Okay, okay. You can laugh. No biggie. Anyways.. What is it? Does it replace the TPI unit? Is that why it's so expensive? What kind of performance difference can be seen on a stock L98 with this thing?
The superram replaces the runners, plenum and base manifold of our L98 intake (the sexy looking part everyone notices under the hood of early C4's). The new superram plenum is much larger and wider than the long narrow stock plenum. The Superram runners are half as long (essentially 90* instead of 180*) and much larger diameter. The Superram base manifold (the part under the plenum you can barely see) has much larger tubes (also called runners) than the stock base manifold. If matched with the right cam (LPE 74219) it makes a lot more torque and a fair amount more Hp than the stock TPI setup. If you just put the new intake on, with no new cam, you won't get much better performance. Someone here will respond with an engine pic of superram v. stock TPI before too long.
I hope my fiance will post here because he knows A LOT about it. He had one on his 90's 383 stroker. However, it was on the original motor before it was redone. I believe the numbers were fairly impressive. The car was a 6 spd and he is a great driver so maybe that helped, but the change is probably static. Anyway, I think his stock times were 13.7/13.8 at like 101 or so, and with Borla mufflers only and the SuperRam upper and lower he ran 13.2/13.3. So it made a fairly big difference on his car, not to say every car would be that good, as it seems to vary. Basically, to get anywhere with modding your Vette, to really open it up, you have to get rid of the original TPI system. It was designed for the 305 motor, not the 350, so does not flow as much as it optimally should for the demands of the 350. Hope this helps a little...I will tell Lee to post his experiences for you. :)
with everything the SR is supposed to go with, and a new set of heads from AFR, id say you could get in the 350-375hp range on a 350 and over 400 with a 383. And a LOT of torque.
Thank you very, very much! Being that I just saw a 97ish Mustang GT with the plate 8URVETTE, I will make this my first move after the car is running perfectly. My plans are still to next week put on Daves90's 90 rims, then to buy and install White Lightning's 89 sport leather seats, then have my springs and Bilsteins on.. After that, all I need is to replace one or two of my fuel injectors (trouble starting after warm) and then I'll buy the SuperRam. N.P.! It's about $1000.00? How much to install?
This will get me into the 13's the way I am now? My mechanic says my car feels strong so I'm assuming it's tuned okay. I'm still not completely clear on how this relates to the Tuned Port Injection. Do I still need to replace that? Is this more of an Intake mod than a Fuel Injection mod?
Sorry for all the silly questions. I'm learning slowly. Hey, you all WILL help me get this car into the mid 11's or 12's. I'll do whatever I can with the motor this Summer - then next Spring I will stroke to 383 or 396 or whatever the heck you's tell me to do. :lol: :yesnod:
I forget what the SR costs, go to http://www.lingenfelter.com and check it out. But they did raise the price. Yes it will get you in the 13's if you install the whole package, and you mightneed new injectors, especially if one or two is bad (the rest are sure to follow). Id get FMS #24lb injectors, not the Accel that is advertised at Lingenfelter. Of course, you wont get any huge benefit from the SR unless you get the 219 cam and a custom chip to go with it. Installation is a B**** with the SR. So i dont know what someone might charge to install it. It is just a new intake replacement, it doesnt directly effect the idea of Tuned Port
a word of advice, dont spend all your money on mods right away, since youre new to the car, drive it a while before spending too much and see what might break or what it needs
Yes I had the Super Ram on my 90...When it was completely stock it ran 13.80's-14.0...with Borlas and a K&N it ran 13.7's @ 100...With nothing added except the super ram it ran 13.20's @ 107 every time...It is a great intake....well worth the money that they ask for it....
Hey Vic.. I hear ya. I know I can just go and do the installations you did and get in the 13's.. I'm not sure which direction to take. I think I'm going to start a post asking for a mentor. hehe. I don't know for sure which mods should come first and where I should really begin.
Like I mentioned before, I'm just looking to get the car running right before I start doing anything. Once it rolls perfect, starts right up and has a stereo with a CD player and an antenna that goes up - I'll be working on performance. This will probably be at some point in June..
I appreciate everyone's input! It really helps.. Now lemme go and get my mentor post started. :crazy:
Cool.. If you ever come down to New York, let me know. I'll let you see how fast you can make it go. :lol: God knows I probably couldn't get a ZR1 to do 13's...
As has been stated above, the Superram is a great induction system and will really come into it's own when you swap it from your 350 and mount it on top of the stroker. LPE uses the 383 stroker and Superram combination on their $14K stroker package and makes about 450 hp and 480 torque! That is significant!
On your stock motor it will allow your motor to breath better and further into the rpm's. I'll send you an e-mail with a picture of mine. The SR is not cheap, or easy to install, but it is a good place to start. :cheers:
I am putting a killer 383, that I bought off this forum, in my 89 with a SuperRam on top of it. After doing the research it is the only choice, for my application, that will provide enough flow for my worked over 383. If I were going to rev it higher than 6K I would probably go with a MiniRam. I am kind of tempted to go with the MiniRam now, because it looks so clean and is much easier to install. Just to let you know, putting a SuperRam on your car will be quite a bit more work than just bolting it on. It will be worth it in the long run though. Right now I believe the going rate for SR's has gone up considerably, something like 900 for the bread box and runners, and over 600 for the base intake. I got lucky and found mine on EBAY, fully ported with a 58mm TB. Good Luck.
A 383 is a great motor. Lee's 383 with LPE 219 cam, AFR heads, SuperRam, etc (don't remember the whole list, but the motor was about $10k I think total and sounds A LOT like the motor described above) put down 36x rwhp and 420rwtq <--- :eek: Comes to 435hp and 510tq @ flywheel. It ran mid-low 11's at 120+mph. Would pretty much run down anything on the street! It was a blast. But I do recommed the SR...I think the price is around $1200-ish if I am not mistaken. You want to get both the upper and lower, as I have heard it's really the lower manifold of the current TPI setup that is the culprit on the restriction. :cheers:
