Mopar Performance camshaft help

[BSB67]

Yes, you are missing something. They are about the same as measured at the valve, because the TBR is a hydraulic, the 528 is a solid. I mentioned this before about the lash.

Put in the cam, turn up the boost, hang on!
Lol.
Good luck!
I know how much fun my 89 Conquest TSi was, with the original tiny 13a turbo, turned up from 10.5 to 17 pounds of boost! I had a 16g turbo for it, and some other stuff, that would have taken me to the next level, but I sold all of that along with the car. If I had the opportunity, I would do what my best friend is doing. He bought a JDM used 2JZ (in Japan, engines have to be pulled around 50k miles, and they are sold dirt cheap). He has a good size single turbo on it, a Turbo 400 automatic transmission, and it's going to put out about 500 some horsepower, without losing any longevity at that power level!
All in a red Conquest TSi.
They take curves like they're on rails!

I always liked the styling of those cars

a friend just used that p4120659 .528lift . 284dur @ 0 , .228 int .244 ex @ .05 , its 115 split , installed at 112 . in a street 440 + .03 pump gas with alum stealth stage 2 heads , just a stock build . made 540 hp at 6800 rpm , 500 hp plus at 55oo rpm on the dyno . had a eddy rpm dual plane with a 800cfm carb headers . that cam works well , not sure about under boost . my cam guy can grind you want you can't find .

I think one of the Mopar mags did an article on where a guy swapped in a 340/8-3/4" combo in his driveway.

My best friend is a Conquest/Starion fanatic, and he had a high compression 318 4bbl with some go fast goodies and a Chrysler 904 automatic transmission (or maybe a 727) in a Starion. The stock ring and pinion gearset in the rear axle assembly is surprisingly strong, and a common, cheap upgrade is to swap in the higher (numerically) ring and pinion gearset from a Mighty Max or Dodge (Misu) mini pickup truck, for a 3.90 rear end ratio.
Unfortunately he drove it like a grandmaw heading to church on Sunday, so I never got to experience it's potential, but the 2JZ turbo 6 is going to be a real *** clincher...if he isn't afraid to put the hammer down.

The boat anchor is headed to the machine shop Saturday, hopefully all checks out well.

I hope so too...
Then, turn UP the BOOST!

Thanks! lots to buy before I can turn anything up though I have a feeling somewhere between 15-20 Psi something interesting but not so cool is going to happen, lol.

Very good! I got to considering this cam after recalling a few articles outlining that a solid will behave like a hydraulic of 10 degrees LESS duration. This is a turbo build, (my first) and I have been informed that overlap is to be avoided. My budget on this build has long since come and gone, but if this cam will work, and work WELL, I'll use it, otherwise, it's time to cough up for a custom cam. Until I can muddle my way through the math, it sounds like I should have 15 degrees or less overlap. I'll check with my turbo mentors and see if its workable.

Thank you very much!

Paul, you need to get a hold of my friend Randy if you plan on building a turbo Mopar. Send me a PM and I'll forward you his contact info.

.528 MP / 112 LSA is a great camshaft for a turbo application, the idle quality is near-stock. I ran one with my turbo build for awhile before going custom.

You're not going to squeezing anywhere near 15-20 PSI into a BBM on pump gas [you'll need to utilize a large T-6 or twin T-4's, start studying compressor maps], boost is simply a measure of restriction. On an engine with decent cylinder heads and high displacement, you'll make enough power to split the block a few times over by 14 PSI [theoretically, you'll double your N/A HP at this level].

Dump everything you know about making power N/A and you'll be ready to start learning about your future turbo application.

PM coming, I recognize your screen name and believe I have read many of your posts. I have a T6 75mm Borg Warner. This is an E85 fuel build, my friends swear by it, and it does have a lot going for it. Thanks.

E85 is a perfect choice for a turbo build, but there are some drawbacks. My 470" is lucky to get 10-MPG on pump gas, so expect 6 +/- on E85, which will burn more fuel around town in boost. May also want to run an additive to provide lubrication as E85 may destroy your fuel system otherwise. You'll want to run a 'big boy' fuel pump like a Weldon with a power management unit to keep it from overheating [most have a very low duty-cycle, 30-45 minutes on, 60 minutes off,], maybe even look into a belt driven pump. E85 is much more forgiving on the tune, so it makes sense to swap over if your local to a station that carries it.

^^^^This but test it every time if you’ll use pump E85 and have the tunes to handle the blend swing.

I have an Aeromotive A1000 pump/filters and big lines along with an aluminum cell. I'm hoping it gets better than 6 mpg lol. I know it goes through a lot more than gasoline, but I am hoping the turbo helps with the efficiency, my friends turbo/Gen III Dart gets 17 Mpg.

 

[Paul Secoy]

Block got dropped off today, I am very impressed with the shop and the owner. He was not however impressed with my piston selection, even though the compression isn't very high and I will have 100+ octane fuel, he said the pistons I selected have too much "dead air", (no quench), and it would be detonation prone. Long story short, it's getting a set of JE pistons. An unexpected cost, but he said it's worth it. It will be a few weeks before he can start on the block, hopefully it's usable.

Typically you lose around 30-40% economy going to E85 over gasoline, your friend would be getting 11-13 MPG on E85 with a lot less displacement than you'll have. You'll want a pump controller for the A1000 & maybe even a fluid cooler plumbed into the return system if it's a street car.

Yes, street car with a return system, I will look into pump controllers, I hadn't considered one, thanks. My friends Dart is getting 17 on E85, 392 cubes, about 15 less than me, but a much more modern engine design. His is carbed also. But much more power than I will have. So I will either get 2 or 20 lol, hopefully not too awful.

Not even sure how that's possible, but I would take it for sure! I've heard guys getting anywhere from 2-mpg to 12-mpg on E85, all depends on the build.
