MTW Stage 1 vs. Stage 2 vs. Stock all on my truck.
Well, I've gone from a stock turbo to a Stage 2, back to stock (after Bill at PHP stole my Stage 2) and I'm now running a Stage 1. All my testing has been done on a 2006 F250 ECLB 4x4 w/5R110 on 35's. My mods are as follows. S&B CAI, 58v QuickTricks FICM with PHP tuning, MBRP 4" straight pipe, 6.4L banjo's and custom tunes from Quick Tricks, TSD and IDP, stock injectors and fuel delivery. There are sh*tloads of other mods on the truck, but I feel that these are the important ones pertaining to the turbo performance.
I'll begin by saying that the Stage 1 & 2 are miles above the stocker. My truck loves the extra air and runs smoother, faster and gets better fuel economy on both turbo's. Both of these turbo's used the 13 blade turbine wheel so the exhaust note changed very little. The intake however does have a more pronounced whistle, but not enough to annoy my pregnant wife, so I'm gonna say it's very tolerable.
OK the Stage 1. This IMHO is a very nice turbo for someone who wants more power, but will never go beyond stock or 155/stock-30over injectors. The reason I say stock -155's is that this turbo will completely clean up the smoke from these injectors and keep the EGT's well within acceptable limits. This turbo will provide quicker boost with no dead spots and lower EGT's. Over the stock turbo I've noticed a 100+ degree drop in EGT's, BUT REMEMBER, I am running the Hercules 100 FICM tune. This tune removes all fueling restrictions on the low end so it is a HOT FICM tune. Any other FICM tune would see noticeably lower EGT's, closer to 200*+ (from what others have consistently reported). The back pressure has been between 1.27:1 and 1.41:1. This turbo has netted a 2mpg gain over the stocker that just came off. The power is good and the truck is noticeably faster, especially on the bottom end. Getting out in traffic is not a problem. This turbo made 473RWHP on the PHP dyno in 80*+ heat and high humidity on a Gearhead tune designed for the stock turbo. The Stage 1 will run on whatever tunes you already have (including stock) without any issues and noticeably more power, but some tweaking of the tune will further benefit performance. The tuning is still being worked out and we'll have more on that soon. As soon as I get a tune for these turbo's that I'm happy with, I'll let anyone interested know who to call and what to ask for. As for towing with the Stage 1, I havn't done any yet but will this week, however it won't be horribly heavy until I change this FICM tune.
The Stage 2. The thing is beautiful. I was extremely impressed with this turbo. The power was noticeably higher than the Stage 1. This turbo cleaned up whatever tunes I threw at it. The EGT's were 200*+ cooler than stock on all my tunes. It doesn't spool as fast as the Stage 1, but is still as quick to light as stock if not a shade quicker. Back pressure was between 1.16:1 and 1.35:1 depnding on the tune I was running. My truck produced 485RWHP with this turbo on PHP's dyno. The ambient air temp was 80+ and very high humidity. This turbo has produced 560RWHP on a truck with 190/75's in 90*+ heat on PHP's dyno. I believe this turbo could be used on naything from stock to 190/50's (some smoke at WOT) with great success. This thing is moving the air boys and girls. I was also able to net 23.5+MPG (highway driving 60-65mph with a little stop and go through a couple small towns) before I took it off the truck on a QT Looney Wild track file. The power was unbelievable. I could destroy the rear tires with no effort, but the truck remained as streetable as the day it rolled off the line until you squashed the skinny pedal. Again, this turbo will run on whatever tunes you already have (including stock), and run well, but will benefit from some tweaking in the tuning. The turbo exhibited very little lag, no surging and smooth consistent power throughout the RPM range. The truck cruised faster with less effort and was overall much happier with the Stage 2 over stock. I did tow with this turbo as well. 14K behind the truck and the turbo performed flawlessly. The load moved quicker and was held at speed easier with far less down shifting. I was running a IDP Agressive tow file with turbo brake for this test. My EGT's stayed below 1150* (ATLAS 80 FICM tune) the entire run. Ambient air temps were in the mid to upper 80's with normal GA humidity. The Stage 2 is a 64.7x88mm compressor wheel in a .72AR housing with a .90AR turbine housing. The new Hybrid turbo that will be debuting within the next week or two will be a 64.7x88mm compressor wheel in a .58AR housing with a .90ARturbine housing. The expected HP difference is 5-8 in favor of the Stage 2, but the price difference is looking to be fairly large. For these reasons the Stage 2 may soon be replaced by the Hybrid if the testing goes well and it performs as expected. As soon as I get the Hybrid you guys will get a review of it as well.
I've tried to give you the best reviews as possible with all the info I have, but please feel free to ask any questions you want.
