I think what youre missing is that it is not the GM TPI (except for the fuel rail) or the siamese runners (siamesing the stock base if thats what you did might have been 100% of the problem you had/have with the whole thing!) or whatever it was that you had...:) granted it was made to go on the TPI engines, but it is far superior... It will fit under the cowl...& the plug for the distributor hole if not included is like $10 :) |

Yeah, I need to call LPE and see if it'll fit without major modifications. |
Re: LPE Super Ram's Available again !!
In Lingenfelter's book on SBC's, he mentions that the Superram plenum had to be made about 1/2" shorter than standard TPI versions in order to clear fourth gen cowls.
On a separate note, the Superram will not increase peak HP numbers on an LT1 car! It will give a big increase in midrange torque vs. a standard LT1 intake, but not a top end HP increase. |
Re: LPE Super Ram's Available again !!
Hell that would still be way worth it... so how would the egr and all the little things connected to the lt1 manifold connect on that or wouldnt they?

The Superram is a very good manifold, but the car application should be considered. It would be outstanding in a heavy car with an auto tranny like an Impy. |

and here's the link to my 86 TA i used to have. www.fl-thirdgen.org/mrr23 there will be a graph on there showing the swap from my siamesed stock base and stock runners to the fully siamesed SLP runners and edelbrock base. and here's the dyno graph from when i swapped from my fully siamesed SLP runners and edelbrock base to the HSR. http://stealthram.com/dynoresults.html oh and here's where a guy swapped from the SR to the LT1 intake and as typical of the GM TPI design it stops at 5000 rpms. http://stealthram.com/dyno/superramvslt1intake.jpg and here's the popular hot rodding article on the swap http://www.popularhotrodding.com/tech/0803phr_beast/ |
Re: LPE Super Ram's Available again !!
That dyno graph for the lt1 vs SR intake looks like good strong mid range gain for a street only driven car, just what I was after.
|
Re: LPE Super Ram's Available again !!
you might want to read the article. there was a gain in ET at the track using the LT1 intake. oh and pay attention to how it's put together. then go to www.thirdgen.org and read up on the SR. the box tends to warp. causing vacuum leaks. most will tell you it's a $1200 piece of junk after they've owned one. had to install it more than once to get everything to seal.

Re: LPE Super Ram's Available again !!
The article about the LT1 intake swap was cool. The guy in the article is one of the guys in our car club here in Charleston,SC. I was there that day when the SR intake was being swaped with the LT1. It was cool, and even cooler when that article came out in the magazine.

To use the Accel Super Ram on a LT1 F body you need to purchase the F body upper plenum and runners along with the LT1 Super Ram base manifold. I know someone that can beat the heck out of LPEs price. Email me for more details. LPE gets $865 for the upper plenum and runners and $500 for the base. Jegs and Summit sells the upper kit for $769 and apparently they can't sell the base. I know he can beat them prices as well. If you are interested email me for details. |

Re: LPE Super Ram's Available again !!
All other things being equal, the motor with the highest avg hp and tq will win the race, which is why the superram was developed. Read Lingenfelter's book, that's what his main principle in building motors was, the highest avg hp and torque. For a street car with the proper gearing, it is superior to the lt1 intake and offers a much broader/useable rpm range. I wish I had never sold mine. Experience is your best teacher sometimes. :( :(
Like the stock tpi system, it is mis-understood and has it's place in hot-rodding, being used in a heavier, long-tube headered, low geared(3.08 or lower), 5000-5500 rpm shift point. The first thing people want to do is gear the hell out of the car and shift it at 6500 rpm, which is not what the intake runners were designed for. |
Re: LPE Super Ram's Available again !!
The big problem with this intake is the price. The LT1 intake is pretty good for free. If it's torque you're after, you should put that money into good heads and the right cam (bigger is not better). If it's average torque you want, take a look at dyno graphs on cars with a 230-ish cam and good ported heads. The torque curve is hardly a curve at all. It's more like a line. I have trouble discerning the peak it's so flat. From 2500 to 6400 rpm, my car makes more than 320 lb-ft of torque. It will light the tires up at 40 mph rolling into the gas. How much more torque do you need?
If I wanted more torque, I'd go with a smaller cam. I just don't think the Super Ram is going to do that much to improve things. Certainly not $1200 or so worth of improvement. |
Re: LPE Super Ram's Available again !!
well in those dynos was the cam and tuning changed??? That would make a huge difference since a different cam would be needed to get the most. Then there is the tuning obviously that would need to be somewhat changed... I dont think swapping one for the other with no other change does either justice..
|
Re: LPE Super Ram's Available again !!
must've missed in the article where it said both were wideband dyno tuned.
