and just for me to add my two cents weight will make a difference but the faster you go the harder it is to go faster under your school of thought chevy6000vho if i were already running 12's and pushed 8 pounds of boost i would not take a second and a half off but it would still make it much faster. so i know not necessarily what you are saying but do keep in mind that the faster you go you have to spend twice to three times the money or there would be tons of trucks on this site in the tens

 

Hello Mcfly did you f'in forget that the VHO is a little lighter. 13.5 is pretty good for a SS with all stock exhuast. Besides trap speeds show power to wieght a little better. He trapped 98.9-99mph. A little more then you I would say. A converter and shift kit will not make your truck trap any faster. Also agian the SS has a lot more driveline loss. Lets think here....a transfer case, front end and propshaft. Come on give me a break this same set up in your truck would trap 102-103. This could mean a low 13 to a high 12. I cannot belive you made no metion of that little wieght difference and drivline loss.
Also a smaller pulley can net easy 12's. remeber the faster you get the harder it is to pick up a tenth. I know this from making 10 second passes myself.
The Radix is well worth the money!!!

 

It's not that much heavier! Every 100lbs= 1/10 loss in et.
Anyone have the weight of an SS vs. VHO??

Jim

 

so i guess now that i have, volant cai, headers, no cats, magnaflow exhaust, bbk 80mm tb, elect. fans, coils, wires, plugs, comp cam, 3.73's, and oh yea a nelson tune i should be running about a 8.7-8 in the 1/8th then since a stock king cab with a nelson tune can run 9.1 right??

 

well, a stock SS runs roughly a 15.3. simply bolting on the radix and doing nothing else will net you around a 13.9. i'd say that's a damn good jump. on the same hand we have a guy on the site running a 13.5 N/A with a mild cam and the usual bolt on's. sure he'll beat a truck with a radix only. he also put alot of work into getting where he is. a radix can be installed by almost anyone with limited ability and tools and get similar gains to what someone with all of the bolt on's will go. you can't dollar to dollar compare a blower to modifying what you have with bolt on's. a VHO with a radix if you could get it to hook would likely be .5-.6 quicker than an SS (at least the awd version) as only a bolt on. when i say getting it to hook i mean without slicks. the awd trucks aren't using them so why should you get to in the same comparison.

 

yeah i was there with jim. he forgot to mention that his tune had minimal time to relearn. rollin on 20's and a lil weight reduction caught him a 14.3 in the 1/4. makes me want to switch to a lq9 for a little cheaper than getting forced induction.

hey jim, i might have a set of aluminum 16's with a good meaty radial for ya next time we go. well see what we can get it to crank out then

 

the 10.0:1 compression 6.0L is certainly one hell of a factory setup. now if they'd just put that in the regular cabs....

 

That sounds like a plan. I've heard that when you run smaller tires on the rear than the front, that it will cause the ABS light to come on.
20's in the front and 16's on the rear....LOL. If it nets a better ET, then I don't care about the look.
Don't you think that a smaller tire height on the rear will change my shift points? It may cause it to shift too late or too soon.
Don't really know how it will effect it until I try it though.
How's your truck been running?
Have you fixed your bed side yet?

Jim

 

got my check from the guys insurance 2 days ago. im waiting until summer starts to fix it. 2 more weeks and i cant wait. what size tire is on your 20's? the tire height is what matters. the tires i have are 275/65-16. that should come to about 31" tall. i think your tires are 31.5" tall???? if so it shouldnt make a huge difference.

 

[QUOTE=low99silverado]I wanted to try a STS system, but I dont like the idea of the air filter under the truck in crappy weather conditions. I see they have a remote intake, Anyone know where that reroutes to? In stock form do they have any drivability issues.QUOTE]

I gained 200awhp going with the "upgraded" STS kit (GT-67, 9psi, and Methanol). This is with a PIG rich 10.8 A/F ratio. I'm not sure what a Radix would add. Maybe CHarris or someone else with the Radix can tell us what his before/after dyno numbers were to give you an idea?

I do know the Radix will have more low-end torque off the line, assuming you have a factory stall. But I'm 99% sure an STS kit like mine will put out more power. I'm going with a built trans and 3000 stall to remedy the "off the line" slowness. Now, slow is relative, I'm still hitting 5.1 0-60 times even with a 2.4 60ft on the G-Tech. That tells you how insanely hard the power comes on when the boost does hit!

I'm absolutely loving the STS setup and wouldn't trade it for anything. But I have spent more than the $6000 of the Radix kit, not including Trans/Stall. I have no doubt I would love the Radix kit as well. Do yourself a favor and ride in comparable trucks: one with Radix, one with STS, then make your decision. That's what I did...
