Roush TVS1900 4.8 results
2 Attachment(s)
I finally dyno'd my truck. its been done for a little over 4 years now and have ran it many times at the track. My brother is doing fab work part time at a shop and they wanted me to throw the truck on their new dynojet 248. first 2 pulls it spun but the last pull we tightened it up more and added some weight in the bed. I actually ran the dyno which was fun :D and i decided to make pulls locked in 2nd gear. I didnt trust the tires or driveshaft to that speed. I'm counting the last run as the real numbers 551rwhp 537tq. About 50 more hp than i was expecting, and didn't expect it to pull clear to 6800 without falling off. mods are in my sig but in case they change.
stock ly2 4.8, only opened enough for cam roush tvs1900, snout modded for 2.8" pulley, 12-13 psi intercooler tank mounted at 2nd battery tray alky control meth spraying a hefty amount 212/222 115lsa cam. pac single springs push rods stainlessworks 1 3/4" headers, this was dumped under the cab 4l80e locked converter in 2nd AFR is around 10.8-11.0 I think thats about it as far as hp mods are concerned.

Nice job! I wish I had grabbed one of those blowers when they popped up a few years ago.

That little guy is making some steam!!!
Do you have the stock balancer on there? Knowing the abuse the shorter stroke crank can take I would love to see you cram a little more boost in there. Go 8 rib with an OD balancer and see what happens... I bet the results will be awesome. Also FYI the calculator I use puts you closer to 600 at the wheels based on weight and MPH. It would have been interesting to see how a 3rd gear pull would have worked out! Also I'm curiour how that circle D converter acts off the line? I would guess it flashes really high for you. |
Tim z has a 2.5" pulley on his..... Just saying

I've always admired what you've done with that 4.8!
