks to the 30r being some what 'small' for the 30, 1st gear is the only gear with real traction issues.
the way that my car is setup it grabs traction quite well at lower boost levels but on high boost it struggles where occasionally it will only hookup mid into 4th.
its rather fun to drive on twisty back mountain roads, went on one this weekend and most of the time was spent trying to keep the tail end straight!

ARGHHH the more i hear about the 30 the more i want to build a spare motor f*** torque is insane !!!!!! what intake did u make that torque with ? the rips or another ? i gotta read thru your build threads !!

It's getting an AEM, and I'm gonna have Rolo at CentraFloridaTurbo tune it.

[eh?]

Talk to Alpha on tamparacing, he tuned my car and he knows RB's and the aem. He can tune it at Titan (extra $$$) if you don't want to go to Tampa.

[chad b.]

I know John (Alpha). I've met him several times. He's a big Honda guy. Nothing against him, he's cool, but if I don't get it tuned locally, I'm taking it to CFT.
