From what Ive read the Lingenfelter Accel superram plenum and runner setup is the way to go. According to the book I read it kicked *** on any other aftermarket big runners set. Im going to get one with a 58mm throttle body and 1 3/4" headers and 3" cat back (either flowmaster american thunder or HOoker with aerochamber). That should be a nice setup for my 91 350 formula. All I need is money.

 

Read all the hype you want but i'd talk to people who've used the stuff before

 

From an emission stand point.......Yes. But there are other systems out there that are easier to work with and equally, if not better than the superram. TPIS's Miniram and Holleys' new Stealth ram are two of the more popular ones.

 

thanks for the alternate product info. I willcheck those out. Lingengelter is very expensive, that's why I made the money comment. YOu are saying the that Lingengelter is good to pass emmisions testing but also good on performance? The others you mentioned will still allow me to pass an emissions test right? I have to to do that here in Houston now, as part of Harris County plan to clean up air quality here.

 

I love my SuperRam.

The performance difference between the stock runner set-up and the SR was incredible.

Yes! It is expensive!

Yes! It's a pain in the butt to install and tear down! (I'm getting a lot better at it though)

Emissions legal is plus. For you. Not for me.

58mm throttle body is WAY too big.
52mm is the largest I would go on anything. But that's me.

If you're going to do the SR then get a good cam right away and SERIOUSLY think about some new injectors . . .

Any other questions we can help with?

Check out Buckeye-ROCs car. He has a nice SuperRam set up that seems to be working well for him.

There are other SR owners here that can help too . . .

 

Thanks, Its good to hear from guy who have actually used the stuff. Yeah the 350 cid motor seems to be right on the border of the 52mm and 58mm throttle body. I guess it depends on what else you have done to it. Lingengelter has a table and as I recall the 52mm is recommended up to like 400HP, which my motor only dreams about. I guess I should go with the 52mm, but shoot, if I ever do get it built up like I want I'll have to buy another tb. Ill probably be to old to drive by then anyway,

 

I can't think of a reason why anyone would NEED a 58mm TB.
It flows TOO much.
There is NO reason to go more than 52mm and some people think that the 52mm is too big!

I basically bought my new TB because I had nothing better to do and I had some money to blow.

Don't waste your money on a 58mm.

Now that my engine is pretty much done I need to start tuning and unfortunately that means chip burning.

I recently got my scanner cable and software and now I need to get all the crap to erase and burn custom chips.

Just more ammo for the wife to use on me - she hates it when I spend money on a 13-14 year old car . . .

 

The world wont collapse when you use a 58mm TB, and if the engine is strong enough I seriously doubt you'd notice any loss in performance, in fact some people post ET drops with them. However I do agree its unnecissary.

Why is that unfortunate? Prom burning is a beatufiull thing, the $150 for a pocket programmer makes more sense than a new TB just cuz you got the money. You'll enjoy it once you start doing it, and love it when you watch your ET drop

 

The SR is a great intake for making HP and TQ up to around 6000 rpm. I love the SR. My combo drives very close to stock, until you get on the gas, and could easily be a daily driver. I've also ridden in a car with an LT1 intake swap recently done. I like that intake too, although I would use it with an entirely different approach than I did for my car. Do a search on the SR vs. MR/LT1 debate and you will find a lot of info/theories, including my own. Bottom line is whatever your goals are and how you want to go about reaching them, RESEARCH what combos others have, what they run, what they say about them, and choose an intake/head/cam/gear/stall combo that you decide will fit your goals best.

A SR on a stock engine with untouched heads and cam, will probably not get you through the 1/4 mile much quicker. If you buy it on the premise that you will later get some heads or head work done and a cam, then go ahead and get a SR. I would DEFINITELY do the exhaust right now. Save the throttle body til later. I have a Ling 58mm on mine, but only b/c I found a good deal on it used. I might do a little better w/ a 52mm, I might not. But for the price, I couldn't go wrong.

 

I have a Superram (Base and top) on my bench ready to be installed. Along with LPE headers, 58mm and 219 Cam. Check out the Corvetteforum.com and search. That were I get most of my information. Look up Scorp508. He's putting out 322.1 rwhp and 362.4 ft/lb without tunning.

Thanks for the input guys. by the way I looked up your car Buckeyeroc, as was suggested by the earlier guy in this thread. Very nice. The exhaust was my next mod because its not too exensive, besides the car will sound good. Then Im going for the SR, then probably cam, heads, etc. if Im not to old by then, haha.

 

I'd spend the money on chip burning stuff before doing any of that. I bout a fastjunk chip, and the car runs beautifully at wot, but poorly at part throttle. Also, people think injectors need to be changed with other mods. I totally disagree. I've pulled 107mph trap speeds with my STOCK INJECTORS. You're still feading the same sized engine, so don't waist the cash on those untill you got more cubes.

 

Hey BuckeyeROC, are you still running MAF? You burn your own, right? I'm having heck with my tune after changing so much stuff. I'm considering doing the 730 MAP swap and start over, but I hate to give up on the 165. I'd like to look at your .bin if possible.

With a mass unit, it is only going to read what the mass can put out. The 58 is no diffrent. Now when your talking a ported Super Ram and ported heads etc, you better have some thing to flow it out. A cam and atleast Slp 1 5/8 dual cats or what ever you perfer.

 

I'm still using the MAF 165. I've burnt 1 chip so far. ARAP.bin with a 750 rpm idle, no other changes. I'm VERY SERIOUSLY considering changing over to a speed density setup (730) this winter. Until then, I will try to tune what I got. I did hook up the Moates and found that I'm running pretty rich and get knock counts and my timing is being retarded. But I have not had the time to burn another chip yet.
