finaly got the Ej20G wagon on the dyno


Recommended Posts

well i did it. took the wagon to KAS on their dyno day and put down some #'s. lots of people were not happy with their #'s thought they should be a bit higher, but O-well. now that i have had it on a dyno i can say that i have more power than a 2006 WRX.

 

 

this is a shot of the board. this is a 2006 WRX, i did not see it run so i dont know if it was stock or not. 180.2HP

here we have a 2002 WRX, again i did not see it run but was told by more than one person that the owner clamed to be running Stage II COBB kit 194.7HP

and my numbers came back at:

201.8HP @ 6043RPM

204.2TQ @ 4885RPM

here is my chart: you can see by the AFR #'s that my IC was a bit heat soked. time for a front mount...

i was the only non STI subaru to put down more than 200HP, not by much but i did do it, and that was my goal.

HOLY COW!!! Good Job man! That is so awesome! I bet there were alot of ticked off people after that run!:D Congrats on the good numbers!

 

The other WRXs were most likely bone stock, or close to it. Sport Compact Car dynoed a stock WRX a few years back and it came back with 189WHP and 199lb-ft. of torque. The '06 WRXs only come with 3 more horsepower at the crank in the turbo EJ25 engine(230HP) than the previous EJ20T(227HP). So those numbers are right on par with a stock WRX. If they did have any aftermarket offerings attached, then they must have had a really lousy tune on their vehicles, especially the guy who had the Cobb stage II kit. Those numbers should have been in the 220-230HP range with that installed. But who knows though!

 

Anyway, Congratulations again!!!!:clap:

w00t:clap:

 

big ups to dave on being one of the few at the dyno shop who wasnt disappointed... if you ask me that board should have had a spot next to HP #s for what the owners "thought" it would be... :lol:

 

what do they do as far as air flow over the front of the car for the dynotesting?? because air flowing into the hood for the top mount would probaly eliminate the need for moving it to the front, and if you put it in front of the rad thats just THAT much more strain placed on your cooling system.. whereas the topmount lets you run air flow (heated by the IC but its still air flow) directly over the back half of the engine.. isnt the turbo back in that region somewhere? (i ask because im ignorant, no turbo soobs in my driveway)

 

I forget who it was, but someone here on the board made a "scoop" on their wagon's hood for the IC that was essentially a small hole cut in the hood, and then the hood itself was bent down slightyly to provice a ramp going down into the engine bay.... it looked good, no snorkel or anything. from the back side of the hole on back, it was a stock hood..

 

anyhow, congrats again, now that you have knowledge, its time to go pushing around for 210, 215. right?

Ummmm, I'm really not trying to be rude, but the reason why they would place a fan in front of the car is to create airflow conditions that would normally be found when the car would be moving at that speed(because the car is tied down on the dyno instead of moving forward like it would be when driving). You have to keep the engine temps consistant to get consistant numbers. If you were to run a car on a dyno and not have sufficient airflow over the radiator, you'd get lower numbers and perhaps run the risk of detonating because the engine can't get rid of the heat properly.

 

Also, if you check out his webpage, he has a scoop on his hood to feed cold air over the intercooler(it is the wagon on the left side of the pic), so he is good in that department.

this thread interested me . I went for a web search and lo and behold, I found another swap, to an ej20 from 2001. It looked like suberdave's car colors, it turned out to be another swapper.

112kw == 150 hp, it was acheived at 7200 rpm. Suberdave's is more powerful.

above link is dyno chart

below link is if your interested in the car:

The conversion site is useful too (kw to hp, etc.):

http://www.statman.info/conversions/power.html

 

Does your ej20 have extras? The power difference is huge to the one I found. Including the rpms to acheive what you did.

i have done a few small things like new up pipe, 3" bellmouth Downpipe, and full 3" exhaust, no cats. i have installed a TurboXS MBC ay stock boost. O-Yeah i also have a huge tach. and thats about it... and i dont know if it makes a differance but i have 4.111:1 trany insted of their 3.9:1 trany.

 

according to this sight http://www.catherineandken.co.uk/sti my car is a V-limited WRX. (EJ20G with the same trany # as the 555 car and V2 STI.) now what dose that mean? i have no idea. but maybe i have a little more HP. or maybe the engine on www.funonwheels.net was from a WRX wagon witch only had 240HP insted of 260 or 275.

not to be rude, but...

 

I saw no fan in the photos, and was wondering on that point, hence my question, "what do they do as far as airflow on the front of the car when dynotesting?"

 

thank you for clearing that up :grin:

 

and after your comment about him already having a hoodscoop, i looked back at the photos posted in the thread and realized that the only head on view was from such a low angle that any hood scoop would be obscured.. I guess i failed to notice one and assumed there was none, oops. :rolleyes:

It also stated the 555 v version had water injection. Blue printed engine to stronger tolerance (cosworth crankshaft?). No matter what other version your car has some nice numbers. Its the limited edition "The Suberdave" :lol: .

After finding the Cosworth crankshaft.. I almost became a fan of the crazy 5 bearings.

seeing 3500 dollars for something subaru should be doing is sickening.:mad:

you can consider this information verified....that's my friends car...he's got some "issues" around 5k rpm

 

anyways, congrats! not to mention the fact that you have about 1000lbs on them anyways!!! I was going to go to see if I could break 100 with my stock 88 GL-10, but opted for the rallyX instead :D
