Wow. Would you mind sharing your setup with me? I ran 9.87 today with a 1.47 60 on slicks. I have NO suspension mods. Not sure what works and what's a waste of $. I'd like to have a street tire that doesn't explode at every crack of the gas. There are car clubs racing and the local airports also...

Auto, Lund tune and elliptical. No tune revisions. Thanks folks, I will check the inlet side for a leak

Any Whipple owners experience any "return to idle" issues. I have one that just developed. Jump on it hard and it is lazy to return to idle.

NT05r's are the only drag radial I find in a 20.

How fast have you been on 20s. I'm running 20s on the street and would like a tire that doesn't combust as soon as I crack it in 1st or 2nd. I'm looking for options and I'd like to hear some success stories before I replace the skins. The car runs 10.0s pretty consistently and I'd like a "street...

Yup. 115@ 6500. 133@ 7500

I've been running 9.90s -10.0s. I want to be running 9.70s without adding more power.

Does anyone have any comparative data on this? I'm running 28/10-17 Hoosiers on the back and 275/35-20s on the front. I don't want to spend the $ on skinnies/wheels If there isn't much of a gain in et.

Sw headers, no fowlers, 7200 miles on the whole setup. No problems yet

I hate to perpetuate some people's ignorant negativity about lower gears for the S550 but I too am trying to get ahold of a set of 4.11s from U.S. Gear. I would love to try them out. I am working on a 1st gear elimination tune to launch in 2nd. Do the math and look how it would improve rpm drop...

Does anyone have comparative #s on the track between big fronts vs skinnies. Im trying to improve the 60s, cut better lights without deep staging on a pro tree and and of course improve my et. We have local races up here that run an open comp format with a .400 pro tree. I'm getting killed on...

Sorry, I misread the post. I see now. I feel dumb. Great #s.

You using a controller for the nitrous? Or hitting it with 150 at the kick?

Now before everyone proceeds to tell me how I'm going to scatter this 6r80, know that I'm very aware of the whoas of trans brakes. I've been bracket racing for 25 years. I want to be able to run box classes with a delay box from time to time. Does anyone have any TECHNICAL feedback? Thanks

Agreed. With that power it would you'd need to 60' 1.50s to have a chance at 6.99.

Here's a photo of a perfect example of this https://drive.google.com/open?id=0B9zSWKyrSCkIX2FWcER6M0E1Rnc And to stay on topic, radials in the front can have a tendancy to "follow" grooves in the track essentially dragging the rear wherever the feel like tracking. It can add to The Whoas

I will do my best to explain. When you launch with slicks, the tire wrinkles, softens the shock, extends the footprint and allows the car to rebound forward. This is of course well known and the reason we use them. We spend a lot of time understanding the dynamics of the tire in the first 60...

It's a tough decision. I have both. If I need to drive to a event or local airport grudge race, I run dr's. If I'm looking to run consistently quick passes and be able to be competitive in bracket racing, Slicks. Think of your application. What are you doing most? You can drive slicks on the...

I bracket race my car. I load the Hoosiers in the trunk and toss them on when I get to the track. I hear a lot of people complaining about the sway. Yes it sways. I believe if your not used to running drag slicks (on any car) then it will take some getting used to. I've been racing slick tired...
