Looks Great Jason, nice little pop of Flame on the one Dyno run.... :)
LOVE the blue Neon too ;) Chris. |
Car and its stance does look superb! Love the blue wheels :cool:
How does the cooling hold up? 198 whp isn't bad for a start either :D At what rpm was that? |

198 whp isn't bad, but we are hoping for more like 240 whp by upping the boost at all rpm using one of these: http://www.autocarparts.com/images/139/2020_0.jpg I found a decent deal for $460 for it. These are very good boost controllers for the price, featuring a cool programming feature that allows for gear specific boost control. For drag racing, you might need to limit boost till a higher gear to minimize wheel spin, and this thing lets you do that. As I recall it was hitting the max hp at 6600 rpm, and at about 14 psi of boost, Lawrence is hoping to hit and maintain more like 16-18 psi early and holding it using the boost controller. He was surprised we hit almost 130 mph in 4th, apparently I've got a sort of tall gearbox. I totally forgot to mention I've also installed one of these: http://www.3sx.com/store/catalog/aem...00-03-600l.jpg I picked it up from Summit Racing for about $400. We installed an additional injector at the hot side of the IC to maximize the ICs cooling effect, and the larger one in the standard location at the cool side. It works so well that if you run it on test mode, just spraying at lower boost while the engine is running, the IC actully gets cold to the touch. Typically this system is progressive, increasing the volume of Meth sprayed based on boost level. The testing and tuning used about 1/5 of a gallon of Meth, and I installed the tank in the spare tire well so I can inspect the level at each gas fill up. Pics to come on these, sorry. Both of the "ricer" add ons will help the car have more HP and keep a higher margin of safety at the current boost levels AND at the higher boost the GT28RS will produce, so it's a win win. These have been around for years and have proven themselves extensively, funny that I've never seen either in a air or wc VW?! Jason |

I ran and run ~300 WHP at 15 psi with the GT3076R and the same with the even larger turbo now, so I can pretty much assure you your bigger GT28RS will give a lot more hp (I guess your +40hp is very possible), even at the same boost :) A larger intercooler as you have now should go a long way before it saturates with heat. With higher boost levels the water/meth injection helps prevent detonation and makes really high boost levels possible, but more then 22-23 psi with the 28RS will probably bring not much more after that. Maybe log the IAT? |
I've only got the tiny stock KO3s turbo right now, I think the +40 hp with it seems a little high, but I don't underestimate my tuners abilities. He's never blown up a motor and has built the only Supra turbo to run in the 9s in the quarter with stock internals.
With the GT28RS it should make close to 350whp. I just want to keep my spool up rpm/time to a minimum, so the GT28RS is the happy medium I think will be the final setup, just trying to make the most of the stock setup for now. We can watch the manifold air temps, and they have never gone over 120 deg, but again that is with the small turbo, things will get more interesting for coolant temps, air temps, and clutch when the 28RS goes in. I may not "feel the need" after the boost controller is added, we'll have to wait and see. Jason |
Jason, my tests on rear 1/4 window ducts showed flow so poor, with my rads over the trans, they appeared to reverse flow at times, if your street legal you can run good 'tuft tests', also, if your feeding into the cabin, be carefull with high speed internal cabin pressure build up when they may stop flowing suddenly just as you need even more flow, not good, its easily possible to blow a plastic window out with internal pressure, as i had to run tests at night with a mate and a torch in the back as observer, they were a bit limited, but it was life or death for my motor as the ducts feed engine cooling, so i made up guide vanes to turn the air into the ducts, not pretty, but it works, so no worries now..
|
Have you seen this?
http://www.pro-touring.com/showthrea...t=aerodynamics The undertray, spoiler, bonnet vent is a similar issue he had with an old Maxima turbo, no flow across the intercooler and making the radiator work harder. |
I had seen it, but thanks for the input, mostly nobody shows aero in plan, which for rear side window ducts is where we have a huge problem, look at a bug from your first floor window and you will see the 1/4 window problem, and it gets worse at high speed, oval owners will have wondered why semaphores lift right out at 60 mph, at 75 they're right up and wont go any higher, ...
|
I havnt even started testing, want to wait until the roof lip is installed to see if that will create a low pressure area that I can exit the NACAs flow to. Otherwise the air may be flowing backwards as mentioned.

