No not yet... stupidly expensive project cars kind of dried up in the NA forums about a year ago... the thread is full of great ideas, but very little in the way of substance (something I'm personally guilty of, but bought a house/got a decent job/don't have time)

Well, my build continues - although it looks like it will be a slow process given the same issues with lack of time and money.

I doubt I will get to the 200 hp at the wheels but I will try and wring the most out of the engine with what I have :)
 
For me half the fun is trying. I too have a son on the way (due any day now!!) so available time and money has decreased but I can still try. Running through the some of the equations reminds me of much fun physics used to be.

I am in the same boat..between work and my new (bought in May) house I find the time to be at a premium to work on the car, and the funds as well..I am still making progress, hopefully in the next week or so I can get my car legal, then tuned and dyno'd. Once that is done, the ITB setup can go on and I can get some new numbers for the ITBs on a stock internal DE..I just bought new H-beams, to replace the I-beams that I have..so hopefully shortly I can get the block to the shop so they can get started on it..
 
That is either Leo or the PRM car.

Leo on his last dyno was ~26x whp. His motor was using stock ZE heads, with a built HLA valvetrain..but his bottom end was not a stock ZE bottom end, it was 11:1 pistons with SBF SCAT I-beam rods, with shaved heads to create 12-13:1 compression..
 
It has been done..not in a street car, nor by someone that is an active member on here...yes..or pretty darn close to it anyway. I dunno the overbore on his engine, but a .020" over bore on a std. KL is only a 2.54l or so..

On an engine dyno, not a car dyno, and it never ran on the street with the tune it used to get those numbers...
 
I cannot say for sure if the dyno numbers where engine or wheel hp..I have a hard time believing he took the engine out all of the time to dyno it...I could call him if I really cared that much..I was also under the impression that him didn't really drive it on the street hardly ever, and the way the HLAs deflate after a WOT pull, I doubt he did much racing at all outside of the track..
 
We know the KL has made the numbers before, but as per the rules of the race,

#3 - MUST be dyno proven. A photo must be posted of the car on the dyno, a photo of the dyno sheet must be taken on the bonnet of said car, and a scan of the dyno print must be also submitted. Power to be measured AT THE WHEELS.

#4 - To stop any diddling of results, you must also include a handwritten piece of paper with your name, "Mazdas247.com NA Tech Race To 200whp" and the date on every image submitted... I may also ask for proof you are not boosted, not running nitrous, and not running a water or water/meth or meth kit on the car.

...

#7 - RULE ADDITION..... all people competing in this contest must start a build thread, detailing what they have done. Pics or die . Once we've got a few, i'll set up a consoldated sticky as a directory to everyone's builds.

#7a - Rule Clarification - competitor must be an active member of the forums to be considered victorious. Whilst there may be examples on other forums of people achieving this goal on our engines, the intent here is to encourage wild NA builds within our own ranks, and to expand the community's knowledge when it comes to extracting big power out of small engines.

So achieving it on another forum, without a build thread, questions on whether power was measured at the wheels or the engine etc.... not a winner here. The point is to build one on this forum. Not someone elses forum.

edit: there is no requirement that the car be a streeter. In fact its unlikely that certain engine choices could be used on the street (an FSDE pushed to the limits would be thoroughly horrible to drive on the road for example)
 
True...all I knew is it had to be an active member here, since we had gone through this before ;).
 
I don't think really anyone else is going to break 100whp/L and be an active member with a build thread
but it is very possible to achieve it, if you have the money laying around
 
I fully intended to be well clear of 250whp on my KL build..I don't see an issue of doing it either, provided it all goes together as I am hoping and I have done my homework..
 
I applaud the guys that are trying. I still miss my MP3 and I pop back in here from time to time to see whats shaking. The rules you guys have set up are pretty lofty goals for any engine and I totally respect the effort. Even with my current 5665cc LS1 id have a hard time hitting 100whp per 1000cc without boost. Most of the really radical head and cam cars only hit the mid 400's.

that speaks more for how terrible the LS1 is...

100hp/cc NA is doable on an efficient engine.
 
Nice to see there is still some activity on this thread. My ~150whp protege is still running well. Never did get around to really trying to optimize what I have. I keep thanking the man upstairs that the car still runs after everything I did to it in college...
 
Hmm. Did 190whp on my 2044cc B series block without touching the head- might have to try and build the wife's 5. :)
