There was an N/A RS at the East Coast Subaru Shootout (white with a black V5 front lip) and he was claiming 250 whp. We didn't get to see it run the Q-mile so we don't know if he was joshing us.

I think his website was www.excelleration.com or something. I have a sticker around here somewhere.

I know who you are talking about. I always thought he was more than a little optimistic.

Im getting dyno'd on monday hopefully, so we will see exactly how much i am putting down as well. I went on thursday, but the dyno broke and we never got a run. Ive never heard of anyone putting down 250 awhp N/A. It seems very optimistic to me, but I cant say for sure.

Either way, i dont know of anyone with the same mods as those on my motor such as 11:1 comp. pistons etc (id like to find someone and swap info though) and if there is someone, Im curious what they put down. Andreas put down 178 whp, and he had the fatsest N/A 1/4 mile of 14.36 i believe, I managed a shy 14.20 with no proper management (piggy back...but I have a link now). But that is what is goign to be tuned on monday and we will see what it can do.

Um, boost=FI...so that doesn't count. Im not sure if your're joking or not though! But any form of turbo/supercharger qualifies as forced induction, and not N/A.

JC-
Yeah, but with my luck, nothing ever goes as planned, ever! I told my friends that something will go wrong at the dyno because nothing goes right, and sure enough, the dyno crapped out, and if we kept trying I would have been one of the first people to break a tranny doing a dyno run lol! it kept adding crazy amounts of resistance randonmly...ebough to stall the car at full throttle in 4th! It made horrible noises too.

Actually, The dealer replaced all my wheel lugs and studs without a hitch today, so that was a first!

The new dyno appointment is set in stone for this monday at 7:45am! They put a wrx on after I left and gave it a shot this morning and it worked perfectly, so they think it will be fine for me when i get there. Im so excited to really see how much the Link can be tuned and how it will affect the car's hp.

Dan
Ill finally have something on paper!

Have a Nice Day? Dcoty

Dan,

Good luck on your dyno runs. I don't have much faith in dynos anymore. The critics on here will talk about the gear you ran in, your altitude, the altitude correction, the heat, the humidity, the type of dyno it is, the amount of runs, etc. It never ends and I just have gotten tired of it. Very few people dispute back to back 1/4 mile runs.

I'm just saying if/when you get some beautiful numbers, let it sink in deeply before you post. A lot of folks will happily discredit your nice dyno run(s) with as much stuff as possible.

Kevin (Still watching the N/A beast)

100+hp/litre without serious compression and variable intake runners, valve timing, high revs - I think not

My brother and I have a TIG welder now and we ordered some sheet metal to make an intake manifold. We plan on making adjustable runners so we can find the optimum runner length by changinng their length while on a dyno.

I plan on backing up any numbers I put down with 1/4 mile runs for sure. I dont think my dyno numberds will count for as much as good constant 1/4 runs. But I will post my results for arguements ake, then some 1/4 numbers. But I just hope there are no more hitches..there have been a lot.

Definitely let us all know how things turn out, Dan. I'm sure you're 1000x more anxious than all of us - this has been a long time coming!

And if anyone turns up the correct link the site of the guy claiming 250whp, please post it - I'd love to see that one!

w00t I found it. It took me a while, but it was REALLY pissing me off that I couldn't remember it. He added mods since I saw it last.

It may sound nice, but I concur with JC's initial assessment - the guy is waaaay optimistic if he thinks he's making 250hp. (It is worth noting that he claims 250hp, not 250whp).

The overbore only increases displacement from 2457cc to 2507cc, so that's not doin' much for him.

I love the "custom pod intake", which I'm pretty sure is just a 2.2L intake tube - BrysImpreza had that on his car and suggested I try one.

"Blueprinted" heads? What the hell are "blueprinted" heads? That means nothing. I'm assuming he means they are ported and polished. Porting and polishing ain't gonna get you to 250hp, though, without lots of other work.

11.5:1 compression and 250hp with no mention of any sort of aftermarket engine control? Not bloody likely!

Hello Pat,

On an extra note, the guy didn't claim 250hp. He claims OVER 250hp.

I dont think that car has 250 hp, no way. Thos mods just dont add up. Plus, that rear wing is hideous.

I'm with the nay-sayers on this one...no way 250hp. His intake pulls from the engine without a heatshield among the other things already mentioned. With that compression, can he actually run pump gas? and without engine management?

BTW,IMO
Dan's going the right route regarding playing with the intake runners to try and max out an EJ25 NA. I am building an NA engine in the spring and both Cobb and TWE have told me that manifold is the bottleneck to a serious NA build. Irish Mike's car (which TWE worked on) runs the new '04 manifold and TWE is supposed to flow test it after the season ends. Also, they told me it was close to 300hp at the crank on race gas...I am not in a position to confirm or deny their claim.

I heard the car last week....It sounds nothing like that anymore. It's sound wayyyyyyyy tingy and ricey-er now. That clip must've been with his borla headers and not his TWE headers.


We never had a chance to run the Q-mile, we were rained out. I drove 600 miles to get rained out. At least the drive back was nice...Can you say "Canyon Carving?"

Anyway, funny story; he raffled off one of his short shifters (his product) and ended up winning it back through the raffle drawing. All I won was a lousy Mach V T-shirt...I wanted the Turbo XS boost controller or the SOA WRX Service manuals.

I would think that if your spinning to 8,000RPM or so the stock tall and torquey manifold would not be the best. there hasnt been much as far as i seen concerning inlet manifolds. All the short runner manifolds ive seen are for aircraft where cowl clearance is an issue, and honestly I think theyde be better off running a stock manifold if they could only fit it under the cowl because the engine speed they run at is normally around 4,000 RPM max. Anyone ever try one of of those short sheet metal manifolds on their car?? the ones that come on EJ25 aircraft conversion kits? Eggenfellneraircraft.com is one of the ones i know ive seen with custom manifolds also another company thats uses SVX engines and EJ20s for aircraft purposes, forget the name though.
