Dyno Numbers


Recommended Posts

Just got the car back from the tuner and got the new dyno numbers with the long tubes. For now the car has 333 horse and 309 ft/lbs at the wheel, right at 400 at the crank. I think that's respectable for an N/A car with just bolt on mods. The car pulls through all the gears hard all the time now, which means no easy Sunday crusing any more (not that I'm complaining!).

Nice!!

 

So that is the net gain from :

FRPP Hot Rod Cams

FRPP 62mm Throttle Body

FRPP Intake Manifold

Dynatech LT Headers

 

Is that correct? (and tune as well).

 

(I know that your FRPP Black Cam covers adds some kick, too!!!!)

Usually the loss of power to the wheels is about 15% which would put you at about 382 HP at the crank. But still very respectable. CNC heads would / should put you over 400 hp easily.

 

Sounds like the cam is worth about 25, the TB about 10, the manifold about 15 and the headers about 15 hp.

 

Would love to see pictures and, most importantly, hear s sound clip if possible.

 

Congratulations!!!!!!!!

The 400 at the crank was what the tuner told me, that's not my calculation. I'll get a sound clip posted soon. It was filthy when I got it back so I'm doing a full detail and then I'll pull it out and get a clip posted.

 

I talked to the tuner about CNC heads and for what it would cost me to buy them, have em installed (at the tuner's shop), and his tune I'd be better off just putting a blower on it. He said for the cost the blower would be a better investment at this point. So, now the saving begins for a Paxton blower. I know this is an age old subject, but is it worth it to have SA put the blower on? At this point (with very little thinking) the stripe and registry designation isn't that important to me.

For more power you need to move to East Lansing were the air is a much better quality for tuning. LOL. :hysterical: Congratulations on you mods and numbers. I have considered a paxton for my 07 but, I can't justify the expensive trip to Vegas for it. Harley

Not the best quality, I took it with my phone. But, I think it does the job

The iPhone microphone isn't the best. It just couldn't handle the sound in this one...

Those long tubes and muffler delete sound great. Exceptional!!!!! What is the noise level when driving and is there any drone on the highway?

 

 

The noise level is incredibly loud when I lay my foot into it, but if I'm just cruising around town not trying to draw the attention from the local police force it's not too bad. It sounds similar to car with a performance muffler. If I'm in 4th gear down the highway there's a little drone, if I'm in 5th gear it's not bad at all - once again just like a performance muffler. The only time it's really loud is when you would expect it to be, when you're trying to make it loud or when you wanna stretch a gear beyond 2000 rpm.

 

I took the car out the other day to my city's unofficial drag way (i.e. newly paved stretch of road that doesn't have speed limit signs on it yet) and when I let the motor do it's thing my friends could hear me a good 1/4 mile away - or at least that's what they tell me...

 

To be honest, I can't wait to be rid of them. The sound is great and I love that I can annoy all the people I hate, but I hate that I have to keep looking over my shoulder for those blue and red lights. As soon as I have the money I'm going to pick up a set of the Borla Ataks. With those I can get the same sound but be able to have an actual muffler.

Worth it to have SA put the blower on? Well, yes, if you have the money! Getting it to and from SA and associated expenses can drive the cost up above the quoted price. Myself and others here have gone the DIY route, and quite frankly, I'm very happy and proud to have managed that task on my own, not to mention I saved $6,000+!

 

I originally was going with the Paxton - history with Shelby being the driving force - but after researching all of the options, I went with the Edelbrock E-Force. Straightforward install with only minor hiccups and no major mods required - a reasonably competent person can do the install in long weekend! At the rear wheels: 466 HP / 428 TQ

I wish the e-force was a SAI option. It produces good power with low psi. 462+ is a great amount of hp for a stock 4.6. Should last nearly forever. I don't trust a 550 hp whipple on a stock lower. Like pulling the pin on a grenade and seeing how long you can hold the spoon down.

Sorry 07SGT, I think there are too many of us 550 Whipple upgrades with limited or no faliures to agree with your statement. I can burn up a riding lawnmower given enough time and abuse.

Well, I could be wrong. But we are still talking about a stock 4.6 that does not have forged pistons, rods, or crank. I am sure it can crank 550 HP but for how long. Personally I wish all of you the very best and for the longest time. But if it goes you could destroy the potential value of your SGT. I am sure it can generate 550 HP but for how long? I am sure the amount of track time and general abuse would contribute to its early demise eventually. I hope my SGT will be around forever so I hope to have a SC someday but will limit the boost to 5-7 or 8 psi. But I hope all of the 550's last forever.

Well if it doesn't last, yours will be worth even more after you bolt all the stock stuff back on it! :o

All the tuners and modular enging builders that I have talked to have said that it's 18% loss on a manual car and 20% loss on an automatic. Either way, nice mods and enjoy!
