Over the years I've done a lot of testing with these cars. I've probably spent more money on testing clutches than an average build costs. - Not bragging, just saying I've tried a lot of stuff. One thing that sticks out, is virtually all performance clutches require more throw out bearing...

I've never been a fan of the way most others do 4 spider center differentials. The floating cross shaft is a poor idea, adding 2 more spider gears barely helps. The cross shaft is allowed to turn in the housing, while the gear is held flat against the out side. End effect is the shaft becomes...

I've broken quite a few over the years, and the ones in the early transmissions were especially weak. Broke one in my dogbox which I figured out after the fact could have been bad, as you can get a dogbox in 2 gears at the same time then pretty easy. Anyway I finally finished up a few billet...

This is the Build Thread for Lt. Dan - Fastest All Motor DSM.. Reply below.

Went to IFO in St Louis last weekend. Been having trouble getting parts lately, and couldn't get a new clutch disc for the dogbox (6 speed miata), but I had a new 4 puck for stock input in stock, so I stuck my trusty old synchro trans back in. 90-91 gearset, WSS 4 spider, kaaz front lsd...

Been pretty busy lately, but last fall i finally got around to doing some weight reduction on my car. Seats are a big one, and a light set of seats and mounts are worth like 70lb loss on a 1g over the cloth ones. I finally pulled the trigger on a pair of kirkey series 55 17" seats. Mounting...

These are the high pressure springs with the titanium retainers and the steel spring seats. These are designed to install at 1.440" @97lbs. They can withstand a cam with 0.500" lift at that point, or be shimmed up some if you need more seat pressure. Minimum height over the nose of the cam is...

I have a excellent condition used Evo 1 3/4 gearset with hub/slider. These are the same ratio as evo3 (1.16/0.862)have the large single synchros. Stock is (1.115/0.833). Great for a road race/rally guy, combine with an evo first gear for a close ratio trans.$400 shipped or trade for race...

Been hard at it making chips lately. A couple of local guys are building a pair of duramax powered pull trucks. These are competition only trucks, and make around 13-1400Hp. We run multiple high pressure fuel pumps on these, and there ends up being a ton of fuel lines to tie together. So I...

Hi everyone,I'd like to announce that WSS is now a stocking dealer for Southern Polyurethanes Automotive Coatings! SPI for short manufactures a superior line of primers, clears, and a few select solid colors in base-coat and singe stage (Black, White, Orange, and several shades of Red.I...

Been working on setting up a store section for the website. As a test I have setup a section for the shifter bushings I offer, and am offering a 20% off sale on them for the next week, ends 1/16/19!As for more new products,I am working on a lightweight bolt in driveshaft loop, I have the...

Seen a couple posts on the instalation of balancer shaft bearings, and a couple guys struggling to install them with makeshift tools. So, I decided to design and build a specific tool for the job. This tool pilots the driver in 2 locations while installing either of the front balancer shaft...

I've had a hell of a year, basically only made it to the track a few times. Had a dead fuel pump at the shootout, then broke a trans first pass at my next outing, then next one broke an axle. I've been struggling to get consistent launches for the last few seasons as well. I was pretty well...

Don't let your expensive injectors sit all winter uncared for, send em in and get them cleaned and flow tested so they are ready and waiting for next season! Unlike most injector shops we have the ability to test the injectors at nearly any pulsewidth, and frequency (RPM).We have a couple...

I'm thinking about making a move to full slicks, and I'm planning my moves, but I'm getting hung up on wheels. Anyone got any ideas on some reasonable 15x8 wheels in the +40 to +45 offset area that are not slip streams.

Hey guys over the years I've accumulated quite a bit of experience in rebuilding our W5M33's and such. I figure it's time to share some of this hard earned knowledge and experience and offer transmission service.We can pretty much do anything depending on parts availability, but for those...

In my never ending quest to make my car quicker and more street-able I've spent a ton of time and effort trying various combinations of parts, and other things to make them work. Lately I've been working with an ACT2900/street disc setup, as it really works nice for DD. The problem is they...

I just made a small run of these as a feeler. They are a nice 2 piece design for optimum fastener preload. The outer piece is nice and thick so it won't suck in when you tighten the bolts. They really tighten up the shifter quite a bit. $45 shipped.

So end of last month I was fortunate enough to get to spend an entire day playing on an engine dyno. Ended up making about 15pulls. I have been experimenting with a new engine control system that I wrote the software for, so it was nice to proof that it actually works as expected.I've been...

Recently I built a new harness for my car, and have some extra stuff left over. All of these are quality oem supplier pieces, no Chinese eBay junk. First up, a set of injector connectors these have a wire lock just like the original 1g connectors do, and are somewhat hard to take off, but they...

Not sure if many have seen, tried to take my talon out on drag week. I've had a hell of a summer trying to get the thing to make power. Ended up building a new engine, and swapping back to a stock computer and he351 just days before the shootout. I also put in a liberty face-plated gear...

Stick shift shootout

Over the last few months I've been working on the development of a new stand alone engine controller. Running a large VGT turbo and aiming for 150mph traps, I have different needs than the traditional stand alone user. IE I need to use a maf, and have some way of controlling the VGT. So far...

