Someone at the hillclimb is building an old formula J open wheeler for hillclimb with a 2.0 Subi single cam engine with a 471 blower with mech injection running Alcohol. It stands twice the height of the car:thumb
One of the crazy guys that currently drives a alcohol Hyabusa powered go cart.

Weaseling out of things is what separates us from the animals....................Except the Weasel.
Can I run both , I would like to know ?
I have the turbo that bolts on easy ( stock ) the blower would just T into the same line , may be a PRV in the line

Many years ago Bill Oakey built a Drag Race motor that was both Turbo'd and Supercharged and ran on Methanol. It was a Keith Black Hemi with four (I think) turbos piped into a GM Blower. I can't remember the size of the blower. Reports at the time said it had similar power to a Nitro motor but he couldn't find Turbos that would last. Seems the exhaust pressure was too great for the impellors and they kept failing. I don't think he ever managed a full pass, the Turbos would fail on the step of the throttle. Actually there was/is a Torana doing the rounds of the car shows that is both Turbo'd/Supercharged, complicated looking plumbing!
there was a 13bT mazda 323 in Zoom last year with both blower and turbo. he ran a valve of some sort in between the two. Apparently it was really good and not that hard to do. One of the Jap performance houses also made a similar setup for early MR2s.
2.5 with a VF34 why botha.Over rated. TD05 witha 18 or 20g wheel mods now thats the way to go:thumb.....Blower waste of time.A 2L can out power a 2.5 with the right mods.Now a EJ22 would be interesting witha blower:thumb JVL
The Vf34 is one of the best/cheapest power up options on the market. Because you can buy it for $1300, it is ballbearing and has the same exhaust wheel as my 24 with a bigger compressor for more boost and cfm. In mine now it is like it doesnt have a turbo...it spools up so early and hard. For the street and track it is awesome.
A TD05 is great for high flow/strenght,even with a different exhaust wheel...will not spool up as quick as a vf24/vf34..different bearings and amount of blades on wheels. Both awesome for different intentions.
What compressor and exhaust wheels has your TDO5 have and so people understand what we are talking about, how have the changes you made, such as different wheels altered spool up, response and flow from a stock TDO5.

:thumbFor a start,. Needle bearings are the better way togo......eg. cases are stronger and are firm around the needle bearing its self.The needle bearing runs a greater area surface which keeps it reliable to it s playing surface ..Ball bearings will not cope with over boost where the turbo is working to hard.To many people rely to heavy on the turbo instead of the breathing.......As mention above he runs a bigger compressor for boost from a VF34:P My TD05 runs a modfied wastegate which will run 14 to 16psi reliable without a 16,18 and 20g wheel.These wheels are upgrades for a TD05 for better spool up higher psi.JVL
well the super charger has got to me and I purchased a ej22 that needs a set of rings .
I will be fitting the motor to my gear box with one of my seagull adapter plates & fly wheels .
But before I do this will strip the motor down and rebuild it , timing belt & water pump aside the motor rebuild kit is 15% more than VW .The cost of maching the crank is 7% more than a vw unit , sizing rods ect is the same cost as vw
This brings me to what compression I need for a build up .as for the super charger I doing more home work on as to get the best out of the set up
I going to make a inlet like Christains with cutting to units one high & one low then weld them together .
I keep you posted , with some photos .

EJ engines came out with two different big end sizes the NA 20's 22's and 25's all had 48mm big ends until 1999 then they went to the stronger 52mm in the ej25,WRX run the 52mm big end crank,for forced induction i would highly recomend the 52mm big end crank from a WRX or post 99 ej25 to prevent spinning a bearing.
JVL....whats modified on your wastegate...my vf24 runs runs 16 psi all day. The more expensive, better performing turbos are ball bearing..they spool up quicker and can spin harder with less friction. Vf30....same as a vf34 without ball bearings spools up 500rpm slower and is $400 less.:thumb:P:thumb
The 16g, 18 and 20g wheels are all smaller than the 22 on the t5..none will pump harder than a stock 22g top end. As the size gets smaller, the ability to spool up gets earlier but run out of puff a little earlier also.👍👎👍❓
Sorry seagull...I would love to have a supercharger after the turbo....amy pics.😉

Hi Craig, have you comenced your wrx project yet??
Hurry up and get yours on the track JVL, I want to see it run. Craig may have one out there before you if your not careful!😘sandrine😘thumb:thumb😘
I had a good look at Christains ej22 super charger today and I was blown away with the quality of this set up .
I can wait untill he fits it and we can go for a test drive .I think it will end up in my shed as to change the belt drive to a clutch set up from a car air con .
I let the digital cam at home , so mate can you put up some photos , seagull

Its all happening Boof going the fastest as i can.Business work commitments waiting waiting for parts.....:Poh! Craig doing a subie!!!!hahahaha:P:P:PJVL

Just to answer your quest Matt spill a little of the beans....Mods on wastegate ported and lever-arm mods.....TD05 is my way to go:thumbJVL
Just set up a new workshop...we have all the crazy metal fabrication tools and machines. What do you want made...2 things I will gaurantee:
1. It will work like it should..if not better.
2. You will get the parts if you pay for them.
oh and a 3rd...quickly.
JVL, did you just clean off the carbon with a dremmel and bend the wastegate arm so it holds higher psi.
