Mine just got dyno'd at 215 whp stock, so 255whp with just a DP seems pretty insane to me as well.

 

And that's exactly why you can't make the assumption that the cobalt will destroy the z like all of the nuthuggers want to. . . you just reiterated my point. If it is an 07+ z, it will at the very least keep up with the ss.

 

still have yet to lose to a 350z and i have raced quite a few modded ones. oh and im just a ss/sc

 

370 Z's can't even break 14's around where I live without FI. Then again the track is at 3200ft.

I love how people say that a "stock" 350Z ran a 13.1 at 109..... its not capable of it. The 370 Stock only traps 108 on a very very good day at sea level.

Also how many people that go to the track, track a stock car.

 

Sorry guys at work, but I believe his car is an 05. I don't think its that HR nonsense bud damn this thread blewe up reall quick lol but thanks for all the info.

 

There's a thread about Cobalts vs 350's every 4 days. lol

 

whats dude name lol

 

That's what I was thinking. Didn't want to ask honestly thought I was going 2 get a bunch of hate posts but oh well. But abouty my homeboy talking **** he was doing it today lol.

 

Elias is his name u know him or what lol

 

My 350Z ran 13.47 @ 103.8mph with a DA of 1800ft and its stock. A friend of mine ran his stock 07 350Z his went 13.29 @ 106 at the same track with better weather. HR 350's are more than capable of low 13's. However like any other NA car they are severely affected by the weather. 370Z's aren't that much faster than HR 350's believe it or not.

 

i was wondering that about the hr vs 3.7... i love my little hr

 

I think you're insane for not asking for a refund. Talk about a heartbreak dyno

OP, I say race him. I think he will win, but not by much. His ego should come back to earth a bit.

 

Well then I'd go to a diff. dyno cause that seems rediculously low

I didn't know they went lower then a mustang

FYI I got dynoed on a dynojet so the number may read a bit high or whatever you wanna say but 215 is not right

Your not losing that much hp from a FWD car

 

Fast Nissan 350Zs 1/4 Mile 0-60 Drag Racing - DragTimes.com

fastest 350Z non HR with just intake and exhaust and NO tune ran a 105 mph trap with the majority being in the 102-103 mph it will be a good race. most stock ones seem to run around 100 mph with alot in the double digits its all right there.

He has around 20-30 more hp than you and you are 250 pounds lighter than him at the end of the day it will be a good ROLL race and it will come down to who shifts better.

I know the results of this race from personel expierience but that don't mean much on a car forum. Spend the 300 bucks get yourself a tune but don't tell anyone, race him and put 6 cars on him then go back and tell him all you have is a downpipe he will look at you like you just slapped his mom.

and yes there are 109 mph stock HR's on that site so stop arguing about it

Those are the hard facts. no nut hugging. end thread.

 

im referring to actual alt, not calc DA. The calc DA around here is usually 4K+ ft. I can see a 13.29@106 (With better weather the DA may have been at close to 1K) But a 13.1@109 seems like a bit of a stretch for stock.

 

The biggest problem with the old 350z's is that they were designed by a california beach bum who thought making the car weigh a billion pounds would be a good idea. If the 350z owner did a lot of weight reduction, id put my money on the Z vs stock cobalt ss/tc.

 

It's a dynomite dyno and from what I've read it may not give you the big numbers people want to see but it is by and far the best dyno to tune on. So I do plan on going back as I start modding. I've only put 2500 miles on her as well so we figured that there is still a little more break-in that needs to be done on the drivetrain etc. which would probably put me around low 220's which is pretty typical for a dynomite/mustang dyno.

 

somebody go on a z forum and find an HR to race.

 

They fudged the results. No way a completely stock stock TC is going to gain 15 whp from a DP. MAYBE on the first pull before the PCM can adjust the DAL, but I guarantee after a few pulls the best you are going to see is a 5 whp gain. The only way you can really increase power on a SS/TC is with a tune.

 

I'm not gonna argue

Simply what I'm saying is that "Synapse" gained 15whp with bolting on a DP

If you don't beliveve me then fine lol take it up with Synapse if you have a problem with that

 

Actual altitude doesn't mean jack if the air density is the same as being on a mountain. I raced at Gainesville Raceway all the time. Actual altitude there is 160'. DA is always several hundred feet if not a few thousand. I've been out there before and only be able to run 14.0's at 100mph because the DA was so bad.

 

My MS3 w/intake dynoed at 228 on a Dyno Dynamics. so its very possible a stock Cobalt SS may dyno for around 215. remember a Dyno is a tuning tool, they are not made for braggin rights like most people think


the same MS3, bone stock made 236whp on a dynojet

doesnt the SS's ECU adjust for mods? if so i bet if you dyno the car a month after the DP install, it will dyno very close to stock

 

Actualt alt does mean jack when you are going away from sea level. (up) Theres no good da when you get above 2500 ft.
In actual.

 

So just because you live up high you are saying that other peoples cars that don't can't run a 13.1 @ 109?

 

The OP lives in an area where Altitude is 500ft so if the weather is right, a 13.1 out of an HR is a possibility.
