Possibly before rev limiter settings decided upon? We could go back to no rev limiter days:

BlueOx

I'm guessing there may be different rev limits via Driver Mode selection as RC states.

this makes me feel ill^^

So he says it has more power and torque then the bmw 4.4 tt. it would make sense if they tested the lt1 against the one in the m5 (N63B44TU) which makes 439hp and 479tq. Thanks for the link very informative and interesting.

VRMMMM

That would be friggen AWESOME!

Sullyman

Go to approximately 34:01 in the interview. He talks about how they compared the LT1 to the BMW 4.4 Liter Twin Turbo V8 and how the BMW engine makes similar power to the LTI. In fact he goes on to relate that the LT1 makes more torque and a bit more power. Google BMW 4.4 Liter Twin Turbo V8 specifications and see what you think.

Glad you guys enjoyed the show....!

mr Lee was excellent!

He did say at 1000 rpm the LT1 makes more tq than the great 911 at peak tq levels and Mr Lee was quite proud of his engine...

Sad to say no e85 capability on the vette which I believe is a mistake....a ton of corvette owners could give two craps about decreased mpg and if we could get an extra 30hp and 30 lb/ft of torque without chewing away at fuel lines etc....we d be running E85. I realize it's not often available but still....we would find distributors if it offered a performance improvement like .3 th and 3 mph in the quarter...

I thought Mr Lee was a bit off in his logic with regards to what corvette owners want...yet I assume it was the corporate line to control costs on a low production vehicle....such as corvette. I believe E85 Capability on the trucks gives GM fuel mileage credits as opposed to just gasoline capable...also makes GMs cash cow... it's truck lineup look GREEN.

PeterD 's persona is a bit snobby but he's a nice guy underneath...the show from last week he goes on how he digs the convertible styling much more than the coupe as does Jim Hall from 2953 analytics....

Hey BlueOx, what would be afoot? Besides what RC said about different redline for different modes. What are other possibilities?

Thanks,

Keagan

You may be able to spin it to 7100 but I bet peak power is done around 6500-6600.

BlueOx

I have no idea but what RC said makes as much sense as anything.

I thought months ago there might be a track tune key fob similar to the Mustang "Trak Key" that could change the computer tune. That would be similar to what might be happening here with the Driver Modes but I'm just guessing.

BlueOx

Thanks again JerriVette. I thought this deserved it's own thread!

ZL-1

That's amazing! With so much torque at 1000 rpm I wonder if the LT1 will feel nearly as strong with the taller gearing of the base car's manual trans as with the shorter Z51 gearing?

RocketGuy3

I came here to post this. I got love ya BlueOx, but 20:00 was a terrible estimate of where to start watching, heh. I want my 3.5 mins back.

RocketGuy3

That's pretty normal...

Where's JoesC5, by the way? Is he willing to admit that he's wrong yet? Or is it still too early for him?

And you, too. I guaranteed it would be over 450 hp, iff'n you recall.

RC000E

Spoken like a true sam90lx...misses the whole point...has to say some negative bs...

Read about stretching a gear when road racing then get back to me. Even if it doesnt make power extra rev to work with cuts track times...same as increasing slick size to avoid a shift just before the traps to cut your et...

jdhommert

So it looks like the 4.4tt makes at least 500 hp/tq.....

Jawnathin

Yup. I like having the additional gearing whenever possible, one of my favorite things about the LS7.

In addition to stretching a gear, its possible for the manufacturer to use a shorter gear instead and get to the same MPH as a taller gear, allowing a better mechanical advantage in putting power to the ground.

And lets not forget, the more revs, the better it sounds!

There is a lot to like with 7000rpm.

mattkilla2015

There are different variants to the bmw engine ranging from
402hp/440tq
439/479
547/500
550/500

BlueOx

Yeah but the point he was making is that the twin turbo BMW engine that is closest in HP/TQ to the LT1 is 40 lbs heavier and 4" taller. This helps keep weight low.

sam90lx

I never said it would not be over 450...It would be a FAILURE if was not over 450!
