Performance Questions 225 vs. 360
Bill,
So exactly how are you helping the original poster again ?
Either help the original poster,or build a car that runs.
Until then all your hot air is...well hot air.
This is the crux of the Original Poster's first note in this thread:
"I'm open to any kind of modification suggestions. I'm going to have the engine out to clean it up, paint it, probably rebuilt it, and generally get it looking nice. So I'll already be in a great position to do a little hot-rodding on it. I've read that turbocharging the engine makes a pretty big difference. Any suggestions on a good economical rebuild that involves that?
Essentially, as I said, I don't really want to invest the time and money if it doesn't mean being able to outdo one of the small block v8s at a comparable price. I like thinking outside the box, and I certainly know that the slants can be made to whip up on the larger engines, but I was curious if they could do that at an economical price. Thank you in advance for all of your help."
I showed him examples of what he could expect by building a turbo motor, through the videos on You Tube and gave him examples of different ways to accomplish that.
I pointed out that the engines that were demonstrated in those videos were not loaded with high-tech, expensive paraphrenaila such as roller cams, roller rockers, electronic fuel injection nor did they use elaborate (read "expensive") ignition systems.
Pretty basic stuff.
He's an intelligent guy and I'm sure he came away from those discussions with the realization that the facts presented were not not just a lot of "hot air."
If I posted ANYTHING that wasn't true, please tell me what it was and I'll apologize to everyone concerned.
Insofar as MY car is concerned, I told you why it has taken so long to get it "operational," and that we're making progress with it. Today, we took it on the freeway to ascertain the tuning aspects with a F.A.S.T. wideband data logger, and to try out the Snowperformance alcohol/water injector (BoostCooler.)
The 02 sensor responded with readings in the 11.5-12-5 range (a little lean for my tastes) but the Boost Cooler was maladjusted to the point that it was literally "putting out the fire" on the plugs, becaause we were runing the larger of two jets that had sent us, and had it starting spraying at 5 psi, which turns out, is way too early. That was our fault and has been corrected.
The hardest part of a turbo installation like this (IMHO) is the "tuning" after all the hard parts are installed. That's where we are at right now, and with zero experience, I don't think we're going to get all this figured out in a day or two.
But the fact is, when it comes to this discussion, how MY car runs is entirely inconsequential RE: the facts I have presented. The videos prove what
can be done, regardless of how well or how poorly MY car runs. Don't kill the messenger just because you don't agree with the message.
With all the evidence presented here with regard to the difficulty in making good power out of a normally-aspirated slant six, and how MUCH power is available with a hairdryer, on that motor, do you think it makes any sense at all to build one without forced induction?
Yes, Guzzi Mark's car would seem to be the exception to the rule until you consider his CONSIDERABLE expertise in getting power out of this motor (not everbody can make the kind of power he does,) and how very LIGHT his car is (2,350 pounds.) That's a good
thousand pounds lighter than the average Duster/Dart of the 1970s.
I hope that somebody got some good out of all this. I am a 2-finger-typist and it takes me forever to compose one of these pieces.
I'd hate to think it was all just for naught...:banghead:
