Just got my new site up with some dyno vids, pics, etc, and I thought the prelude community should hear a true turbo prelude on the dyno.

Here is a link for a 486whp run (on a mustang dyno) done @ 22-24psi.

good number , What is the size and cr of your pistons???

 

NICE! I remember XES from the HondaPrelude.com days...we would always have to link to your setup.

Are these numbers adjusted for elevation? I seem to remember the air being lense dense up there.

 

Neato.. I've seen you around town.

 

Very Nice.....weren't you selling your car a while back??

24PSI... Wow!! now that's boooooooost!

 

The dyno numbers are altitude adjusted, but the runs did take place on a Mustang Dyno. Typically Mustang dynos yield values 8-12% lower than a DynoJet.
The expected whp & torque values are as follows:
530.5 - 550.1 whp & 433.5 - 449.6 ft-lbs torque

Given a 15% loss from the engine to the wheels, expected flywheel values are:
610.1 - 632.6 hp & 498.5 - 517.0 ft-lbs torque

 

all i can say is "WOW"

my little h23 has that much potential eh...too bad i don't make enough money with my job

 

got damn, those numbers are insane...theres a guy in the accord forum with a boosted h23 in his 5g accord, i think he's boosting around 300whp give or take a few... he would be happy to see these numbers..good job

 

those enkei katanas are HEAVY i had those, if you get some te37s, can improve alot

 

OMG!..im giving u most props man thats is the sweeetest thing hearing the guy say HOLY FU*K 486! lol nice nice ....i love to see a lude with power from hell

 

 

"Holy Fawk" lol

486hp - sounds like a V8 crusher to me... and maybe even more...

 

 

Holy Moly!!!! WOW!!!! I envy you...you are my new god!!!!! hehe...nice setup man

 

Piston size is 88mm, while cr is lower than stock...(i.e. lower than 9.8:1, but not in the 8:1 range). The pistons were custom made by JE last year after I went through 2 shitty sets of Arias pistons. I highly recommend <U>not</U> using Arias -quality and customer service are weak. Anyways...why run anything other than what the pro's (NHRA imports) are using?

 

YES XES I KNEW IT COULD BE DONE!...saweet...you are an inspiration to all h23 owners out there....excellent job!

 

Nice work and a local too!! Haha, I think I got an email a whiles back from a buddy on the turbo you have in your car just before you bought it, its the size of my head.....newayzz

 

how much were your sleeves and rods?

 

wow, awesome. and on a mustang dyno.

i thought my 450whp at 18psi on my old ls/vtec was impressive.

very nice. it's good to see a big dog prelude instead of so many integras and civics like mine.

very nice numbers.

 

Ok you are saying he ran a 12.3 @ 118 ? His time slip says 12.4 @ 112 with a 1.8 60 ft. I can run a 13.8 @ 110 mph with 12 psi and still keep hitting 2.6 60ft .His times should be alot lower than that. How much psi did he run then? But then again I only put down 386 whp at 20 psi. But really nice setup though. I was just curious about the times there.

 

Holy mother of Boost

 

he's at 3700ft elevation.

cars have different traction problems at the track. though he put down 500+whp, it's tough to tame on the track.

my 99 gsr spun it's slicks on the track. and they were 24.5 inch slicks.

 

Very impressive setup! Props
Sounds like you'll run some sick times with slicks and a limited slip.....either that or break axles like crazy
Brian

 

awesome car man. That is some good power u are making.

Could u give us some of the turbo specs. Are u running a t3 turbine housing? what a/r raio are u runiing..etc.

Its cool if don't want to say anything and keep it a secrect.
