How much power?

[Lucky161]

This is sort of a tech question, but I can't get on the tech board, so I'll ask it here. Chris B suggested that a twin turbo Olds V8 in a front engined streamlined body might do 260. Well forget the configuration and the bodywork, but what kind of horsepower would this generate? Earlier Indy cars with turbos were getting around 1100HP a few years ago and I think some F1 engines were doing 1200 or 1300HP with a 1.5L engine. Would a 3.5L with unlimited boost put out more hp than a big block Chevy or Ford with unlimited boost?
Top Fuel engines are reported to put out in excess of 6000HP, although I am not sure how the figure that. I have read that no dyno exist to measure that much horsepower. Perhaps they measure fuel burned to reach that figure?

Nitromethane has something to do with it to!!

A 3.5 Olds Indy motor, twin turbo, unlimited boost would put out about 1500-1800 hp on methanol before it would self destruct.

Remember the Quad 4 built by Feuling for Foyts Aerotech made 1300 hp on 2 turbos with 2 liters. But block had pass thru studs thas clamped the top and bottom ends to the center crankcase. And it was on the edge of grenading.

Don't want anyone to get the wrong idea. I am not in anyway interested in turbos returning to Indycar racing. But wow! 1300hp from 122 cubic inches. That's over 10hp per cubic inch. And the 1.5L F1 engines were getting that too. Awesome, but not for Indycars in my opinion.

Here's a good site for the Olds AeroTech:

They would have to go back to the old starters that it took a giant to handle to crank them over instead of the 20lbers they have now.

F1 was getting those numbers in qualifying trim only, and remember, those engines didn't live at redline all day long. raceday engines were more like 700HP.

Today's motors are good. Today's cars are good. Today's speeds are good. The grass isn't always greener you know.

Another Fantasy Island post!

The Olds is stressed out to the max as it is now and has the reliability pegged. GM is going to busy dealing with the 35A. Besides, there aren't any front engined Indy cars and won't be ***** !

Sorry if you are offended Mackie. I don't know how much plainer I could have said it, but I said to start with that I thought this question belonged on the tech board. I then only mentioned Chris B post to give a background of what made me think of the question. Then I specifically said to forget the configuration. And finally I came back I did my best to make it clear that I was not proposing any such thing.
The only other thing I can think of is that if you see something that you are not interested in or that offends you, that you hit the back button on your browser and you will quickly be taken away from the offending post.
If the monitors would like to move this somewhere more appropriate, I have no problem with that.

No problem with your topic or the thread, Lucky.

Just a little problem with Mackie's post. But not for long

A problem with my post? The unlikely prospect of a front engine Indy car has been beat to death for weeks, I am concerned about the credibility of this great site when this kind of foolishness keeps coming up!

As to the rest of my reply, I stand by my comment on the present GM engine. They had an immediate answer the last time an Infiniti won, I don't think they will this time!

Maybe I was out of line on the turbo issue, so I'll answer the question, how much power, the sky is the limit. How much boost will the engine stand. The 3 liter IRL "GM" should produce over 1,000 hp before the explosion. As we have seen on the other side and at Indy's past, the turbo is an open invitation to cheat.

In my opinion this site has such great potential for posting valuable information and answering legitimate questions that it is a shame to spoil it with foolishness!

This site is great for information and questions like the topic of this thread. It would be interesting to know how much boost an Indy engine could handle before exploding.

Totally Unrelated:
I also wonder how many miles an Indy engine would last in the Opel Astra V8 Coupé . It is rated at 420hp (I think).

For you who don't know what I am talking about Opel runs the Astra in the DTM with the 4.0l Indy engine. They Produce 462hp. I saw that they had also built a number of street cars with this engine.

I am moving this one back up to see if anyone else has anything more to add to it. Most of the responses were at least interesting to me.

the 3.5l Aurora engine would produce 1,400hp @ 11,000rpm with 80" of boost. It would produce 1,800hp with 100" of boost. The block would spit the crank out on the ground at about 850-900hp. The aurora is a purpose built engine that was designed to make 750hp, it is not designed to handle much more than that.

They would actually be easier to turn over. The Turbo engine wouldn't have as much compression or cranking pressure as the N/A engine.