Damn, I wish you were closer to south bay. I've been looking for a couple folks to go in on 2500 sq/ft of shop space, and it's only 1500/mo in the middle of town. It's one of those friends only deals. :P Your setup looks pretty good so far, I'm gonna have to head up there again and check it out :)
|
Will, I just snuck into my wife's warehouse, she's rented 10,000 sq-ft, so I just grabbed a corner. We do need to get together though!
Here's a preview of the new center console. The basis is a road bike carbon fiber handlebar, then I lathed some adapters to lengthen them with aluminum. I'm mocking up the panel now, it will be fiberglass covered in white vinyl, and I'll probably cover the aluminum legs with the same vinyl I used for the roll cage. http://images.thesamba.com/vw/gallery/pix/862747.jpg Jason |
Next step, cardboard template covered with polyester fleece, then bondo'd, shaped, and holes drilled.

Lawrence from LS Fabrication worked his magic again Sat night. Went from 197 to 232 whp by upping the boost. It goes like a scalded monkey now! Scroll down on his facebook page to check out the vids, even got some more fire shooting out the pipes!
LS Fabrication Facebook Page On Dyno Should be fun at Bugorama on Sun, hoping for low 12s. Jason |
One more, just messing around. Another good flame shoot!
You can hear a low rpm knock as I take off from it, we'll be taking a couple of degrees out around 3k. Shootin' Flames Jason |
Great video Jason...boy that thing is fast!
Love the LED's too, they look good. |
Thanks, appreciated.
Well, latest news: After running 13.05 at Bugorama, I found out on the way home that I'd broken something in the tranny. I knew the tranny was the weak spot in my system, but it happened sooner than later. SOOOOO I think I'm going to start from scratch, take the body off of the chassis, buy a Boxster chassis, and do something along the lines of this guy: Bugster I know that big power is possible from aircooled thanks to Wally, but I really want the balance of mid-engine, and buying a salvage Boxster S will be the easiest and most cost effective way of getting a great handling car that looks like a Bug. I'm shooting for lowish miles and running, but I do like the idea of 4-500 hp in a chassis that is predictable, so down the road I may do a VR6 or V8 like Hugo. I just feel like I've come a long way toward my goals, but that I won't get the type of handling I want with the chassis that I have. I might be parting out the chassis I have now, anyone interested in a double wishbone front end like Mendeola only bolt on? Jason |
lol, I remember you talking about it a while back, in for the long haul!!
Rich |
Yeah, I'm a total NUT Rich! Got it coming next Monday hopefully. 2004 Boxster S, 85k miles, totally straight chassis, perfect interior, $7k. Pics to come as the butcher sessions begin!
|
I'm looking forward to this! Is it body damaged?

I've been tempted many times to look into building a bugster myself! Looking forward to seeing you build one first
-Mike |
Oooooh, this is gonna get kool.
|
Just got a text that we are good for this afternoon, so she should be home tonight. Well, honestly, it was body damaged, but not enough that I wouldn't have fixed it. It has a tear in the body panel between the air inlet duct and the edge of the fender on the drivers side where it cut off or was cut off by a semi(large truck/trailer). The wheel lugs tore into the body from there back to the wheel, which was damaged, as well as on of the control links. So, with a new control link, new tire/wheel, and a patch to the quarter panel this would have been just fine, but I couldn't resist $7k and it's exactly what I wanted as far as interior and tranny so it's getting chopped!
Jason |
Good find, can't wait to see some pics. did you find it on copart.com?
|
Got it off a guy selling Porsche engines on Craigslist. Some cool Ukranians to boot! Good guys. Anyhow, I'm going to keep the UBRDUB together and build this one from scratch so I started a new thread for it here:
Oval Ragster Jason |
Glad to hear UBRDUB isn't being sacrificed..
|
Won't be any posts here for awhile, I'm going to get the Ragster into a driver before I get back to the UBRDUB.

