^^^ What he said! Too take advantage of mods, especially the headers.........you need uprev.

Grizz7122 · Sep 15, 2011

and I would think the 35s have something to do with them too

PAPARYNO · Sep 15, 2011

well a dyno can read anything...track numbers are what it is about...look at my dyno numbers

i thought stock titans were 305hp and 379ft-lbs? thats what factory says...

very interested in hearing what an UpRev will do for this!

All manufactures data is engine horsepower/torque. The dyno is telling you the true HP at the rear wheel.

+1 - all manufacturers HP is at the crank...

Dyno is true test of power to wheels..

OP Uprev should have been before the dyno... You need a tune with those mods.. Prolly get another 30 whp with a tune bro..

My mods are similar to yours. Im going to the dyno tomorrow and mainly wanting to check afr. I will report what I get tomorrow. I suspect im lean at wot. Is so uprev will be called tomorrow evening.

Not only does manufactures measure fly wheel HP but if they advertise 380HP that is 380HP at the Fly Wheel at sea level.... So you will lose a lot of power through your drivetrain anywhere from 15-25% depending on your setup. You will also loose power with a lift (driveshaft angle) bigger wheels and mainly altitude. So between drivetrain loss and altitude I guess you caqn loose about 20-35% of your 305HP depending of how high in the clouds you are.

I am at 5280 avrg (Mile high city) and my 0-60 is + - 12 seconds...

Dont worry about numbers.....a dyno is only a tool thats it..bgger tires on a dyno always eqaul lower numbers unless you have the correct gearing...with 3.73s or 4.11s you would be over 300RWHP

dodgehemi0 · Sep 15, 2011

You need to get an up-rev tune those headers make her run lean i had that same set up once i was dyno tuned with up-rev my numbers well you can see them in my sig and that was with the tires in my sig to.

08crewcab · Sep 15, 2011

king what happened with the SC???? forget about the dyno #s run your T at a track and see what she does! uprev is needed though with your mods

nightowl · Sep 16, 2011

I went to the dyno this morning at east Texas motorsports. I was quite impressed with my numbers.
O5 FFV 2wd 2.93 gears
S&b cai
No converters!
Stillen LTs
JBA catback
Stock mid pipes
Bdgt +2/93 tune
Stock tires

Temperature was 83 and 29.40 humidity. Dynojet revealed-
307.47 hp and 352.69 tq with stock tune
310.98 hp and 376.82 tq with 93 tune and + 2
93 octane with NO ETHANOL gas in tank.

The bdgt made 27hp more and 33lb/ft over the stock tune where it counts at 4100 rpms.

Most of all my AFR WAS 12.24 AT WOT!!!!!!! WITHOUT UPREV. DON'T BELIEVE WHAT THE BDGT TELLS YOU IF YOU HAVE HEADERS. GO TO THE DYNO! I will have a youtube link in a day or two of the dyno run...

Rig is at the shop for the SC install right now. Should be done monday.

Get your truck weighed. I wonder how it compares to mine. What we really need is someone without a lifted truck and huge tires like Gweasel/Deerslayer/Paparyno etc to run a supercharger and get some track numbers. I know my size and weight makes the supercharger look useless.

honda250xtitan · Sep 16, 2011

those guys would never dare to put a s/c on their trucks. not with stillen's reputation on here. lmao.

jpac811 · Sep 16, 2011

lol I know they wouldnt but thats my dream. Almost everyone with a S/C is lifted, heavy with huge tires and crappy times including myself. It still hasnt been put to the test. My truck is at 97xxx miles and still no problems though. Id let any of those 3 guys try it once especially the FL guys since I go down there often.
