I'm not sure what you're considering "high horsepower" but mine seems to be doing fine for the most part. Making at least 350RWHP, have done this before on the dyno. I'm guessing I'm a bit closer to 400RWHP now, estimated by trap speed improvements, about 8MPH. My fuel system is stock short of...

I use denso IK27's with good luck. I have read that the rule is one step colder for every 100hp (crank I assume) increase in power. KC

Not officially but likely. Been hitting about 12psi with the cool dry air we've been having here lately. Let's not forget about all the other mods though..... KC

Went to my local 1/8 track yesterday and had some great results! Some notes: Freshly rebuilt transmission with Raybestos blue plate clutches, IPT valve body, dex3 fluid and a new line pressure cable. Rebuilt and restalled converter (3200-3400). Running on Mickey Thompson drag radials, stock...

I made about 350RWHP on the dyno with about 8psi with my Vortech supercharger. Trapping at 106MPH in the 1/4 mile. I now trap at between 112 and 114 so guessing about 400RWHP. Ditched the intercooler for water/methanol injection so I'm making about 11psi now. Auto transmission BTW. Lots of...

Bad news guys. Went last night to run. Wasn't running too good. Figured out why on the 4th run. I killed the transmission, second gear is gone. Even now with light driving takes about 5-10 seconds to shift to second. Blah. If anyone knows where I can get one cheap LMK please. KC

Hey guys, real quick. Thanks for all the compliments. Going again tonight, weather is going to be beautiful! Will update soon! KC

Sorry guys, I thought I noted some stuff I didn't.... Some recent mods: The car has lost 130-140lbs recently. Did weigh in at 3728lbs with me in it, should now be around 3590lbs or so with me in it. Went to a 1 step colder iridium Denso plug from the iridium NGK's I was using. Took out...

Thanks and sorry! Didn't realize there was a drag race section.

I don't know if I'm the fastest but I'm getting there.:biggrin: Hopefully I'll be running 1/4 again on Friday. KC

On 9/10 I ran at Mooresville dragway (1/8 mile track, date is wrong on slips). Best was 7.874. Last night I ran at at Darlington dragway (1/4 mile track). Best was a 12.516 with an 8.058 1/8 mile time. Haven't scanned the slips yet. My car was not running nearly as good last night at...

Just throwing this out there.... I'm supercharged, about 11psi, water meth for cooling. Have made 350rwhp on the dyno (traping at 106 making about 8.5 psi, intercooled without wm injection) estimate about 390 now (trapping 111-112) and, drum roll please, I'm on the stock ECU! And..........I...

Sooo..... any updates? I found the Megan mounts for pretty cheap but would rather see what you come up with. I'd also rather support this forum. KC Edit: my drive train moves around pretty significantly since putting in the IPT shift kit, I need something soon!

Any updates? I think I may have toasted one of my mounts. KC

I will argue (to the death!) that centrifugal chargers don't do much for low end. It's simply not true. The power is biased to the top end but there is plently of low end to go with it. And, a vortech can be bolted on in a day. By far the easiest way to go and probably the cheapest as well...

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...

Not to rush you David, but when do you think these will be done? How's the R&D coming? KC

I am very interested BTW. Not sure if I'd want solid though, just something harder. Maybe a solid trans mount. On my car, thats where it feels like all the movement is, in the trans mount. All my mounts (OEM) are fairly new BTW, maybe a year old. KC

There's these, not much more than OEM. http://www.tunerdirect.com/9298-lexus-sc400-megan-racing-engine-mounts-p-42225.html KC

If you decide to go forced induction, I suggest supercharging. My setup has proven to work quite well. I've run a best of 12.62 and trap around 110-112mph. The car weighs 3728 lbs with a 1/4 tank of gas and me in it. With Lextreme's fish bracket, a centrifugal blower can be installed pretty...
