I most certainly beat the Corvette and it was on drag radials, definitely not stock either. A few guys came up to me after that race and said, “holy crap, is that thing on snow tires?” lol... sure was and the next day we got 8” of snow. Guess who had to park the race car and guess who was out playing in the snow lmao
Love it!!:waytogo:

Very nice build!

How has that throttle body been working? I've been running an LS2 90mm on my Magnusson for a few years without issues but I'm scared to upgrade to a Nick Williams.

Also what do you IATs look like with the chiller? I typically see 10-15* above ambient normal driving and have seen close to 140* after a 1-2-3 gear run.

Lastly why are you sticking with the MAF? I switched to speed density when I first put my blower on and have had no issues with it.

You might look in to the Snake Eater Performance 102mm DBW. Yes, they have a very Ebay-esque name but a ton of people myself included have not been disappointed by their products. A lot of people use their injectors but I'm running the 102mm without any issues. Tuner had no problem with it either. I believe the issue with a lot of these larger DBW throttle bodies was solved when hpt released a patch that addressed it. Best part about the Snake Eater unit though... $275. Not sure what the rules are on linking nonvendor websites, but a quick google search of their name will take you there.

Try not to advertise parts in someone else’s build thread. I’m perfectly happy with my Granatelli Motorsports 103mm TB.

*Also, any HP Tuners “patch” you’re referring to would not fix the issues people have that are making big power or lots of boost. It has to do with the TB motors being strong enough under boost/high load.

Lol just trying to help the guy out since he was curious and price point seems to be a big factor on these dbw units :cheers:

What's her race weight with you in it? We can figure this out mathmatically.

Rear Wheel Horsepower = Race Weight X ((Trap Speed X 0.00426)^3)
Your guess is as good as mine... I don't have a set of scales but one could assume that it's just under 6k lbs. Lets say 5,800 lbs to be conservative.

5800 X ((124 X 0.00426)^3) = 855 rwhp which is pretty close to what I was guessing (curb weight is 5,635 lbs)

That's awesome, always enjoy watching your short clips on youtube! What would you figure the motor's output to be without the supercharger? I sometimes dream of a 402 and wonder what kind of power it would make while still retaining good street manners and reliability for 200K miles.

I’d say it’s probably making at least 600hp N/A. Obviously the camshaft would ideally change with no blower but I’d say that’s a pretty good estimate given the current output. Generally 1hp per cube is standard in a N/A factory application and usually 1.5hp per cube in a high performance build. No reason you can’t have performance and reliability at the same time.
