Even that won't help. You have people who are professional argument makers. You can post your real world experience, backed up by professional people no less that Larry Meaux and Darin Morgan and they still want to tell you how stupid you are because so and so runs his car on a dirt bull ring with a stupid weight limit blah blah blah. Or how an inline 4 can be compared to a V-8 that has had its architecture blown out beyond what any engineer ever had in mind when designing it.

I mean really...can any thinking, intelligent man not see the folly in such thinking? Let's take a liter 4 cylinder, and increase its bore, stroke and RPM increased in an equal amount to what the standard American V-8 has been and THEN tell me how good the aluminum is.

Not one of us has said aluminum doesn't have a place in engine blocks. If you are under 1000 HP and N/A and if your stupid rules don't allow flyweight shit the cast iron will beat it every time.

I had a customer back in 1998 with a dragster. I begged him not to buy an aluminum block for his car. He figured weight was better than HP. It wasn't. Since it was a rear engine car, he had to add weight to the car to get it to hook and he gave up power.

He stepped on his own dick. The car never performed like he thought it would, but did exactly what I told him it would. A couple seasons later he parked the car.
I haven't had that problem, I have built hundreds of aluminum engines. And had a few back to back te sts. The most I lost was about 1.5 %.
Thank you for speaking in terms of %. It wears me out to see people quote "X" horsepower gains or losses like it doesn't matter what the engine displacement or horsepower range is involved. I recently built and dynoed an aluminum block (Ford Racing) small block. It's a middle of the road street engine that made 1.4 per inch. I used the same exact combination as the previous build except for the block. It was down 1%. I'm not sure the dyno is even that repeatable lol. After 13 pulls the exhaust ports were gray and bone dry. The breathers were also dry. BSFC .39 - .45. I respect Larry and Darin's findings and believe them completely and their findings are probably true in many cases, especially as you approach 2 hp/ci and up.But you can't paint everything with a broad brush.
I, and a few others, have seen 40 hp difference on 700hp engines....482-496 cubic inch FE's.

Exhaust ports were dry on my engines as well. You don't have to have greasy exhaust ports to have cylinder distortion or blow-by.

That's just my experiences.

After 16 pages, I'm sure not everyone is reading every page.

And thanks for inquiring about my finger!

Maybe if we had some sort of database, we could see a trend between blocks and block manufacturers.

Dude I’m not following what you’re getting at.

Make it easy for me, if you have a gripe against me, spell it out.

Do you think I’m not an engine builder or something? I can show you my Federal and state tax IDs if it’s really bothering you that bad. :lol:

Put your big boy pants on, build up some courage, and quit with all the round-about talking.

The majority of my business is internet based. I have engines in 20 states, 8 countries, and 3 continents. I don’t have a storefront on main street but I don’t want one. I have a couple of local drag racers that I cater to and other than that, I stay at my shop and build engines and don’t get pestered by anonymous forum members who want to drop by and act like I have to prove something to them...

If you need references, call Motorstate, Comp Cams, Scat, Molnar, Bryant, Racetec, Diamond, etc., etc., and they will vouch for me.

I know this won’t be good enough for you, as you will pick a specific minor detail and gripe about it, but you can ask if I really care about your opinion.

Too bad that you didn't stop by last month when I had this 1200 hp 556ci BBF pulling truck engine on the stand.

Nice 👍 piece! Where is the like button?
Thanks Keith! Shipped it to Montana last month. Right now he’s severely traction limited....

Not super reliable, but they are good for at least 40 minutes (60-80ish miles, or 240 to 320 drag race runs with hard downshifts included) in road racing trim.

Those engines are all aluminum.
I know this is getting off topic but screw it, this is more interesting than the rest of what's going on in this thread.

Unless you know different, I can think of only one guy that was successful with the 660cc turbo combination and he had a hell of a lot of money into all of it. SCCA threw a restrictor on it the next year, and turbos are explicitly not allowed in P2. The guy did what he came to the race to do though, albeit I don't think anyone would say it was reliable - race pace was nowhere near what it was doing in testing, and he turned it down even further after the first couple laps because he was sitting on a grenade, but it sure did finish the race in 1st. Trap speeds into turn 5 were something like 20mph up on everyone else though.

I've heard tell a few others were working on a package like that at the time, but that was the only one I've seen that worked.
I was hoping you'd bite. Yeah, I remember the restrictor deal, was just speaking in generalities for this audience. I don't really know anyone in the P classes, so I haven't really paid attention other than when Tucker ran his set up.

The 660cc engine I know I think was developed that winter, not sure if it ever ran on the track. It supposedly made 330hp @ 15,500rpm. It was a GSXR-1000cc block de-bored and de-stroked, Nikasil cylinders, zero clearance fit Marine Crankshaft (so had to be preheated just to turn over), and a Garrett GT2860RS with a GT2859 compressor. The people that were associated with it were associated with Loshak, but again, not sure if it was for him. Supposedly it cost $50k to build.

Loshak said a year or two after that he did have one in progress, so probably was for him. Class moved on obviously before it was ready - for that matter he moved on too, isn't he running Trans Am now? I don't know what Tucker was using for a basis - I was spectating at that Runoffs and took some pictures of it sitting, but they were never willing to have the covers off with anyone around. Carbon brakes and monobloc calipers on the car already said enough of Tucker's budget level on that car.

Last I checked he was racing TA2 still - not sure if he's running a full schedule though. And yeah, the Tucker car, while I didn't see it in person, was bonkers. I of course did hear about his security force. :shock: :lol:

The headers on Loshak’s TA2 car are pretty cool looking. The guy who was involved in them, the HProd Honda, and the DSR engine, was Peter Cunningham’s crew chief at RTR.

not everybody, hardly anybody actually, just forum hustlers .com

don't forget, B2 alloy builds are down 40hp #-o
