Daily driver SC400 in the 12's

[scotturnot]

More to come soon, very close to purchasing a set of Hoosier et quick time's.

Should I be worried about anything breaking?

KC

Nah, well maybe breaking the 11 second mark! Fingers crossed!

Kc- did you rebuild your tranny stronger? I think oem a341 will take 350rwhp all day but thats it's edge... I would just worry about launching with those sticky Hoosiers. but a large T-cooler, shimmed shift solenoids and a reworked valve body i'm told can raise that mark to 400-450rwhp.

I am about to rebuild mine in the next few weeks and needed to source an aftermarket valve body. Anyone know where to order/buy?

We will see! I plan to first use them, if possible, at a local track.... in case anything does break won't have to get towed too far! LOL.

Seems as though there are a few faster than me 300's out there, some of them have to be using the stock parts.

I think my two biggest concerns would be the driveshaft and the rear end.

Time will tell!

Good luck Kc, hope you don't mind being my guinea pig but you have one of the only setups like mine so I am very curious to see how much our stock tranny/driveline can take!

Ahh, it will be ok!

If something does go, hopefully it would be the trans or the diff since I have spares.

Been awhile guys. Still running pretty strong.

Haven't really had any luck on the Hoosiers, for some reason my car just doesn't like them. Did run a few good times last week....12.9 something, 12.71, 12.67 and a 12.64 @ 112+ mph. But despite the pretty good times, my 60ft's have sucked. I've picked up quite a bit on the top end mostly from the Suprastick I think.

I decided to try a set of Nitto DR's, 1/4 track day tomorrow, I'll let you all know how it goes.

Hey mate, still running just the stock ECU and MaftPro?

Yup! Have been doing allot of tuning lately. Recently found a few things that the MAFTPro can do that I didn't know about.

Mainly, the VE table can be edited directly rather than just adding a fuel percentage at certain points. Very cool and a much smoother result.

Only got 3 runs in last night. I do have a new best though.

12.62 at 111.xx mph with a 8.16 1/8 and a 1.93 60ft.

I still think I should be getting better 60ft times but again, I only got three runs with the new tires.

Very nice KC! still breaking ground!

Guys, as usual, I haven't had time to post much over here. But, I wanted to let you all know what I've been up to.

Check this out.

Quick sum up. Running a non-intercooled setup, piping through the engine bay with water / methanol injection. Have switched to bkr8eix iridium plugs gapped to about .030. This is one step colder than the bkr7e copper plugs I've been using for quite a while now.

I have been to the track a few times. Have not beat my best with the intercooler setup but have come very close. Ran a 12.63 still far from being tuned right and pinging a bit in 3rd gear, which is why I switched to colder plugs. Was, at the time, running -20 washer fluid with some heet added. I am now running a 75% meth 25% water mix using Sunoco methanol and bottled water. Haven't track tested yet.

Well, that's the short of it. Let me know what you guys think.

Wow! Very impressive 1/4 mile time (estimated) for a daily driver!

...I know I shouldn't ask this, but what kind of gas mileage do you get on a daily basis? I've looked around on the forum(s) and I can't find anyone who supplies their fuel mileage with a modified drive train.

PS: kc95, nice to see ya over here. Can you shoot me (PM me) your phone # please? I switched phones and everything got deleted. You should hear my stereo now that it's finished. :bigeyes:

The rwhp is estimated, the 1/4 time is not. My best time is a 12.62.:headbang: I have a couple of things I'm working on, I expect to beat that time very soon, hopefully significantly.

If you have to ask, don't do it, LOL. Milage isn't as bad as you would think, when I don't drive it like a maniac. But, it doesn't take much hard driving to suck it down.

I'd love to hear the system. I will be going to Zmax on the 10th if it doesn't get rained out. Maybe we can meet up. Otherwise, you know where to find me.