@donniekak @b00stedtalon2 @familyMAN I can't think of anyone else off had, add them.What are you guys doing for a license at the shootout? Boosted and familyMAN I suspect you guys are good on tech for the ET you'll be running.I think my car is good for 10.0@135, and I'm hoping to see...

Last fall I went through the trouble to modify an EvoIII intake to work on a 6 bolt head, as well as de-tabbed it and made provisions for dual fuel rails. I have been running staged injection on my car since mid 2011 on an intake I made from part of a stock 6 bolt intake. I've long suspected...

Over the last few years, I've been steadily learning more and more about some of the shortcomings of our AWD system. One of the largest sore spots is the center differential. It's an all around bad design, and I can't recall any other differentials that just allow a cross shaft to "free float"...

Here's why you should always insist on a 4 spider center diff that drive off all 4 posts. These pictures depict 500ft*lbs in first gear. One of the baddest steels for this application is 300M, and it has a tensile strength of 270ksi.. So we are well past the endurance limit of almost all...

So I've been tinkering with a Garret AVNT off a big isuzu staight 6 on my talon. I've had it running pretty well and today was my birthday, so the old lady took me to get the shitbox dynoed. Not much for AWD dyno's around so I was stuck on a 2wd Dynojet 248H. Can't say I was very impressed...

Ok, Does anyone out there have a list of mitsubishi differentials? Sort of how like dana makes a D44 D60 D80 ect, Chevy has a 10 bolt 12 bolt.I would like to know what ring and pinions are swap-able to what.I know that we can take a evo ring and pinion and put in a dsm case ect. Is...

Hey guys,Any of you know what IFO is looking at for the compressor inducer limit. They are going to a 63.5mm limit for FIS next year. Are they wanting the OD of the wheel or the ID of the housing? In the past they never looked at anything at all, but I'm doing some custom work on my VNT...

Anyone out there still looking at EGT's I'm looking for a ballpark number for a car making 600whp on E85. Not trying to tune by it or anything, just trying to do some rough calculations on turbine efficiency.

bastarddsm submitted a new DSM Profile :ShitboxRead more about this vehicle here...

Made it to IFO in St Louis Sunday, and finally have the car running decent. I made two easy passes to check the tune since I fixed a few boost leaks, and haven't drove it since the shootout. Then let it eat in the 2nd qualifier, and 2 rounds of eliminations. Pretty solid ET for the MPH, and...

What's the deal with turbine housing vband sizes. Garret specifically. How are they measured? Does each brand have there own proprietary sizes? Where do you buy the parts? My exhaust is all 3" vbands, but I bought them together off ebay so it's been no hassle.I have a .96A/R open t4 Ptrim...

I'm going to be doing a 3kgt rear end swap in my car. I'm looking to see if many other people are looking into putting a 3kgt rear in a 1g. I'm considering building a jig for this so I could crank a few out.

Don't think I posted these anywhere, but I was making a couple test hits in my car. It's dark so you can't see much, but it sounds cool. Nevermind the garbage idle, ICS is junk :(. Stock Block Kelford 272's Kiggly Springs HE351 Turbonetics Manifold Internal gate at 28psi or so. Quartermaster...

So i've had this 90 GGSX for a few years and it drives like shit. I finally got it on an alignment rack and heres what we found. Right Side SAI 17.6* Camber .4* Caster 3.1* Left Side SAI 13.6 Camber -.1* Caster 2.7* The car steers under large suspension movment. As the power comes on...

So I'm fighting an issue with my car and I can't figure it out. Last summer the car was on about 34-35psi ~12:1 AFR gas scale on E85, and basically 19-21* timing. It always trapped 133mph, except for one pass it trapped 137 in the 1/4 and 102-104 in the 1/8. On a dynojet it was making right...

I made a data logger out of an Arduino, and an SD card sheild. I went to the track sunday and pulled off a new PB 10.85@132, and pulled some data with the logger. It definatly shows a text book example of why AGX's are garbage. Didn't have time to get a wheel speed sensor hooked up, but I...

Bought some QTP's, so I drove the car 300mi home from school from break, got 21mpg on E85. Put the QTP's on and went to the track. 3rd pass 10.99@131, 1.77 60'. Next pass popped the Tcase. Trans is junk, and shifts super slow into second. I'm sure it's hurting me by a tenth or so. So...

Over the summer in my quest to find the best clutch for my application, I checked the clamp load of all of the PP's I had in stock.Turns out an OEM mitsu pressure plate is a pretty nice piece. The XTD and Parts store Replacement ones suck. The 2600 does what it claims, but there seems to...

I need the Part number for the early Fiber lined Synchros for both 3rd/4th, and 1st/2nd.

After a bunch of frustrating trips to the track, I figured it's time to take the plunge and get some slicks.GST95 has informed me of M&H Street Strip tires P235/60-15 Seems lots of FWD hondas run them and some Auto guys run them with good results.It looks like I can buys some 15x7's...
