you dont know me from adam, so this isnt a “flex”, just a “hey here is me”Regarding power, I am trying to reconcile the statement on Magnuson's website that says "In stock trim with no other system modifications, this kit provides an AMAZING 440hp AND 380 ft-lbs OF TORQUE at the crank, equivalent to ~372 REAR WHEEL HP." But Livernois says "adding up to 120hp peak gains". So per Mag you get ~440/372 and per Livernois you get ~405/345. I wish I knew what I should realistically expect. The Mag numbers are pretty close to Ripp if in fact you get a full 372 at the wheels with Mag. I am interested in RIPP too but I like the idea of making HP at lower RPM. Not because I think I need more power rock crawling but I just don't love doing 5-6K RPM and I want access to more of the power at lower RPM even though I may give up some power at the higher RPM. Having said that the only time I really need more power is in the sand dunes in 4-high so maybe Ripp makes sense.
i have spent a lot of time time talking to ripp, hamburger, people working on magnuson, and now some with edelbrock. Im a former tuner/programmer and tuning beta tester for a major software development firm.
i so far find the Edelbrock the most compelling, and while this is just my personal opinion- it seems the most complete. Ripp makes a ton of power and has a lot of satisfied customers.
They seem knowledgeable and their product consistent. Magnuson is using a big roots blower, and now has a tuner that has some SERIOUS grit. As i said, he has asked to remain anonymous, but his experience and resume making horsepower is considerable. It will be a reliable and powerful tune when he is done, and its already come A LONG way.
ive gotten to the point, though, that i value drivability over outright power. Livernois does a fabulous calibration. But you have to leave the truck with them for 2-4wks to get it done; plus any “delays” that come up. Ripp, hamburger, any other centrifugal are open filter elements. Thats fine for a street truck, but what about one headed to the trail With water and dust? I guess you could fab an airbox; but the PD blowers leave the air box sealed and intact.
with the edelbrock, theyve addressed all the tuning issues to the motor AND the trans. Airbox remains sealed. It shows up to your door ready to bolt on and go. Its been driven in all the conditions you would normally find. The EGR and cam phasing have been properly addressed. The box shows up, and your truck drives more gooder-er by the end of the weekend. No other company has that right now.
my ego wants big power, but is it worth it?
-i want my truck to last 15yrs of use.
-i want a sealed airbox for snorkel use.
-i want bolt on and go with a ready to go tune, not one that requires a bunch of custom dyno and road tunes.
-i am increasingly concerned about the legality of non carb parts. 15 states have signed on to carb so far, and the number is set to grow. I live in virginia. The likelyhood of virginia going carb is in my estimation, high. What do I do if i drop $7,000 on a SC kit and suddenly my truck wont register/inspect because it is in violation? Theres no guarantee you will get grandfathered by the state and no guarantee you can buy a carb approved tune from the vendor later.
-i want transmission tuning addressed. Higher tq converter lock up with high load lock to lock shifting so the thing lasts.
most honest dynos put a stock JL at about 220ish whp. Ripp, Edelbrock, and Livernois all agree on that figure, which tells me they may not be hp accurate with each other, but they all have been calibrated honestly, so its “close”
-ripp nets ~370hp ~320tq. It is by far the most powerful; includes an Intake. No trans tuning. No carb approval. No sealed airbox. Ripp says you may require additional tuning. Centrifugal may not be best option for a trail truck.
-livernois tune of the magnuson nets ~340hp, ~290tq On an otherwise stock vehicle; but includes higher flow intake pipe. I think they do trans tuning. sealed airbox, no carb approval. 4+week vehicle down time. I do not believe the Magnuson will hit 370hp. If it could, i think Livernois would have gotten it.
-edelbrock tune of the smaller tvs1320 nets ~330hp ~270tq On the stock airbox and intake pipe Less under the curve than the livernois, but peak not far off. Arrives to your door as a turn key box. Cheapest of all the options. Carb approved. Trans tuning included. Sealed airbox. No additional tuning required.
i get the urge to go fast, i really do. But i also need to be able to drive my truck 365 days a year. I dunno. Im going to give it some more time and see what this guy at Magnuson gets done and if they get it turn key. I also need to see a no bullshit real dyno of a carb approved tune from these other vendors making more power, because getting it through carb will cost power for sure. I think with my 80mm throttle body, exhaust, and high flow intake, ill be close to the livernois tune. The 1900 is a bigger blower, but the 1320 can handle a stock mk2 Pentastar just fine. Its 11.3:1 compression for fucks sake. You just dont need that much blower to do well. you wont be able to really recognize the full benefit of a bigger blower without a set of pistons at a minimum; and Id bet money that 1320 has more in it with a pulley, and you can run out of transmission quick if you take the 1900 or a vortex trim ripp is using and spin them to the limit.
