I dyno'd my car a while back and I got 235 wheel HP and 262 engine HP @ 6300 RPM's. I was wondering if thats good for auto? I was told it was. Any other auto V1 or V2 SC'ed Max's with anything like that and if so do you have more of less HP?

p.s. I have a 3.25" pulley on my V2

yes thats way off... add it up... engine hp... stock is 190 .. that means from all your mods, you gained 72hp from them combined... it just doesnt seem right :/

 

I only did 2 runs cause my SC belt wasnt tight enough and slipped off the SC puley. I had it fixed but I am gonna dyno my car again next month and see what happens....

 

I think that's about right..

 

numbers sound kind of low.... I think you need to tune it...

just curious.... how did you measure engine hp?

 

For that small of a pulley you running you should have picked up a lot more HP since your running like 11-12 psi boost...

Pop on a Mevi and you can add 30hp to that

 

i thought it was 9-10 lbs boost for the 3.25 on a v2.. jamie sorta kinda convinced me that those numbers are about normal =/...

 

I dynoed at 244HP with the 3.25 pulley at 5.9PSI, slipping belt.

there is the dyno chart if you want to look at it. Thats HP to the ground.

Is this SAE corrected?

What was the smoothing factor on the dyno plot?

How did you determine drive train loss to calculate engine HP?

 

Thats not great but not to far off...The stock auto puts down about 174...190 is the manny... You gotta boost gauge? How much do you hit top end. Most autos put down about 245 so 235 is so so.

 

For a 5th gen yes, but he has a 4th gen. #s to the ground going to be lower.

 

I am going to post the dyno results as son as I scan them. I dont know ecactly how they determined those #'s but they did hook a wire onto one of the FI'ers I believe but I wasnt sure. I was just ****ed about the belt slipping off and didnt pay much attention to the rest

 

What numbers should I expect for a 5thgen auto running stock pulley?

All performance mods included..

 

How many psi of boost where you running when you dyno'd, cause that helps us know if the numbers are low or not. Like if you're running 5 lbs boost on the 3.25 pulley, then you have a boost leak and that'll give the lower numbers.

Also, what torque readings did you get from the dyno?

 

Sorry Guess I missed what gen it was.

Stock 5thgen at top end will make 6psi dont' be to upset if you only get 5 psi though, figure around 240-245 hp. 220 ft/lbs tq.

Now that I went back and read it again and see you have the 3.25 pulley that is really really bad. You should get at least 9 psi 10 psi top end making around 280 ish hp, at least. When I tested my 3.25 pulley without the intercooler I got 9 psi at 6300 rpms and made 290 ponnies.

 

Yeah, I'd like to know how many psi he's running with that 3.25" pulley.

 

The belt was loose plus I wasnt in the car when it was being dyno'd so I am not sure how much PSI i was running.

 

What's with people dynoing with loose belts? Sounds like you're not getting an accurate measurement. I want my car to be in perfect readiness when I dyno for the first time.

Could you ask the shop where you got dyno'd what PSI your car was running? If it was a while back, I doubt they'd know, but maybe they have it in their file for your run.

 

Makes me wonder how many ponies im making... I dont have exhaust yet or the Cold air for the blower yet though. I am getting 5-7 psi anywhere around 3500-like 4800ish rpms. I dont get to 9 or 10 psi till almost redline. I have not punched my maxima from a stop yet, only when it is in gear going like 25ish, still breaks the tires loose...

 

What's the deal with loose belts?... I just used the belt tensioner... and I hit 9 psi, guage looks like it hits more like 9.5, it could just be my eyes.... oh and I tried topping out the car on a closed street with no traffic of course, 10 lbs boost really does help on the top end, thats all i hav eto say

 

I didnt want to over tigten the belt so I was scared to tighten it up all the way. As far as the shop knowing what PSI he was pushing they would have to disconnect the vacum and connect it to their vacum straight to the computer to get an accurate reading, thats how I knew what PSI I was pushing on a slipping belt.

 

That's cool, just wondering if you got a boost gauge reading when you were dynoing. I'll be going for my first dyno soon and I'd like to know what to look for and check while my car gets dynoed.

Thanks,

 

make sure your wheels are top dead center not behind the round wheel like my wheels are placed above just clik on the link above to see what I am talking about. and make sure your belt is tight so you can go out and boost and see if your gettting full boost and thats about it.

 

I Dynoed at 238 without the MEVI with a 4th Gen V1 and 3.25" Pulley. This was before I had any exhaust except a Y-Pipe, however.

I gained +10hp with an exhaust, and +19tq!

With the MEVI, I'm at 277hp at the wheel, and 243.3tq (with exhaust also)

I think you're a little low, but not a whole lot.....maybe 5-10hp.

i hit 8PSI on my gauge, BTW. (About right, I think, because V1's boost about 1PSI less than V2's)

Before and after MEVI - although the red run was not my best run that day (like I said, best run was 238) - but it should give you some ideas.
