When people run these 4150 is it primarily for motors that spin to the moon? If got an 11.8 416 running a stock L92 intake a 90mm Trailblazer SS intake. Is there is an intake where large gains are to be had I'm extremely interested.

 

The single plane intake is what helps spin to spin high. The 4150 just distributes air to a single plane better. I wouldnt say that 4150 flows more air per-say. My experience says 4150 style has a MUCH snappier throttle. I was using a 4150 carb on a ls2 though so im not 100% that would apply to efi, but i dont see why not.

Single plane is also better for nitrous distribution on non direct port big shots.

Turbos dont seem to give a **** what intake you run. Or atleast less so than n/a and nitrous combos.

 

4150 throttle bodies are better for nitrous as well

 

So happy to see this! Keep up the good work!!

 

Made some time to get the Quick Performace 9” in a couple weeks ago. Dirt track racer 81 once again to the rescue. 10+ years of bailing me out of tight spots lol

Setup is a Quick Performace 9” narrowed .5” per side from a factor 10bolt
Strange aluminum center section with spool and 4.30 gears
40 spline axles
Wilwood drag brakes drilled for factory 6 lug pattern (still had to grind these a little for my bogarts to fit)















Snuck out to the track on a normal test and tune night a couple weeks ago to see where it stood. 60’ is off from where I feel it should be but I think I’m going to chalk it up to wore out tires. No videos or anything as I went by myself

On 91 octane and full weight (4550) exactly how I drive it around town

FF to this week. I managed to talk my way into being invited to the Street Outlaws daily driver race. I called our friends at Nitrous Express to order one of their SAFE stand alone fuel cells so I could put some c16 in it and put some bigger nitrous jet in it...welllll, then all the sudden stand alone fuel cells weren’t allowed. Which meant I had to do what I’ve be procrastinating...switch over to e85. It’s one of those things I kinda wanted to do any ways, but didn’t really want to do because I do drive my truck all over and e85 is really available everywhere I like to drive. But, it was pretty painless since I already have the big DW fuel pump and injectors, other than draining out the 26 gallons of gas in my tank. I haven’t re-dyno’d. Tuned it all with street driving. I feel that the truck runs all around better/smoother so I like that.

I’ll go ahead and spoil it for you and let you know I didn’t win the daily race lol. But the truck did surprise some folks

 

does the trans always run that hot? it wont live long if so. guessing the AWD jeep took the daily driver race again. that thing scoots pretty good on the street

 

No. Only when the converter is unlocked for awhile. But this transmission has been going in this truck for 5 years. No telling what it was treated like in the 70k miles it spent before that in the at&t van it came out of.

And no

 

Spoiler alert! LOL. figured out the street traction in that thing yet? ever considered trying spring sliders? I've been trying to get someone in the full size community to try them out. they are commonly used in the s10 world and worked awesome on my s10. I think they could help the rcsb trucks, but nobody is willing to try new things anymore. you and Tyler seem to be the only ones willing to work outside of the cookie cutter bolt on builds now days.
