HPTuners Dyno Tuning Results Motor and Nitrous

[Ninjazx71]

UPDATE: Video posted below...

So it's been a bit of a long road with getting my nitrous kit installed and then finally getting a chance to get it tuned. Well, the day finally came and I just picked the car up from the shop I had do the dyno tuning. All I gotta say is WOW!!!!! I couldn't be happier with the results and cannot wait to get this thing out to the track and try the spray out.

Mods: Gen5 Intake, Bellanger Headers and Cat'd Exhaust, Forged Pistons/Rods, ACR-X Push Rods, Nitrous Outlet Twin Plate Wet Kit (200 Shot), HPTuners, Tuned at StraightLine Performance in Joliet, IL.

Motor Only: 649 RWHP and 619 RWTQ!!!!
200-Shot: 802 RWHP and 843 RWTQ!!!!

AFR looks good around 12.7/12.8 on the motor and then about a point lower on the spray...

Wait, so this is stock heads and cam?

X2 I'd like to hear more specifics on the build as well.

Yes sir... this was MntBiker's old B&W one from down there in Katy, TX actually. The motor was rebuilt by Arrow a few years ago when trying to diagnose a problem that ultimately ended up just being a bad cam sensor. While the motor was being rebuilt Arrow installed their forged pistons, rods and ACR-X lifters. Other than that, it's stock heads and cam...

Stock displacement and compression as well?

Yes... I believe the pistons were +.005 IIRC...

Well the car definitely put that power down and congrats!

However, how can a basically stock Gen IV motor with intake and catted exhaust gain 120whp/100wtq without ported heads, bigger cam, more ci, or higher compression? Aren't most Gen IV heads/cam cars with bumped compression making 640-660whp?

EDIT: Please don't think that I'm doubting your car! I am just curious how you were able to achieve those numbers when I have seen what other Gen IV cars do with full bolt ons, ported heads, cam, and compression raised!

No worries at all, I was pretty friggin' surprised when I saw the numbers as well. That's why I had to post the graphs to back them up. I've seen some other full bolt-on cars putting down in the 620-630rwhp range with dyno tuning on HPT. Apparently HPT also opened up a few more options in their SW which may help a bit on the tuning side of the house. Some have said that for one reason or another, a rebuild by Arrow seemed to help out in the power as well. So could have just been a combination of a number of factors that all added to the final results, but unfortunately I don't have a solid answer...

You don't need a solid answer when you have solid results...it'll be even better if you get a chance to run it at the track in its current form.

Yeah, I had plans to go this Friday, but Mother Nature doesn't look to be cooperating at the moment... And getting late in the season, but I will somehow find a way to get there at least once. Plan on running it NA to see what I trap at on the new tune/numbers. Was trapping about 126.8mph on the Mopar ECU, but think there was a bit more in it if I shifted to 4th gear. Didn't get a chance again that time b/c the stock clutch wasn't too happy at that point.

Very nice, I think I have seen you a few times at the track. Your car runs pretty strong. Good luck next time out with the new combo?

Absolutely killer!! Congrats on the results.

I was about to say, have fun on those two runs on a stock bottom.

Otherwise, it all jives perfectly. Mine pulls 625hp with a good tune.

Bolt on with the right tune....

LOL! So true... if John hadn't gotten the forged internals on this engine I would have never tried pushing it like this. The shop was a bit disappointed with me since they wanted to bump it to a 250 shot but I didn't have the jets. HAHAHAHA!!

Even with the Nitrous tune in the car, with timing pulled for the spray, it still puts down North of 600rwhp which is more than I put down with my street tune last year when I dyno'd.

Congrats on the HUGE numbers! Are you positive that nobody added a more aggressive cam or ported the heads when the rebuild happened??? 649whp on pump gas on a Mustang Dyno is ridiculous! If you were on a DynoJet you probably would have put down around 725whp. Trust me I'm not saying I don't believe you, I'm just saying I think something else is done to that motor. At that power level you should easily slip into the 9's in the 1/4 if you have traction, and that's on motor...... I can't even imagine that thing on the giggle juice!

Thanks man... Confident this is stock heads and cam. I contacted Arrow about the build before I bought the car just to verify everything, and then even got the build sheet from them. Previous owner was meticulous about documentation and gave me a binder with every touch on the car whether an oil change, new tires, etc.

DriverMod will need some work to bring this thing anywhere near 9's I think. Shooting for low 10's and then will improve upon that with practice.

[Resident Alien]

Congrats Matt, awesome numbers!!

[ACRucrazy]

Congrats!
Gen IVs are monsters with bolt ons

[IndyRon]

Nice setup. I'd attribute the absolute numbers to dyno variance. 650whp on a mustang dyno is 680whp+ on a dynojet and we all know a stock heads cam car is about 600-620whp on a dynojet SAE. Its really not important though, dynos are tuning tools anyway. Track MPH will tell. Either way, ~150rwhp/230rwtq on the spray will definitely be fun!

[Ninjazx71]

Shop posted the last dyno video to their page... enjoy.

Really cool. What tires are you going to use for street driving?

I was running PS2's (345's) but switched over to Nitto 555-Extreme Performance (335's) a little over a month ago. They stick alright, but not as good as I was hoping. Have a few sets of the 355 P-Zero's from that Tirerack special last month so will be putting those on at some point. May just say screw it and do a big 'ol smokey burnout on these Nitto's for fun and then put the new tires on... not sure yet.

For the track I have a set of 18" Mickey Thompson ET Street's (345's). Those things hold pretty damn good on just the motor, so hoping at a prep'd track they will hold just as good with the spray.

What 18 are you using for the back? I was going to get a set for the track and wanted something cheap. Thanks and again, awesome numbers!
