We turned up the boost on John's s2k to 26lbs with 100 octane. It is a non-ball bearing GT35/61 t3/t4 turbo. It is still the stock motor with our 3mm headgasket. After we finished dynoing it we took it out on the highway and in 4th gear at 65mph the tires would still break loose. Because of the time of year here all the tracks are closed so we can't run the car until the spring.

The motor has about 44,000 miles on it and we feel that the stock engine is capable of handling 600hp to the wheels. Honda has done an excellent job on this engine.

Enjoy!

 

#'s are impressive...but damn i would have the thing breaking loose on me that easily, guess thats what comes with higher torque though...cool stuff!

 

thanks for sharing

 

Holy ****, look at the TQ curve Smooth as my ***!!!!!

 

yeah great power curve for sure. i hope that thing is running an engine management system.....

 

Wow

 

all on a stock engine, bad ***..

honda engineers,

F-in genius'

 

NICE!!!!!!!!!!!!!!!

Im interested to know as well...

 

Keep us updated on how long it lasts at that power level

 

i like that TQ curve

 

dang those sleeves hold up that much power ?

 

Will that boost level be used @ the track only? Whats the street setting ? See I said I wouldn't boost the S, I had my civic for that, Now Im thinking of changing my mind ! DAMN! ! ! !

Good #'s

it's the inline kit. i'm asuming he would be running the 18psi on the street.... for roughly 450rwhp

 

video would be great

 

once again inline pro get a for the kit. I really want to know how long will this motor last boosted. From the pictures of the F20C or F22C. Their sleeves look super thin as hell.

i think this car that they did this number with has been running at 18psi for quite some time... i've heard they've been ******* it for around 8000miles... or so.. .maybe even more now.... keep in mind this 520rwhp number is with 100 octane gas.... i'm really not to impressed with it... looks like lots of tuning must be done....

i mean come on... at 18psi with 93 octane you're pushing 450rwhp.... you just raised it 8psi and you're using 100 octane and you only get 520rwhp.. ehhh... i hope they aren't still using the vafc... please just upgrade to an aem ems and you'll see that number rise a lot higher then 520rwhp at 26psi

 

it's impressive that the engines guts can
handle that much power.

the octane is only going to keep detonation at bay,
you can do that with any motor.

but stock rods holding together at passed 500whp on an engine
designed to be n/a, that's really cool.

yeah. but it's not that surprising.... keep in mind the S has forged pistons and rods from the factory.... so i would asume the only thing that would likely need upgrading or would be good to upgrade are the sleves...

You sure about that??? What exactly are they forged out of since they can't be aluminum becuase of the FRM sleeves. S2K's do not have forged internals

 

here are the specs from Honda. It states "forged"

8000rpm rev limit
240 hp @ 7800 rpm
162 lb.-ft. of torque @ 6500 rpm
0-60 mph acceleration in less than 6 seconds
Compact, lightweight engine design aids in ideal (50/50) weight distribution
FRM (Fiber-Reinforced Metal) cylinder liners
87.0 mm bore X 90.7 mm stroke contributes to increased torque band
Rigid aluminum (ladder-type) main bearing support, with cast-iron bearing inserts, enhances engine durability
Lightweight forged-aluminum pistons and heat-treated (carburized), forged-steel connecting rods add durability
Full-floating piston pins eliminate piston noise during warm-up
High-volume oil pump with silent chain drive
Compact, high-efficiency oil cooler
Cast-aluminum oil pan helps minimize engine noise and enhances oil cooling
11.1:1 compression ratio
Compact, DOHC VTEC cylinder head and valvetrain
Lightweight, MIM (Metal-Injection Molded), sintered-steel rocker arms
Low-friction roller-bearing cam-followers
Compact, 2-stage cam-drive with silent chain, scissors gears and fully automatic tensioner
Hollow camshafts function as lubrication path for VTEC valvetrain
Sequential, Multi-Point Programmed Fuel Injection (PGM-FI)
Intake system with straight inlet ports and low-back pressure exhaust system
Electric-motor-driven, multi-port secondary air-assist injection system helps lower hydrocarbon emissions
Meets California's stringent Low-Emission Vehicle (LEV) standard
Compact engine ancillary drive system uses a serpentine drive belt with automatic tensioner
Compact engine ancillaries, such as air-conditioning compressor and water pump, save weight and take up less space
Direct-ignition system with long-lasting platinum-tipped spark plugs
Low back pressure, metal-honeycomb catalytic converter

I cannot see how this is possible at all. Can you post a link to where Honda posted these specs? The aluminum in the pistons reacts with the aluminum in the walls and tears the **** out of the walls.
