Default Quickest/Fastest Stock Shortblock Subaru In The World, First In The 9s

Nobody can say you can't run a 9 second 1/4 mile pass on a stock Subaru shortblock any more.

9.9 at 139 miles per hour

Video includes timeslip:


Innovative Tuning's time attack car was built for handling performance more than straight line speed. Nevertheless, we took it to Empire Dragway in Leicester, NY for opening day (April 21, 2013) with the wing and front splitter off, drag tires on, to prove a point. Built and tuned properly, on decent fuel, with the proper supporting modifications, stock Subaru STI shortblocks are stronger than many people think. It's not power that's killing most of them, but poor or aggressive tuning, poor build quality, lack of/poor maintenance, and a slew of other issues. After multiple lapping days last fall and a race weekend with NARRA at Watkins Glen, this shortblock was far from new, but it got the job done.

The previous Subaru stock shortblock 1/4 mile world record was 10.49 at 129 miles per hour. We achieved a 9.9 second 1/4 mile pass at 139 miles per hour, shattering the previous record. With more time or a willingness to risk blowing the stock shortblock, we know we can do even better. We've since tested the engine and it's in good shape so this stock shortblock is being kept as a backup for time attack season. We will be running a built shortblock for time attack because the stock shortblock does of course have its limits and we'll be running upwards of 600 wheel HP sustained on road courses.

The 08+ spec STI OEM shortblock used for this world record pass was purchased from Subaru via our local dealer and comes pre-assembled. It wasn't measured/inspected or modified in any way. We used a stock engine gasket set including head gaskets with aftermarket head studs, head work/cams, and this car (1996 Subaru Impreza) has a stock 2006 spec STI stock transmission/transfer case.

You'll notice the delayed reaction at the light. This was on purpose as the drag truck in the left lane was so loud that I couldn't hear my engine and would have missed my shift points if I didn't let him take off first.
For more info, check out InnovativeTuning.com and facebook.com/InnovativeTuning

Thank you to our sponsors: The Driveshaft Shop, MSI, Kartboy, Boostcontroller.com

This car has:
Driveshaft Shop stage 5 front axles, pro level rear axle/hubs
MSI trailing arms, lateral links, rear subframe
Kartboy pitch stopper, front and rear shifter bushings, tranny crossmember bushings, short shifter, and front/rear endlinks

Congrats again. I wonder if the thicker 2008+ STi rods are allowing you to make a little more power safely?

Nice!

Thanks! That would be fun.

About 100-150 lbs lighter than stock. We added anti roll bars, suspension travel monitoring, Dccd interface and some other road racing bits since last weighing it, but took the wing and splitter off and put drag tires on for this so I'm not sure exactly how much under stock weight it was that day.

Haha
I mentioned it was 08 plus because of all the piston failures stock cars have had. It's also the block that people are supposedly cracking but this car, the actual drag car and others we've built have never had it happen.

In terms of mods, lots. I'm building to run unlimited class time attack so it has lots of bracing plus an involved cage, wide body, lots of suspension goodies and monitoring bits.

In terms of power mods I run a custom turbo and intercooler kit built at my shop with a 6765 turbo. This run was at 22-24 psi of boost with spikes over that. It made 521 wheel Hp on 21 psi, but I never ran it on my dyno above that. I'm confident it was in the mid to high 5xx whp range for most of the pass. The heads have upgraded cams, valve train and porting.

Got those shift points in the higher gears perfect! Good job.

What's the suspension data look like? Feel free to pm me, very interested.

Someone on another board asked me how long this would last in a street car and how much time I have on this shortblock.

I did a handful of drag passes that day so it saw around a minute at full power that day which isn't very significant in the grand scheme of things.

However, I ran this shortblock on the road course at TMP a few times and Watkins Glen in the fall, plus I attempted to take it drag racing over winter on my road course tires which was a waste of time since they spun like crazy. My logs show that even just one lap at the Glen is more time at full boost than my whole day at the drag strip. Intake temps also get hotter there and sustained high load and heat is rougher than short bursts like this at the drag strip. There's a section of the Glen where I'm full throttle for about 30 seconds straight.

It's hard to compare to street driving since everyone has different driving styles and habits. The way I drive on the street, this engine has easily seen 2-3 years worth of abuse if not more.

Carmi I briefly looked at the the suspension data. This was my first time driving the car with the ride height monitors hooked up and I didn't have the calibrations and names set up yet, but I'm looking forward to using it on the road course.

If you made around 580whp at 24psi your car would weight around 3050lbs with you in it to hit that trap speed .

You're assuming my driving was better than it was. LOL

I was 2 MPH quicker to the 1/8 mile on the previous pass at just 21ish psi of boost. Despite losing 2 MPH to the 1/8, the car was 4 MPH faster by the 1/4 on the 9.9 pass.

I can definitely drive it better. I hurt my 1/4 ET by about 2 tenths just on the 60 foot. I had a 1.41 earlier in the afternoon.

You also can't compare power to trap speed as gearing varies. For example, my 1/8 mile trap would be much better if I could use 3 gears instead of 5 to get there (07 gearing vs. 06 gearing I have). Peak power vs. power under the curve totally throws off any guess at power to weight. It's fun to guess though.

My car isn't 3000 lbs. It's a 96 Impreza to start.

yes I am assuming a lot of things haha. So how much you think your car weight with you in it?

You proving what I've always thought and I love it. If my ej22e build could hold up 365whp then my ej257 should hold 500+.

Subaru's Crack ringlands on 08+ because they run 13.7's while in FULLBOOST and knock there socks off. You don't hear about tuned cars having this happen as much.

I think you hit the nail on the head. I get really tired of people crying about how weak the subaru platform is. Then in the same breath rant about all the cheap modifications, tune, and poor maintence they do. If you want your car to run its best consistently you'll need to invest money into it and care for it on a daily basis. This includes buying qualiy parts, investing in a reputible tuner, doing ALL maintence on schedule, and monitoring the car's parameters such as oil pressure, knock, ect...

Great run! Awesome to see such results with a stock shortblock!

This is some very important info too. If this were a full weight GR STI I'm guessing the same power would probably be a mid/high 10 second car and trap under 130mph. Quite a difference the ~800-900lbs can make.

the reason it lasts is because HE knows how to tune properly.

The video has data overlay if you want to see RPM and gears.
I have a dry sump system for time attack.

Great job.....

What do you think it will take a full weight GR 2011 STI, power wise to run a 9.9 on street tires?

Great Driving Mike!!

Especially with the 06 trans, you lost a good 3 to 4 mph by shifting to 5th

Unrelated, but does that slip say the truck ran a 9.65? Christ the two of you are fast!
