oops well the cam change still applies. If I remember correctly the BRE pro ram was designed to make more torque in a more useful rpm range for the lt1 and it needs more cam than the lt1 intake required. I dont think it was a bandaid for top end loss, seems like it just needed somethign different to work right in the same rpms and obviously kept its midrange advantage over the lt1... Ill have to do a search for that intake never followed up on the results... seems like this intake was done a while back with the same intentions.

 

The only Problem I see is definately the Cost, , , I mean a bolt-on shopper with a thousand to blow should just consider an S-Trim Vortech kit??? am I wrong? on what planet does anyone (who's looking for best bang for the buck) drop over a thousand for an intake for a 10-50 HP increase

 

People drop nearly $1000 on some catback systems for 10 or 15 HP.

 

Um since when are new strim kits a grand? They are much more expensive than that, and don't say a used kit cost a grand because we arent talking about used intakes here. So compare apples to apples...

And a lot of people don't want to go forced induction and reduce the life or blow their stock bottom ends. And when you are trying to maximize your n/a performance a new intake manifold (which is expensive) is something that eventually has to be addressed.

 

True more cam, but it is also designed to make a decent more HP also, not only TQ.

 

You guys do know the lid warpage is really not that common I didn't have any issues with mine. But I am gona stud my SR so I dont have an issue when I bolt the charger to it. And also you a SR is not better or worse than a a LT1 intake just different. It gives you alot of torque down low which in my opinion LT1's and LS1's lack.

 

I'm going to chime in here since I've been discussing with Ed at LPE on changing over to the Superram on my LPE 383 car. The warpage problems with the lid were addressed a while ago by Accel. They now make a billet lid that will not warp. Also the LT1 Superram is specific for our cars and is slightly shorter to clear all under hood issues. John was never a fan of huge cams and they still only recommend using a specific cam with this intake. I spoke at length with Graham at LPE and all of their R&D, dyno time, and durability testing was with the 219/219 560"/560" cam...Period. In 1995 Car Craft, on a stick car 383 set up with the intake and small cam they got 415rwhp/430rwtq...what the article didn't say was that further tweaking got the hp to 425rwhp!!! TQ curve was FLAT.

The bottom line here is that if you are a daily driver and wants to to some racing, and have a set up that works well, year after year. This is the set up to go with. Its not cheap by any means, but I should see substantial gains with this set up...I'm slightly biased because I have one of their engines, but I've raced the crap out of the car for 10 years and have never even had the valve covers off..Ran an 11.90 last weekend at 117 mph on radials with 3.42s...Not bad for a ten year old motor...My car is going back in March for a freshening and this conversion. I'll let everyone know what happens..

 

CatBack is an upgrade that has everything to do with sound and not much to do with power! I know some people think so but when I did my cat-back I noticed Not much 1/4 mile time increase over stock, I just think that 1000 is a bit steep, But then again where does it go on the top end? which if I'm not mistaken is where the LT1-4 makes it's power! the Super Ram moves the torque down to the 2-4000 RPM Range Right?

 

i may be interested in picking one up for my bolt on/roller rockers car..think i would see any gains on the track?

 

sounds like if it was done up correctly it would not lose any top end but gain a lot under the peaks... and it would be about 1400 bucks...500 for base and almost 900 for the rest.

 

Keep in mind that the LPE SR intake was designed to work with those smaller LPE cams John liked so much. I wouldn't be surprised in the least if you didn't find favorable results using the SR and the more popular grinds guys here like to use (847, CC306, etc).

-Mindgame

 

Yeah my guess would be the hotcam/cc305 ish cam sizes would work better with it but maybe not those exact cams... is the 1/2" clearance built into the base or the runners and plenum since there is only one plenum runner option but 2 base options, L98 and LT1.

 

One of the blower guy bought one of thiese in 97. It fit under the cowl fine, you just could not close the hood.

Great if you want to pull stumps BTW

The one "I" would like to see out again is the TPIs Mini ram for the LT1

 

It's really pointless to put a SR on a blown car, all the advantages of the intake go out the window when the blower raises the intake pressure positive.

I would sell the SR when you throw the blower on there and have the LT1/4 intake matched to the motor and the heads.

I agree compeletly. A bigger cam is needed if you want to get more RPM out of it. John never really twisted those EFI motors of his over 6000rpm many times.


Ummm I think you completely miss the point here. The LT1 intake is not that good and guys who need more TQ have the traction to get it down. Sounds like you need better tires!

I don't know about you but 40 ft lbs more, 40hp more and 30 ft lbs average is going to make something a HELLA lot quicker. Small cam is not going to do that. 460-470rwhp Hyd Roller motors need something like this to get there.
