Finally after almost 4 years

[Reffoxel]

Well, finally after 4 years from the start of the project my car is almost done. Due to various delays of one sort or another, the only thing left is to have the front bumper mask fitted and painted. Last night the tuner (very close buddy of mine) finished the initial tuning of my car. I say initial because after I get use to the car as it is now we will be turning up the boost as far as pump gas will take it then on to race gas. The engine is build with forged internals, compression upped to 9.7:1, port and polish of the head, upgraded valve springs, Modified Edlebrock intake manifold, 75mm Mustang throttle body,HKS foam airfilter, Acura RSX COP, AEM EMS 1050.

So here is my dyno sheet.
The solid lines are on 93 octane @ 12.7 psi of boost 332 hp 273 ft/lbs
The dotted lines are 93 octane @ 10.5 psi of boost. 291 hp 247 ft/lbs

We set redline at 7500 rpm but as you can see hp was still climbing. We just ran out of time on the dyno to explore any further.

What size turbocharger? Great #'s BTW

 

[funktownp5]

Oh also, how far you revving it to?

 

[S.A.MSP]

can we see pics of the car? engine bay pics too, i need to see the Intake mani setup!!

Excellent #'s!!

 

[daonly1around]

yes, more details and pics please...

Neat stuff. Keepin an eye out for a yeller p5 now.

What was the reasoning for upping compression to 9.7?

I was under the impression that NA guys go for high compression, high rev power.,

Turbo applications trending more to lower compression with higher boost.

Perhaps my view is too simplistic.

ps congrats. Sounds like a fun ride!

Well generally that's true. But the lower compression with turbo rule came out in the 70's and 80's before the use of intercoolers and descent engine management. Higher compression means more efficient combustion. Which means you don't really have to run as much boost or as much timing.
Course my numbers aren't just due to slightly higher compression, but also because I'm running a GTK650 pushes alot of cfm. Also my intercooler is as large as the radiator. My charge temps were around 107F on the dyno w/ no direct fans blowing (dyno was setup mainly for rwd cars) and my engine temps never went over 165F (those AWR performance radiators are amazing).

I'm gonna pick up the car tomorrow and take it home. Will take pics and post them up.

Awesome stuff for such low PSI...expect to retard that timing a lot after you start uping the boost more. Looking forward to the engine bay shots.

 

[Reffoxel]

Here's a couple of engine bay shots.

Picked the car up today. before I trailered it home, I ran it up and down the street. DAMN! I've never actually driven a turbo car.....when the boost kicked in ........ well all I can say is WOOO HOOOO (headbang)
Kinda scared to drive it on the street, cause I'm scared I'll get busted by cops.

uh.sub..more pics?

Ok these questions need to be answered ASAP...

-What ignition coils are those
-where did you get that intake manifold

 

[S.A.MSP]

we need answers stat!!!!

 

[xDJ DUBx]

Damn!

subbin 4 sho

 

[speed3guy]

I dont really care about the intake mani... Im more concerned with what kind of exhaust mani that is!! That thing is awesome looking!!

 

[slomsprotege]

you should really list your mods, i got rid of my mazdaspeed protege because i thought no one was making any real numbers, then a week later i see this post thanks for being a minute late @#$hole, jk jk, but no really, what parts you put on that thing, its an awesome and good build from what i see especially the fuel rail that you could push a goat through

 

[StealthWyvern]

Subbin for more info.. Setup looks a lot like brainM_MP5T(I think that was his screen name)

 

[LASERBLUE135]

That's a crazy build...what TRANSMISSION work was done to handle that power?

 

[Reffoxel]

The ignition coils are RSX COP (coil on plugs)

The intake manifold is a Edelbrock Victory Jr for an Acura Integra, we had one at the house along with an extra OEM manifold and noticed the runners lined up. So cut the flange off both and welded the OEM flange onto the Edelbrock also fabricated a flange for the mustang throttle body.

As for the Exhaust manifold, yes it is generally similar to Brians but only generally. The pipes are routed differently, the turbo is mounted differently. While I can't really see what kind of tubing his is made from mine is made from Schedule 40 Stainless steel. It's seriously strong. we actually lifted the engine out of the car with it (had to send the engine back to the machine shop cause they screwed up and hadn't notched the piston skirts for the oil squirters.)

As for the transmission well, nothing as of yet. but I'm seriously looking at getting the PAC gear set if they are still available. Otherwise my buddy was thinking we might be able to make an adapter plate to fit an RSX transmission. I do have the Driveshaft shop stage 2 axles.

But I also have the TurboXS multistage boost controller so will atleast be able to bring the boost on in stages so as not to shock the tranny as bad. Also as a stop gap measure I know where I can get a gtx tranny for cheap.

Awesome man...I would think with that manifold you would lose a lot of low end power but maybe your pistons are making up for the difference. Why go with RSX plugs if the stockers work fine? 1000cc Injectors for what too? How is your idle and what engine management are you using to control it. Lastly if your friend CAN make you an adapter plate you can DEF count me in for a second one though how would the gearing work out on our cars. Would this be the SI 6 speed of the RSX 5speed tranny?
