a member of the swedish nissan 200sx club www.200sx.nu (http://www.200sx.nu)
has dynoed his 14 blacktop to 765 horsepower at the flywheel with vp csp fuel, and 628.5hp with pumpgas

he's got a website, but its in swedish: www.madtech.se (http://www.madtech.se)
heres a video from the dyno:

Sweet. Thats a lot of power, even at the flywheel.

Do we know what has been done to the motor internally? What turbo setup?

Wow, 1600cc primary injectors? How the heck do they run this car at low RPM? I'm impressed. It's not easy to idle on an injector that big.

My boss' car, a 2.3l mr2, is running the Siemans 160lb/hr (1680CC/min) injectors on his car, using the same Autronic standalone, and we were idling the car at 900ish rpm with a solid 14:1 AFR. The Autronic systems are well known for their ability to control large injectors on small engines http://forums.freshalloy.com/images/graemlins/smile.gif It wasn't as hard as I thought it was going to be, only took me about 5 minutes to get it idling like a champ.

He was being sarcastic. There's a lot of people on this forum who feel those parts are junk and wouldn't hold up in a powerful motor.

Proof positive.

The problem that people had with the Clevites was not the bearings themselves, but that they only came in 2 sizes.

Hi,

I have found this thread by our homepage stats. If there is anything that you guys want to know, just ask and I will try to take the time and answere.

I also have a question for you, who manufacters bearings for the sr20 engines? We went with the clevite bearings but they have a hole in it, and thatīs no good for the oilfilm. Any suggestions can be e-mailed to: info@madtech.se

the Main (crank) Bearings need the holes so that the crank can get oiled.

the rod bearings have a hole for the factory rods. the factory rods have an oil squirter hole in the rod that helps get oil to the wrist pin. aftermarket rods do not have that oiling hole However, i have never seen an SR20 rod bearing that doesnt have the oiling hole.

nice setup.

Exactly what I ment but I didnīt have the words for it... that oilhole ment for the factory rods lowers the oilfilm lambda value to almost halv the strenght it would have if it had not been there!

So, no sugestions are most welcome.

The head has been through a big development, we sacrifised a head for testing different port design, and put the best port on a new head. Tested things such as port design vs port area, also tested different valve seats.

Man, boost at 6k to 8500, that must be a wild ride when it gets up there. Nice to have the 8500 red I guess thanks to the mechanical valvetrain?

Would you care to share your findings? You don't have to give specific detail since obviously this was on your dime, but a general analysis would be greatly appreciated. http://forums.freshalloy.com/images/graemlins/smile.gif I noticed you kept the stock valves so the increased flow from oversized valves was deemed unnecessary?

MADTECH
05-31-2004, 09:23 AM
One of our goals was to be able to use the stock valves, and to show that bigger valves was not needed, I have personally never seen any sr20 without stroker-kits in theese hp range. We mapped the engine using BMEP as a pointmark for a straight torqueline, if you look at the dynopics you can see that the torque is flat with pumpgas (95 RON+MON/2) but with VP Racefuel the turbo could not hold up the boost at the higher revs so the torque drops. I know theoretlicly what kind of figures the engine would produce if using a bigger turbo, but we alredy have enough power so it wont be needed in a near future.

The porttesting gave us a lot of interesting results, and I dont mind telling a bit general about it. Letīs start by saying that the [censored] know what they are doing, and just grind up a port bigger perhapse shows a better result in a flowbench, but a bigger port also slows down the gas velocity. The swedish engine guru "Dr. Ernie" help us with this development and we did our own camshafts, and by not telling to much, I can reveal that the lift are not anyway near the "high power" cams such as JUN and so on... our camshafts has a lift of 10,8mm compare that to the JUN:s and probably many of you would get some headace.

Here we are running just regular pumpgas, using about 600hp.

for some reason id be afraid to be in the vacinity whent hat trans finally gives up. ive seen some carnage from a RX7s transmission blowing up, sending metal through the floor and firewall.

holy crap that car in nuts. must be a surprise to supra guys http://forums.freshalloy.com/images/graemlins/laugh.gif

im assuming the car has a misfiring system?

MADTECH

We are now running a BMW M3 transmission, because the stock broke at the strip.

And we also made a special plate protecting the tranny and flywheel made in 6mm steel, incase it would blow up.
