2012 rcsb, 12.69 @ 113

2012 RCSB, Harrop SCed at 6-7psi, W/M injection, on 95Oct. Hit the track for the first time. Best run 12.69 @ 113.

Averaging 2.2s 60 ft. Got to improve on it. I had 305/45R18 semislicks on rear.

will keep you posted.

 

What track?

 

I have oem Crank Pulley. Just replaced the 80mm SC pulley with 65mm Griptec hoping for not more than 10psi.Will tweak the fuel as well timing tables to check the boost first, then work backward from there.

With supporting mods such as interchiller to keep IAT as cold as possible (in addition to WMI), not sure how much horsepowers can stock bottoms handle. Hopefully nothing will be broken soon.

Will keep you posted

 

So far so good.

With 65mm pulley on Harrop sc, Boost peaked at 10psi.

At 18* timing and 10.7Afr, there is a significant increase in power. Draggy 100-200 kmph says 9.5s.

Will post dyno numbers shortly.

 

Hit the dyno today.

648whp on dynojet, 20* timing and AFR of 11.0:1.

With slicks, it should be good to get high to mid 11s in 1/4 mile hopefully.

 

648!

 

are you running a bigger intake inlet? 4.5"?

 

I have 5” intake, and a custom made NW 103mm throttle body. MAF is maxing out sometimes, so might try either 5.5 or 6 inches.

 

Pics por favor.

 

Awesome! That is very quick indeed and nice power! Curious about the details of your build. What mods to the fuel system do you have? Any transmission mods?

 

Welcome from NY.

 

wait a damn minute....@rcsb2012

2WD?

you were able to hook that much power in 2WD?

kudos.

Don’t need all these mods now, just making it ready for +800hp in the future, not on this engine though.

 

2wd yes.
Have not tried yet on 10psi. I am ordering 33x10.5x16 M&H slicks soon.

 

Have you weight the truck as is?

 

Not yet

 

Pics here

 

For a ballpark reference, my 4x4 is about 5280 lbs.

 

Nice, I'm gonna empty the truck before heading to the track next month, just weighted it another day and was at 6999lbs ......

 

Nice to see someone else building an RCSB for the track!
As long as you can get traction, you'll be hitting mid 11s in no time.

 

Hi Viktor, i am actually inspired by you, supercharged, and BRX. I hope so, just ordered something a little different on the rear, 33x10.5x16 slicks and 3.9 open rear diff. However still need help on getting front runners.

 

Nice!

 

Ah the Genius, i was just thinking of putting a reply to check you out ,on this guys thread, haha ,