A little update: So last Memorial Day weekend I broke the 02J tranny I had in this car. It's been pretty much just sitting there ever since, but about a month ago I decided to get back on this again. I had purchased a 02M 6 speed tranny a couple of years ago in preperation for the 02J breaking, so I took it and the motor down to Griffin Motorwerke to have 1st and 2nd gear shift forks upgraded and a Wavetrac LSD installed. While I'm at it I'm having Integrated Engineering con rods put in. It was supposed to just be the rods, but it turned out I had a small run engine in which odd pistons and rods were used, so I'm getting JE forged pistons as well. For the clutch we are going with a SPEC clutch and lightweight steel flywheel.
https://fbcdn-sphotos-f-a.akamaihd.n...30924634_n.jpg https://fbcdn-sphotos-e-a.akamaihd.n...44188502_n.jpg In preparation for the new tranny, I've had to redu the master/slave setup, and it was not cut and paste. (no surprise here) The new master is plastic and the slave is a circular part that actually surrounds the output shaft. I didn't know what the volumes of either were, so I'm re-creating the stock setup specifically having to utilize the quick connects that come stock. It will be nice when its done, but it's a PIA now. So on the master end, it's required a sleeve to allow the Wilwood pedal engage the new clutch master. My friend Micheal has been amazingly helpful with the odd machine jobs I've had to do and this was no exception. The old VW master had a large enough diameter rod that I was able to just cut threads right into it and utilize it by itself in the pedal assembly. The new plastic master has a smaller diameter shaft, so I needed to build an adapter to retain the use of the pedals. https://fbcdn-sphotos-g-a.akamaihd.n...29286699_n.jpg https://fbcdn-sphotos-c-a.akamaihd.n...97144313_n.jpg https://sphotos-a.xx.fbcdn.net/hphot...06506534_n.jpg https://sphotos-b.xx.fbcdn.net/hphot...18177029_n.jpg https://sphotos-a.xx.fbcdn.net/hphot...25427884_n.jpg |
Oh, thought you might like to see how I get the engine/tranny in and out of this thing!

1.8t Mid-Engine 1960 UBRDUB
Love this car, its very unique,some out of the box stuff going on here, congratulations very cool.
|
I agree! Fantastic build with a huge amount of potential! And it looks awesome too!
|
Coming back together. Ordered custom axles from Frank at Driveshaft Shop. Got the new hydraulic clutch line rebuilt and ready.
https://sphotos-a.xx.fbcdn.net/hphot...23790922_n.jpg New clutch master installed in the old space, not cut and past unfortunately... https://fbcdn-sphotos-c-a.akamaihd.n...61881976_n.jpg https://sphotos-a.xx.fbcdn.net/hphot...86365097_n.jpg Ordered Corrado 5x100 hubs and have already recieved 5x100 -> 5x130 adaptors. I'll put my energy into The Ragster until the axles arrive. Jason |
Santa is making an early round:

Nice bits!!
|
Is this car still getting any love?
|
It's getting love in my mind, but not really. It has been on the back burner till I can get the Boxster/bug off of the lift. The lift is smack dab in the middle of my wife's handicap vehicle business, so I'm really being an ahole being on the lift as long as I have already. Soon as they are both back in my little corner of the shop I may work on it again, but really I just can't wait to get the Bugster started up, so that might still be a priority!
Jason |
Finally did a little work on the UBRDUB. One of the steps involved in putting the new tranny in was to replace the recycled steering rack with a dedicated part.
