Indycar chooses 2.4 liters as not yet the right direction.

The new indycar engine czar has confirmed indycar will use, “2.4-litres while retaining a twin-turbocharged V6 layout.” all the while pointing to new manufacturer involvement. Their other public thoughts pulled together point to Cosworth saying they want to develop a new engine and Indycar wanting a manufacturer to attach their name to it. This is a useless move. How?

Porsche and Subaru are instantly out of the picture with the flat design they sell. Anyone with 4 or even 5 cylinder engines gets no displacement break (also subaru and porsche plus anyone markiding big in the boosted inline market.) to compensate for lost valve area in engines with less that 6 pistons.

I’d like to see another manufacturer. Who wouldn’t. Id like more than 3, but limiting what a manufacturer brings to the table limits what manufacturer truly want to be there if nothing helps sales. Is it good though?

Well, identical cars and engines eliminate advantages other than outright power and economy. Im certain that Indycar adjusts boost for all on all tracks to regulate safe speeds but if anyone shows up with something they cant control unbalancing all their competition balance, like ultimately low CG and shorter engines making for smaller polar moments, then other manufacturers who don’t build and sell such things may threaten to or outright leave.

I say so what, but i also say indycar does have to protect the show. Has a right to. Nobody liked it realky when F1 aided Ferrari to dominate excessively in the Schumacher years. Or mostly the whole CanAm field in ‘73 was 917/10's. But even when a dominant engine was in force, like the Offenhauser was at indy, it wasn’t a problem as long as everyone had access to one.

The ideal solution here really cant rest in regulation. It more or less has to come from the teams making choices. Give an engine limit and let the makers provide a solution. We may be very surprised or further excited when Audi brings a turbo 2.5 slanted inline 5 or Porsche a 2.6 turbo flat 4 like they want to sell in the boxter. Or Ferrari tries a 2.2 v8 that will be more thirsty than any other there. A VW vr 7? Whatever. Regulate revs n boost n size. Done. Heaven forbid someone tjinks they can destroke a LS and make a 3 liter version compete. If they truly want indycar great again they must unleash what was great about indycar.

Let the rest of the puzzle fall into place. That appears the only real pick of the fan enjoyable solution.

Porsche uses a turbo V6 in the Cayanne and Panamera

Porsche has literally built almost this exact engine for open-wheel racing before. The 919 ran a V4. The racing side of the business doesn’t constrain itself to what’s happening with the road-going bit.

er, Porsche has vee engines in the Panamera, Macan, and Cayenne. and has had vee (928) and inline (924, 944, 968) in the past.

It took Honda & Penske working together to get Chevy to come back into Indycar. Essentially Honda gave them their Ilmor contract and that Penske would be their main team. This allowed Honda to bring back HPD to making their engines in Indycar.

I think they need to come with a low cost easy solution, and that maybe would be Cosworth coming in and getting someone to badge their motor like Ilmor has with Chevy.

Some would say Ford, but not sure if that fits them right now. Maybe another foreign make?

Either way, people get upset when one manufacturer dominates and hurts the other half of the teams, then they get upset when it’s a single manufacturer and becomes a “spec” series.

V8 i4. None allowed in indycars mandantory v6. They sell a 6 in the suv aparently. But honestly without a flat6 911, or a flat engine history, what are the sales on? Image carrys them

This is news to me, but lets give it some time to let the facts come out. I think the V6 is important as it allows space for ground effects tunnels which are mandatory now days. As for the displacement and also twin turbo, I bet we discover it aligns with LeMans LM2 or some other international formula.

That way, any major manufacturer with an engine in that series has easy entry into INDY and vice versa. It wouldn’t surprise me at all to discover that GM and Honda dictated this so that they could have other places to race their future Indy engines.
