Thanks for giving ppl the perspective and keeping it real. 💯 your experience in the race and severe duty arena is much appreciated by many of us. I live how you call out ppl skimping out on compression!!

@benalamedaracing2765 4 ай бұрын

It really pains me to see a promising build strap down with low compression turning potential into an instant dog!

The VW dual exhaust with headers is somewhat similar to a crossplane crank V8, with a pair of cylinders firing close together creating a high pressure pulse as if there was one big cylinder. With the VW the two cylinders fire 180° apart. If a dual exhaust is favored for whatever reason, it would be better to pipe the front two cylinders together and the rear two cylinders together. This would give 360° between exhaust pulses. The closed exhaust valve on one cylinder would prevent any dilution of the intake air with hot exhaust. I do believe that in combination with a merge collector of the two headers would providen the best torque over a broad RPM range. Ever think why Subaru engines have a bit of bark like a V8 even with a single exhaust or turbo. It is the two exhaust pulses, one from each bank, as the cylinders fire 180° apart. To the collector on each side this appears to be one big cylinder on each side. This gives that Harley reminiscent exhaust note. Now if a person looks at the Mazda Skyactiv videos that describe their research into the exhaust and manifold/header design to enable using 13:1 compression and 87 fuel, could provide information on how Subaru performance might be improved or lower ocane (read less expensive) fuel could be used. And gosh with todays prices we sure need to have all the tricks in play to reduce our fuel costs. More good information Ben. Thank you. Have a great weekend Ben.

I swear my old mustang has a chip in it or something, anything over 12* timing in it and it’s detonate on 93. I could put at ten and still could not run anything but 93 in it. Makes sense, it’d walk away from every other stock ish 5.0 it raced. Heck it beat some cars it didn’t have any business doing so. Love your videos. I can’t wait to get my newer to me 95 5,0 hopped up.

@benalamedaracing2765 5 ай бұрын

They may have ramp up the ignition curve or your timing marks are off! They are a piece of steel plate that easily bends and shows you a wrong number a possibility.

Hi Ben, really like your way of explaining how to make power and how to get as much as you can out of everything. I am building a sbc .o60 over 400. 4.185 bore 3.750 stroke. I have a scat lightened crank and 6 inch I beam rods 2.02 1.60 aluminum heads 205 runners edelbrock victor jr. Now I am trying to figure what compression and cam to use. It is going into a 55 Chevy 1/2 ton pickup with a th350 and 9 inch with 4.56 gears. I have been looking at Howards cams 106 LSA and 102 intake centerline and comparing them using the Wallace Dynamic calculaters. I am finding cams that make dynamic pressures of 8.5 to 9.5 and dynamic pressures from 180 to 195+. Those numbers change from cam to cam depending on the static compression that I calculate and duration of the cam. It also changes the effective stroke for every combination that I come up with and also the overlap. What I need help with is trying to find the right mix of dynamic cranking pressure and dynamic compresstion and is it better to have a longer effective stroke ? I am here is CA and will run this at Sears point and Somoa and probably more time at the track then on the streets but I would like to be able to run it on 91 and still make good power. The truck should be around 3400 pounds and maybe less since I still have things that can be changed to make it lighter. Any idea's to make this engine perform would be great. I have a friend that runs a 65 F100 and he is putting a stroked 428 in it so I have to try to get as much as I can out of this 400. Oh yeah I will be running a single 4 barrel. Thanks again for all the cool shows that you are making and all of the very useful and very very good tips and information. Sorry for this being so long. Thanks, Pat

I feel you should talk with Rod/Nolan @ Iskenderian Cams because they have so much feedback from racers like myself on what is the best grind! How long is the longest straightaway and how tight are the corners! In fact Nolan does this a lot for many circle track and he nails the grinds all the time. Google Iskenderian and they are in Gardena in California and just mention my name and they will take you seriously. Nolan is super busy and Rod would also be a good one to talk to.

Ben, I want to thank you for putting the cookies on the table for us to reach. When it comes to measuring cranking compression with a gauge, I have noticed about a 25-30 psi DECREASE after switching from an old-school ford starter to a newer style mini starter. When you recommend a ballpark of 190psi for pump gas, what starter is being used? Mini? Have you ever experienced differing pressures due to starter style?

@benalamedaracing2765 5 ай бұрын

Not really except if the starter really was worn out with very high resistance will turn much slower and the new one will definitely crank faster and posts a higher reading. Normally they all turn close to each other if they are in good shape from battery to starter to the ground/positive connections.

No room for a single 3 inch so you are better off with an X pipe joining both banks.

Also I don't want my car loud. I am building my Vic into sleeper. So a single 3 inch would probably be pretty awesome. I've always been a "duel exhaust with Flowmasters" type guy. But I don't want it loud. Throaty but not loud.

I love the flowmaster sound and it is just about the same if you installed an "X" pipe between the two banks will basically function the same.

I have yet to see anyone with a 10:1 stroker tells everyone he really went quicker at the track with a 950cfm carb! The example I gave is a mid ten sec. engine making about 600hp (426cid 11.5 comp.) and still went quicker with a 750 vs. an 850. What would a 950cfm do? It will dyno well that is a given but we do not race dyno's we race the track. Well I do that is a fact been there many times and done that. In short it is the difference between the dyno world and the world of competition running a race.

@@benalamedaracing2765 I never had the luxery of a dyno for the first 10 years of racing cars but at the track or on the street I knew what worked and what didn't because I was beating guys with bigger engines and a lot more money invested than I did.
