11 Second Pump Gas Turbo

[nctsiawd]

Looking for Turbo's that have been used to get people in the 11's on 93 octane pump gas, no injection or nitrous... I'm not looking for opinions, just facts, if you have gone 11's on 93 octane pump gas, with no injection or nitrous, please post the Turbo you used, and how much boost you were running. A link to your timeslip would be prefered, but if not, just give your 1/8 mile ET and mph as well as your 1/4 mile ET and mph, and the estimated weight of the car.

Not me personally, but the guys from TPG tuning know a thing or 2 about pump gas runs.. . They went 9's on a gt42r (IIRC). Hit them up.

I'm sure power to weight has a ton to do with it, but my Summit a has gone 11.50's @119 on a 16G, FP2 cams, JMF Intake, Stock 2G exhaust manifold, 2G O2 housing, and the Auto. All on 93 octane, but the car weighs practically nothing.

As driven by previous owner:

Of all the diffrent setup's i have tuned the fp3052 has to be the most pump gas friendly turbo. At 25pounds with a 1.960ft it went 12.2. Easy 11's with a better 60ft

Some info in this thread about my old old old setup. http://www.dsmtuners.com/forums/drag-strip/73232-new-50-trim-pump-gas-record.html

Cliff notes:
FP Green
25psi, Shell 93 octane
AFC/660cc/stock ecu
Forrester intake manifold
HKS 272's

IRC FMIC

Keep in mind, this was in 2003. Hella old skool!

Anyone know what kind of timing these people running?

Haha crazy how far things have come since then, bu that is a hell of a run though.

Peak timing was around 8-9*IIRC

 

[bastarddsm]

Peak timing was around 8-9*IIRC

Sounds about right. Thats right about where mine sat on my WH1C, at 25psi, and I was trapping 116-117. My intercooler sucks tho.

 

[NOSLO2PT0]

9* peak timing? WTF? I was running 20* timing back in 03 on the stock ECU/AFC.

 

[JohnTSI]

The larger the compressor, the lower the IAT and the easier to make power at boost less required on pump. It can be done on a lot of turbos I would personally use something int 61-62mm range on the compressor side if I just wasted 11s on pump gas with plenty of room to grow.

I went 11.50's on my 68HTA. 22 psi boost and bald 17" evo tires on RE01R hard compound tires. With better tires and more than 1 day at the track I'm sure I could get 11.0-11.2's out of it on 92 octane. You can run similar times on an evo 3 16g and a couple tenths off on a big 16. 20g's will run about the same and TD06 20g's probably a little faster. My runs were done with a quick "street tune" the week before. We made a little more power on the dyno.

Sorry. 2003 Hella Old School? You crazy youngins.

Continue.

With a stock ecu/AFC combo, you didn't have a choice, you got what it gave you!

fp3052 24psi, straight 93

fp3052 24psi, straight 93

I've run my 3052 as high as 32psi on straight 93.

11-12* timing with a mediocre Buschur street core FMIC. I've decided 27-28 is where i like it on 93.

Never dyno'd with that much boost but laid down 370whp with 25psi and 7* timing (tuner was clueless, waste of $$). Car prob made 430ish on straight 93 @ 30psi with 12* timing if i had to guess.

I'm sure it helped that, back then people had good fmic's, not the junk ebay ones that everybody runs today.

I'll throw this out there if you're not looking to spend a lot of money.

Dollar for dollar, the HY35 is the best pump gas turbo mentioned on this page. The 11.14 @ 133 pass I listed in post #4 was done using a sub-$200 HY35 and an old-school cast Turbonetics manifold, TiAL F38 gate on the manifold. No more than $600 spent on the entire setup- turbo, manifold, and wastegate.

I'm sure there are some more expensive (billet, ball-bearing) options available, but if you want low-11's from an affordable journal bearing turbo that will take as much boost as your pump gas tune will allow, you're looking for a HY35.

 

[NOSLO2PT0]

Glad I got an HY35 sitting in the bsement waiting to go on next spring!

 

[JusMX141]

^ Definitely a good unit to have laying around.

Just to back up the HY35's pump gas effectiveness- Gabe's 11.14 @ 133 was done with a horrible 60ft from spinning the entire way through first gear (shown in the video). He recently ran a personal best of 10.86 @ 129, this time with a 50/50 mix of pump and race fuel....nothing else was changed. The 10.86 pass was quicker as a result of a 1.7 60ft, but the mph actually ended up a little slower.

Essentially the better fuel gave no real tuning advantage as the car still wasn't seeing knock with the HY35 using 93 octane pump fuel and a single Walbro 255 in the tank...even at 33psi.

 

[NOSLO2PT0]

Justin, what O2 housing did Gabe use? I'm going to have to figure something out for mine as well. I don't have access to make anything custom here.

He built his own using the five bolt non vband flange, by welding pie shape cuts to make the turn to clear the oil filter.

 

[NOSLO2PT0]

I'm gonna need one of those made for me, unless I can somehow find a 5bolt O2 housing made for a DSM somewhere.
