Hello there fellow AFM members. How goes it? Haven’t posted in here in some time and had been having some recent confusion with my original plan for my car, which was mainly a 302 engine with a single turbo. Lately I have came across some new information that has got me thinking about change my plan and going in a complete different path. In my mind there has been 3 major questions that are ahrd for me to completely grasp, as I do not know that much about cars (although more since I’ve been in this forum).
1.N/A or Forced Induction?
2.Modded Auto or Six Speed Manual?
3.Engine Build. Which cubic inch build has been known to be more reliable if so?
The cross road I am with NA and FI began when I saw on the steeda site about this new generation whipple that is suppose to be the next step in Forced Induction for the S197 stangs. When researching that turbocharged vehicles tend to run hotter than s/c vehicles, that changed my path from turbo to s/c off the bat since this is a street car, not a drag car. But then, I was thinking just staying N/A and just having bragging rights on the modded numbers of an “all motor car”, and potiently keeping things from breaking? I guess this is a tough question to ask or answer. I don’t really know or can find the pros and cons of NA vs. FI anywhere that consists of S197 information.
Then came the tranny question to me. I rode in a manual stang the other day and no doubt it does drive different, and that I had kept hearing from ppl that a manual has unmatched power to an auto, that where the auto beats the manual is on a track and that’s if the auto is modded. That’s what I heard. Correct me if I am wrong. But I guess would Beefing up the 5r5ss work better for my conditions or a 6 speed manual?
Finally, the engine question. The only thing as of now that will always be on my to do list is an engine build. The only real engine build I have heard of is mark’s 298 build and a popular 302 build. Now I have heard of some other new engine builds beyond the 5.0 range and would like to know what engine build would be a great foundation or start for the car. I heard different stories here in this small town in texas and would like to get you guy’s expert opinions on this. Does all of this fall into the same question? Lol I’m sorry for this HUGE post, but I had to let you gusy know. You guys basically built the car. Of course, I’m not worried about replacing other aftermarket parts if ened be as I am in search of a C & L intake in replace of my K & N. If you guys got more questions on the car, I’m here all night to answer and thank you in advance for your opinions.

I've always been a F-body builder and driver but recently, 2 associates of mine got into stangs and picked up a couple S197's. I've done extensive upgrades on these and both are kept N/A and they are top performers, no FI needed. Running with N/A or F/I all depends on what your goals are. If you're looking for a 300-400hp daily driver, then N/A is the way to go. If you're looking to exceed that then a supercharger is the way to go. My advice is to build up your N/A S197 to its full potential and if in the future you decide you want to supercharge it, you can go with a RoushCharger that was built to be installed on the stock s197 motor. This particular supercharger won't destroy your engine internals with excessive boost and stress and is a great poweradder good for 115+hp and 70+ft/lb torque, safely.
As far as transmissions go, the manual trans has always been the unrivaled choice when going for max performance and handling.
In my experience, the Windsor 302 block has always been the solid choice for all of my builds. On my current stang, I started with a 5.0 302 block, then I bored and stroked it to 331.

1. bragging rights to who? because normally when you brag you are smoking people. Ask STL how much money it cost him to get his 420 some thing rwhp. Compared to what it costs to get 420 some thing out of a blower. No offense but the only guys you will be able to beat are more stock style GT's with bolt on's that are S197's. You will be neck and neck with rouses and saleens off the lot but all they have to do is pop a tune in her and call it a day. I would still build your motor. When you say build an N/A car also I am talking about a PURE N/A high compression huge lop in the cam type of car. A car that if you dare put a blower next to it, it will fall like superman and kryptonite because of the compression ratio.

2. What do you want out of your car? Do you love driving a stick? Do you plan on ripping apart the front suspension and doing some major weight reductions and drag racing your car. Or do you want an all around daily driver that you can have fun any where you go with. Not saying an auto you cant have fun with because I plan on going to an Auto but I also want to get my car into the 9's one day. How serious do you want to take drag racing compared to the love for driving a stick? Sticks are awesome and so much fun so that is up to you. Ask your self do you want a drag car or or do you want a fun street car? not saying an auto is not a fun street car but a stick is just way more fun.

3. 5.0 Stroker is the way to go. I will bake MMR with there motor any day. The power I was able to make is over any other P1SC I have seen at the amount of boost I have made. Not to mention 5Twenty with his KB. His car is making unreal power at the amount of boost he has. That shows that MMR is building some great blocks. I would love to see what his NA power is as well.

Some of my statements were a little exagerated, so all you auto guys dont go saying you can still have a street car if its not a stick or you dont have to gut your front suspension to have a drag car. It was a comparison.

With todays technology N/A is a thing of the past. With FI taking hold of every thing and there mod motors being small blocks you really have to take advantage of the fact that yesterdays way of adding power by going to the junk yard and pulling a 454 is over.

As for a turbo creating to much heat, I have not heard any issues from turbo guys with there systems yet. All the systems from any reputable shop should be fine. Not to say that they do not heat up more then a blower does but you should not have any issues. Just do it right and get every thing jet hot coated.

Also Twin Screws also get a little hot as well and roots you can cool your breakfast on top of it. If you want a cool running blower get a Procharger my S/C stays pretty cool. But if I can do it all over again I would get the MMR Block and run a 100 shot for sh!ts and kicks. Then do a larger Turbo. Probably a custom T80 and I would of got the Auto from the start and not a stick.

I've never ran this car at a drag strip, and might a few times just to see what its made of. But It's going to be just a fun street car. my ultimate goal is to have more power than a zo6 out of the factory and still have fun going through town and around curvy roads and such. I don't mind relearning a stick, its been a while since i drove one, as long as it has ben true to be a bit more "fun" on the street. what do you think about this new whipple generation II s/c?

I haven't had direct experience with the Whipple II yet but I've heard nothing but great things about it. All kinds of increased efficiency, reduced heat production and it's positive displacement design give you maximum low-end torque as well as high efficiency for maximum top-end horsepower. The gen II has a unique 3/5 rotor profile, which allows it to flow more air in smaller packages, at lower temperatures and drastically lower the dreadful parasitic drag. Overall, I give it an A-.

Alright I took a look at their regular crates on MMR site. Should I get a custom one or is one of these crates they provide good enough. their site doesnt show the HP/TQ numbers either. hmmm too late in the day as well

well the power on the motor is going to depend on your build. There is no way that they can tell you how much power it is going to make with just a short block because heads, cams, exhaust, and other bolt ons play a huge part in that
