GT350 vs. Z/28

[thePill]

Your the one crying foul. Look at all the other cars hp and then look at there stock hp before you put more egg in your face.

PRESS RELEASE. The 302R is around 400. But you need to consider that this IS RWHP. Crank output is NOT used in Motorsport. Balancing is determined using RWHP.

The Boss 302S uses nearly the same engine, PCM's are different.

That said, EVEN IF it was both crank, the Boss is around 400 and legal. The z28 is around 470 and not permitted in GS.

Do you think IMSA put a 58mm restrictor on a 400 crank horsepower 302?

That's around 340RWHP Ya know...

If the 470 on the LS7 is crank, it would be legal at 400RWHP BUT, still have a 70hp advantage.

Reality, the Boss 302 is about 400 RWHP. The 70HP advantage is one of the reasons the z28 has been successful.

Not brain surgery...

Here's a towel, wipe that egg up.

No, there is no way IMSA and SCCA make you engine dyno. All classes are based on RWHP output.

I didn't read where it explicitly states that the power measured by the organizations from the rear wheels. But perhaps I over read that.

Cry all you want, a restricted LS7 is stronger than a Boss 302 by a decent margin.

You're right, the LS7 is a better motor.

Maybe Chevy should have just tried to make a complaint engine. It would have helped...

Well you said the PWC class is a 400 RWHP max class but then you say the Boss is "probably" making 408 RWHP on an engine that was specifically designed by Ford for this racing. According to your "facts" Ford couldn't even build within the parameters of the rules. Now if that 400 number was a +/- bench mark as I suggested, then yeah seems fine to me.

I like how an LS7 loses 35hp with an 80mm restrictor while you push the idea that the Boss is a 480hp engine with a 60mm restrictor.

Is the Boss number a fat fingered typo? Probably, but it's on the official site, which you used as a source earlier. That's the only reason I brought it up. The 35 hp loss with an 80 mm is entirely possible if it is crank loss and not RWHP loss.

How about this, try making an efficient and compliant engine.

See above. Per your own statements Ford didn't even do that with the Boss engine.

Those are 2010 boss numbers, now they have 450 hp. That 20hp less then the Z with 80mm restrictor.

Oh now they have a 450hp version... Oh, you mean like always???

A 450+HP Boss 302 makes around 400RWHP with the old 62mm restrictor.

Are you telling me a 520hp LS7 makes 420RWHP (which is still over 405) with an 80mm restrictor?

Wow!!!! HELLO PARASITIC LOSSES!!!


Disclaimer.... A LS7 using a 43mm restrictor makes 425RWHP in SCCA (or 25 more than the Boss and still 25 too much).

Your telling me the EXACT same engine loses the SAME EXACT OUTPUT with an 80mm vs. 43mm?

Egg????

 

[200MPHCOBRA]

What are you talking about?

Sorry, I miss read your quote. But rest assured, they are not pulling these guys engines to do a dyno test. Its not practical. You might see a tear down if someone contests your car. Rear wheel is more accurate for this instance anyway. A stock Boss will make about 380 to the wheels, with a tune, and no cats, maybe 410-420. That is real world. Nobody is going to pull 480 to the wheels on manifolds and just a tune. 480 flywheel is hard to believe with any intake restriction added.

You are all mixed up. The GTS Z 28 with a 43mm restrictor makes 425 crank hp down 80 hp from stock. The Z28 with. 80mm restrictor makes 470 crank hp down 35hp from stock. How hard is that to figure?:headbonk:

If you look at all the cars racing, they list stock hp at crank with no restrictions, or less with restrictions. For example, the Camaro is listed at 415 hp with a 48 mm restrictor. You really think that's rwhp when it only makes 426hp stock? I never said the Boss makes 480 rwhp, but could at crank. The 302s has Fords race ECU which the regular Boss does not. So nobody knows what hp increase that brings. But a race ECU for race fuel could easy bring 30+ hp to the crank.

Just shut up please...

No Motorsport Organization uses Crank Horsepower. The balance of performance is taken from the wheels.

You also know it's not a stock LS7 right? No matter how many times they say it, it is not.

No Cats, 100 octane, PCM...

When the Boss had a 58mm restrictor, it produced 380-390RWHP. I'm anxious to see how Chevy went from 525+ Crank to about 420 (still too high) only using an 80mm restrictor.

Explain please...

 

[02gtnh]

You answered your own question. Truth hurts.

Debate over...

80mm was 470hp and 475tq.

FYI,

A 5 liter engine using an 80mm Throttle Body and a 58mm restrictor makes between 380-390RWHP. (400RWHP initially)...

A 7 liter engine using a 90mm Throttle Body on an 80mm restrictor makes between 460-480RWHP.

The effects of the smaller engine/throttle body are greater under restrictions in the Boss 302. Not to mention the Boss starts with an 80mm while the LS7 used an 80mm restrictor from a 90mm throttle body.


Victimize all you want, the z28 IS NOT losing more power than the Boss 302. Sorry, not happening.


This argument is pathetic, no one is going to believe a 480hp Boss 302.

It has been well circulated, by me, that the class targets were 350-405RWHP for CTSC and 300-400 for PWC GTS.

If only IMSA used crank HP, they do not....

Thanks for playing...

 

[thePill]

That didn't take long...

z28 starts at 3400lbs and 80mm, takes half a season to react...

GT350 gets an automatic 58mm restrictor before even its 1st qualifying and gets 50lbs after its first win in the second race.

...but the z28 is the victim here...

Stop making up numbers to try and justify your findings. There have been many z28 Dynos making 450 rwhp, so how is it getting 460-480 with a restrictor? Show me one proof of that. Just admit you don't have the answer.
