It wouldn't matter either way! The car will show gains on a Mustang no different then it showing gains on a Dynopack.

The shop that had the Dynopack didn't do as I asked! So to me that is shaddy. They didn't do a base pull before the bolt-ons. Didn't install a wideband! Didn't state how many pulls or what temps/humidity was!

I nolonger do business there! So to me they are not credible...... I would be open to going to a professional shop with a Dynopack to see what they have for results.

But as for the shop that claims to have done a dyno I have to wonder.... I never even saw a print out. So everyone would have to agree thats Bogus!

 

So, find a Dynojet and run your car and report back. Till then your overly high numbers are ignored.

 

......it is clearly apparent that this dyno is considerable over-corrected.

 

Next time the car will be on the Dyno will most likely be after I get the Zex kit installed. Program another tune

I need to get a Quote from performance Nissan of L.I for Cam install. They are pretty booked right now boosting a couple Z's. Doesn't help that the one shop I trust is 4 hrs with traffic The car would be alot farther along if that wasn't the case.

 

you're getting cams? GTM? they're the only ones that i know of that make cams for the hr...

There is also Kelford!

^^ In all sincerity, i don't think you would break 265whp here in the Mile High City. Even if the "altitude" factor is put aside, your at 295whp at best Lakeside on a "fair dyno" at regular altitude. I'm not trying to start beef with you, (i'm a vegetarian) lol

As for cams and spray, i wish you the best of luck. If i had the engine open, i would make one difference. I would go with the GTM 302 cams, with spring and retairners etc, CP Pistons, Eagle Rods, your prefered choice of timing, and that 100 shot of juice.
Might as well go ***** out, right? That's if money ain't a problem bro...

 

Dude how many times do you need to tell me that? There's an entire 7 or 8 page thread about it and half the posts are you bitching about any HR with numbers higher than yours. We all get it, your car is the end all be all HR and any other car putting out better numbers is obviously on a fantasy dyno. I'm sure the OP was looking for worthwhile mods for his car by seeing what other members have experience with, not to start a horsepower pissing contest.

 

Laugh. Actually I was part of that conversation, but not the main people saying that. Mine is a one of the only legit dynos of a HR with almost full bolt ons.

 

^you still have stock headers, right?

 

How do you figure? There are several HR's with full bolt-ons! Mine included. The only thing I have not installed is my Injen intakes. Why? Personally I am satisfied with my stock air boxs. Your also in Texas! Climate is vastly differant when comparing Humidity and air temps to Upstate NY.

 

i agree maybe on dyno pack u can make 300 plus wrhp

 

Yep, and headers on the HR are a waste.

 

Dynojets take into account this.

 

um mustang dynos read lower numbers and dynopacks read higher numbers the closest u can get to your real whp is a dynojet but they can be wrong to i just bought a 09 cls63 amg they say on dynojet it should be around 410 to 420 rwhp but it was more like 403wrhp . its albout the condtions like for me it was to hot temp was 93 degrees

 

Generally speaking dynapacks read higher than mustangs...........of course putting a wild correction into the mustang dyno (and vice versa) can swing that. Bottom line is that dyno needs to be recalibrated.

 

If you had aftermarket headers you wouldn't be saying that!

The stillen headers are far more equal in length then the stock HR headers with an increased tube diameter. I also took some time to file smooth the welds on the collector's and slightly enlarged and smoothed the exhuast ports on the headers. Whether or not this helped any?! lol Who knows! But I took a couple hours to perfect the quality of their product in my eyes.

 

everyone (very few) that's gotten headers on the hr so far saw gains with them. while peak power didn't go up much, there were good gains through out the rest of the rev range...

with headers and a cooler day, who knows, maybe you'd break 300 whp on a dynojet...
