powderbrake Posted September 19, 2010 Share Posted September 19, 2010 That engine compartment is a new definition of "FULL". Link to comment Share on other sites More sharing options...
WestTexasS2K Posted September 19, 2010 Author Share Posted September 19, 2010 Naah Jerry you can put a whole box of toothpicks in there if you like. Of course you might have to take them out of the box and spread them around a little bit to get them to fit. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted September 20, 2010 Author Share Posted September 20, 2010 (edited) ITS ALIVE!!! Mojito is finally breathing again. After a almost 2 years of engine building, a complete makeover of the intercooler system and addition of a dry sump oiling system Mojito is ready to go, almost. We still need to take it to the tuning mystro Kenny Tran in Dallas for a fresh tune on the ECU. It should be fairly close from our previous tune, but with the compression ratio changes and more air being sucked thru the engine with increased boost we want to make sure that it is spot on before we begin to hammer on her. The dry sump system appears to be working great. We have good oil pressure 30 psi at idle and 80 psi in the upper rpm range which is perfect for the Vtec Honda engine. Of course we were not able to accomplish this on our own. Thanks to Chuck Spera helping us sort out the dry sump system. Chuck was the first guy in the Ultralite community to dry sump his car and his tips saved us time and money. Thanks to folks here at USA7s for moral support and suggestions. Your input is welcomed and encouraged now and in the future. Kenny Tran did the engine build and does the tuning for us. Kenny has been in the import drag racing and car tuning business for years and has been great to work with. Kenny owns Jotech Motorsports if you need a engine build or special tuning give him a call http://www.jotechracing.com/ . Keith and Bryan Cox from http://www.kandbstreetrodsandmusclecars.com/ have been instrumental in getting this car back on the road. Im not sure it would have been possible without Keiths knowledge and fabrication skills to get the car done. With the tight confines of the 7 engine compartment pretty much everything had to be custom built to fit in the engine bay. Keith made the bracket that the supercharger bolts to on the oil pan. Keith made the bracket that the dry sump pump mounts to. Keith made the header to clear the dry sump. Keith made new motor mounts. Keith made the dry sump oil tank to fit in the car. Keith made the air box to wrap around the massive water to air intercooler that I think is big enough for an eighteen wheeler. Keith moved the outlets on the radiator so there was enough room to mount the airbox. So as you can see Keith has had a big hand in getting this car together. Im pretty sure it wouldnt have come out this nice if he hadnt helped us out. Thanks to Doc Harmony for paying for it!!!!!!!!!!!!!!!!!! Here are a few pics of the finished lay out. As you can see the term "it fits just barely" applies to almost every aspect of this car. Edited September 20, 2010 by WestTexasS2K Link to comment Share on other sites More sharing options...

7evin Posted September 22, 2010 Share Posted September 22, 2010 Look forward to seeing the dynochart... and best of luck in Henderson! Loren should have those with in the next week. We are looking for missing children again this year. 2008 34 kids were found because of the efforts of this event. I will post on the off topic if anyone wants to follow along. thanks Link to comment Share on other sites More sharing options...

Mondo Posted September 23, 2010 Share Posted September 23, 2010 While in Henderson, don't know if you gamble... but if you want to blow a couple grand of your winnings (could prepare you for those high speed runs too): http://www.xperiencedays.com/Indy_Car__Victory_Lane.html Link to comment Share on other sites More sharing options...
7evin Posted September 23, 2010 Share Posted September 23, 2010 I don't gamble... But I would love to do this.... I will be on that road course on Friday competing against everyone else with our Tow vehicle (Big Bertha) 2002 7.3L Excursion.... no rental cars this year...

Mondo Posted September 25, 2010 Share Posted September 25, 2010 Kevin, I was thinking about high speeds in the 7 and thought perhaps you should add some caster to your alignment. It would make the steering a little heavier but it would be more stable and less "twitchy" at the high speeds your looking at doing. I'm no expert but you might ask someone who is and get their opinion. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted September 25, 2010 Author Share Posted September 25, 2010 We already have 6 degrees of caster in the car. We are doing another alignment before to tweek the toe to 0 front and rear we will check the caster again. Thanks for the suggestion. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted October 2, 2010 Author Share Posted October 2, 2010 Dyno session didnt go as planned. We ended up with subpar dyno numbers. We were only able to 9 psi out of the supercharger about 12psi from what we want. It appears the supercharger is slipping in the drive section. Rotrex is going to send us a new supercharger larger than the one we currently are using and we will do some testing with it. With the 9 psi we made a 338 rwhp a few hundred short of the goal. Back to drawing board I guess. Dry sump system worked like a champ though. Oil pressure was great from start to finish no leaks anywhere so that is good news. Just need to double up the cfm and I think we will be in the ball park. Link to comment Share on other sites More sharing options...

Mondo Posted October 3, 2010 Share Posted October 3, 2010 So now you got to squeeze in a larger supercharger... hope you have the room. Glad to hear no leaks and everything else seems to be working as planned. I'm sure you'll get it dialed in soon. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted October 3, 2010 Author Share Posted October 3, 2010 Mondo the physical dimension is the same it should be a remove and replace. It just has a different compressor section. Link to comment Share on other sites More sharing options...
WestTexasS2K Posted October 22, 2010 Author Share Posted October 22, 2010 We made 20lbs of boost with the new supercharger. This gave us about 90hp gain over the other supercharger. We have run out fuel pump capacity though and cant pull to 9500, we start to loose fuel pressure at 8900. The tuner thinks we have another 30hp or more in there but we need to upgrade pump. Those 4x1000 cc injectors will move alot of E85 more than the fuel pump can supply. So we are going to have to run the Texas Mile short on hp. Kevin and his family/friends have busted their humps to get ready for this event. I am proud at how much they have accomplised in such a short period of time . Mojito is still a monster and has a huge flat torque curve. Racing starts 8 am on Saturday. Wish us luck! Link to comment Share on other sites More sharing options...
Kitcat Posted October 22, 2010 Share Posted October 22, 2010 Good luck at the T-mile! Keep us posted. Mike Link to comment Share on other sites More sharing options...
Mondo Posted October 23, 2010 Share Posted October 23, 2010 (edited) Well stock is about 1hp to 7 pounds; it looks like your at about 1 to 3... it might go fast;) Look forward to the results Edited October 23, 2010 by Mondo Link to comment Share on other sites More sharing options...
