Got my baseline yesterday.

427 RWHP 428 RWTQ

Yeah that's what I'm hearing.Stock 427 HP.Maybe as you go on ,COA ,Headers tune,Headers
Supercharger,meth etc.You will list all of these as you add them.

I think i'm going to supercharge and call it a day.

thanks for posting.

That would be 407 rwhp using the SAE correction instead of STD. Most people report SAE.

Pretty optimistic number for a baseline. I would question the accuracy.

As racerns already stated....the 427whp was using the STD correction on the DynoJet Dynometer. There are less restrictions using STD over SAE. STD corrected dynos usually read ~ 4% higher than SAE (which is what more people dyno with due to being more realistic with real world factors). Using that math...it actually equals out to be about 411whp with the SAE correction (411 x .04 = 16.44, 16.44 + 411 = 427.44)

racerns

It is actually SAE = STD X .95456

It is really just how the Dyno operator chooses to display the data. A Dynojet measures it the same no mater what correction factor is applied to the results. STD correction will always give you higher numbers (than SAE) and that tends to make people happier.

I have it in Standard and SAE I will dyno in standard after every mod so the increase will be measured in the same correction.

What were the numbers in SAE?

mariofromnewyork

Ill print the graph and post it tomorrow.

SA:

This is from a magazine article on "dynojet" dynos.

SAE j1349 correction:
29.23 in/hg.
77 degree temp
0 percent humidity

Standard correction:
29.92 in/hg.
68 degree temp
0 percent humidity

What this all means is that "Standard" will give you 2.6 percent better numbers (very popular for the import crowd). The example the magazine gave was a Vette making 412 (SAE corrected hp). With the Standard correction it made 423. All that you will have to do is multiply your "Standard rwhp" by .974 This should equal SAE (the one everyone uses). Up here in the great white North (Washington) the temps are in the 40-50 degree area, along with 29.9-30 in/hg. So, our numbers are actually corrected down from what it made at the rear. Usually, 96-97 percent of actual posted numbers. If you dyno when it's a hotter temp or higher altitudes the numbers will usually correct up to equal the desired temp, humidity and pressure of the correction factor.

Who cares what the SAE number is if you want a baseline to measure any additions you make--assuming you use the same dyno?

mariofromnewyork

Thank you. I will be using the same dyno in the same correction so no issues. I was just providing info.

motomanvette

407 sounds much more accurate. the baseline number means nothing unless you mod the car and retest on a similar day to see what the mods add. Your car is no more powerful or weaker than 99.9% of the Stingrays out there.

What mods do you have planned?

StingerBG

418whp stock?! God I love these cars! Great #'s! Keep us informed as you progress with mods!

WKMCD

That's what I did. I really don't want to start down the road I went on the last one.

mariofromnewyork

I never owned a supercharged car. How do you like the driveability? I know coming from that stump puller it must feel slow, mine does in stock form and I'm hoping that the Pro-charger can give me that feeling back.

Have you driven the New Z yet?
