7evin Posted March 23, 2008 Share Posted March 23, 2008 We might have to go with plan B. Hey, how come I don't know about plan B ??? K Link to comment Share on other sites More sharing options...
Mandurath Posted March 23, 2008 Share Posted March 23, 2008 Is plan B extending the hood bulge, or adding a scoop/naca duct or something and mounting the horizontally above and behind the radiator? Seems to be a good gap there, where the scoop would force air through and down through the engine compartment. Pain to plumb with the one you have unless where you got it would exchange.

WestTexasS2K Posted March 23, 2008 Author Share Posted March 23, 2008 I had thought about using something like a WRX intercooler that is mounted on top of the motor then using a scoop. But I really didnt want to change the lines of the car to much. Link to comment Share on other sites More sharing options...
Boxologist Posted March 23, 2008 Share Posted March 23, 2008 maybe find a saab owner for the current intercooler if its a problem. I think a 2nd design could be a larger core(+50%) and have teh endtanks on teh right and left. the tank on teh passengerside for exiting air shoudl be at the top so u can run piping along the top of radiator if possible, or in between teh engine and radiator. i don't remember how much clearance there was in an ultralite around teh radiator.

WestTexasS2K Posted March 23, 2008 Author Share Posted March 23, 2008 The problem is that the hood is 1/4 - 1/2" from the radiator so there is no room to go over the radiator. The radiator cant go any lower either. Now we could move the radiator back which will allow some room over the top but then the fan will not fit. It is tough on these little cars. There just isnt alot of room anywhere. We are going to rename this car to'' It Just Fits BARLEY" Link to comment Share on other sites More sharing options...
Mandurath Posted March 23, 2008 Share Posted March 23, 2008 I do not think it will matter that much, looks like there is enough of an air gap for the radiator to get some air behind those tanks. And other ways, like on top would require cutting the hood. Hehehe Though I think adding that big ol wing has already altered the lines of the car. Lookin good! Looking forward to your write ups on this years runs. Link to comment Share on other sites More sharing options...

There is a dead spot at the center of an electric fan where the motor is. The pressure difference across the radiator needs to be 50 kpa. Hope to see you'all this summer. :7head: Link to comment Share on other sites More sharing options...

7evin Posted March 24, 2008 Share Posted March 24, 2008 Bob, Check out Watson's Street Works. www.watsons-streetworks.com They have some pretty slick stuff Loren is asleep at the moment.

Boxologist Posted March 24, 2008 Share Posted March 24, 2008 http://www.usa7s.com/aspnetforum/upload/757039470_Resized_pics 119.jpg i can see big red X s as brake lights in ur future. just like Family Fued. pressure sensitive switch, so 1, 2 or 3 red Xs go on! :7head: Link to comment Share on other sites More sharing options...

7evin Posted March 25, 2008 Share Posted March 25, 2008 I would love too. I'm making a quick trip down in June. Our racing schedule this year is completely nuts.... It might have to be fall. I am looking for a latching circuit or a mechanical latching relay so I only have to use one push button momentary switch to turn the electric fan on and off. Does anyone have a source? I do not want to use the 4 relay setup. Not enough room in a 7 for banks of relays. I would love to find a solid state unit that has 4 or 5 inputs and outputs. Or relay/mechanical switch. Cheers K Link to comment Share on other sites More sharing options...

Now that would get the attention of any one tail gating you. The possabilities are endless. :) Cheers K Link to comment Share on other sites More sharing options...

If anyone else is looking for something like this check out Pilot 4 button flat panel switch. http://pilotautomotive.com/catalog.html I did not like the looks of the switch setup it came with so I just cut the connector off and solder my own wires on.

WestTexasS2K Posted March 31, 2008 Author Share Posted March 31, 2008 Its alive!! We fired the engine today fixed the usual nagging leaks, bleed the brakes burped the coolant. 7evin loaded the car up at midnight heading to dallas for a 10am dyno session. I guess we will see if all of our hard earned work is going to pay off. 7evin is planning on videoing a few of the runs we will post them when we get it them done. Bed time for now. 7evin has a 5 hour drive ahead of him he should get 3-4 hrs of sleep before the shop opens. Man this is starting to feel like the 1 lap already. 20hrs a day of work and a few ours of shut eye for 7evin for the last 4 weeks. He is going to need a vacation to get over his vacation.

WestTexasS2K Posted April 1, 2008 Author Share Posted April 1, 2008 Well 7evin has been in Dallas at Jotech for the last two days dynoing the new car. (whew I am glad I dont have to pay that ticket) We are very pleased with the results of our supercharger system. It performed just as we had hoped. We experienced no belt slipage and the boost curve is very similiar to a turbo. We start building boost at 2200 rpm verses the old Vortech systems 6000 rpm before we built boost. With the boost building lower our powerband is twice as wide as before. We are set up for two boost levels. On pump gas we are running 9 lbs and we are getting 300hp and over 200 ft/lb of torque. In our E85 Organic Racing mode we are running 13.6 lbs of boost and the results are really impressive. I will just say that it is well north of 300 with a good boost in the torque curve. The nice thing about the E85 is it gives us a very nice cooling effect the engine never got over 180 degrees and the intake temps were very good. We have very conservative tune on the car for some serious track use with no fear of detonation. We also running a little fat giving up about 10 hp to keep it in a safe range. 7evin will be back tonight with the car to finish up the wiring and odds and ends and get the car ready to hit the road for the Hill Country tour. Hopefully in 3-4 days the car should be about done. 7evin took video of the car on the dyno we will post it in the videos section later. Link to comment Share on other sites More sharing options...
7evin Posted April 2, 2008 Share Posted April 2, 2008 Hey Guys, Just got back from Dallas after spending 2 days on the dyno and hanging out with Kenny Tran. For those of you who do not know him, He is the Jet Lei of the import tuner world. Races a 2.4L Scion that runs 60 psi of boost and approx 1200 hp.(8.1 sec @ 181 mph in the 1/4) He doesn't know the exact HP because his dyno can not handle that much HP. Very humble and very bright guy. Kenny working his magic. http://www.usa7s.com/aspnetforum/upload/223995895_pics 022.jpg We are short about 2 psi of what we calculated for the E85 fuel. so we have to hunt for the missing pressure. As a side note, when he finished tuning the car he asked " what does this thing weigh ? " I told him and he looked at me wide eyed and said "WOW this thing is going to be fast! " Then he said I think I might have to get one of these. I warned him that it was not a good idea.... Of course he ask why ? I said you will lay in bed at night thinking about twisty roads that you can't wait to drive it on.... I am going to take him for a ride and close the deal.....
