573 not low 600's again.



Like said not all dyno' are happy and tell you that you made super great power that leaves you getting spanked by a lower powered car

597...Same dyno me and buddy use. This car also had a stage 1 ported blower.

This one made less then you with same mods...

Many including myself claim it is a bolton. It is like porting a stock manifold. Mine made 530std with a cai, pulley, tune. Not sure what it makes with the cat deletes. A full bolton car should make 600+std.

That car is not full boltons it does not have longtubes, inlet, t/b or a port.

Yo dawg im going to port my heads and claim car to be bolt on. Seems legit.

I just posted a bunch that none made 600whp with bolt ons. And STD will read higher by about 4%. And that why you always see poeple coose it over SAE. When talking more power that 4% grows in power. There was just a thread on SVT about it. SAE vs STD was almost 50whp difference. On same car same pull.

correction factors:



"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque. Friction torque can be determined by measurements on special motoring dynamometers (which is only practical in research environments) or can be estimated. When estimates must be used, the SAE standard uses a default Mechanical Efficiency (ME) value of 85%. This is approximately correct at peak torque but not at other engine operating speeds. Some dynamometer systems use the SAE correction factor for atmospheric conditions but do not take mechanical efficiency into consideration at all (i.e. they assume a ME of 100%).

STD or STP. Another power correction standard determined by the SAE. This standard has been stable for a long time and is widely used in the performance industry. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard."

Same as every where says. 4%

LOL..yep.

Again port is not a bolt on. And 127mm cold air betting they did TB. Either way makes even worse it made 573whp. LOL. And it says full bolt ons. So its full bolt ons. We don't know what they didn't list.

They are not full bolton cars and yes a stock ported blower car is still a bolton car.

608sae with stock exhaust. I can post more if you would like

No it's not...what a idiot. A pullied car is not a even bolt-on car IMO. How can you change the atmosphere a engine runs at and it be a bolt-on?? You sure as hell can't port a blower and be bolt-on.

automach1

Wrong you are a idiot if you think porting a stock blower is not a bolton but buying a aftermarket intake manifold is. Exactly your opinion.

The I guess we could port our stock heads too.....I mean all this **** bolts on Like I said, changing the atmosphere a engine runs at is not a bolt-on. If it was the a turbo/blower would be a bolt-on also.

Don't see how it don't get much more bolt on than a pulley swap.

HioSSilver

I never said it wasn't easy. It's just not accurate to what a bolt-on is. You can't change the atmospheric pressure the engine runs at and consider it a bolt-on.

The gt500 that put a car length on me made 612whp. Not sure about the blower port but it was pullied to the moon, had full bolts ons and rear race wheels.

Heater

The rule of bolt on's, is the engine can't be opened up. Have never heard of atmosphere stipulations put on it.

what about a boost controller on a turbo car. Now we arent even changing parts out... but atmoshperic pressure is changed

You're then bolting something on to manually ram more air into the engine.
It gets really gray then. Kinda like changing your cam timing electronically in a vvt engine. I think it's out of the realm of bolt-ons a little.....but technology is wonderful and it looks like we're gonna have to get used to it.
