ivans imports Posted August 16, 2012 Author Share Posted August 16, 2012 so i rebuilt my toyota 4 piston calipers and moved the peadal ratio and put on a smaller master to help hold it back at stall it only has rear brakes so now i can hold it at the line at 3500 rpm stall is all the brakes can do to hold it back it gets angry the front lifts right up and the back drops almost to the ground jumps out of the hole was getting it to pull the front wheels off the ground on the tests in front of my house see how she do's thiss weekend Link to comment Share on other sites More sharing options...
Uberoo Posted August 18, 2012 Share Posted August 18, 2012 maybe run less nitrous and more turbo boost? Link to comment Share on other sites More sharing options...
ivans imports Posted August 21, 2012 Author Share Posted August 21, 2012 we dialed the nos down to a 50 shot was making good times untill got boged down and loaded when got loaded the # 1 piston cracked and pices got on top of # 3 and smashed plug changed plug and she still ran but has piston damage agian so the delma is how to get anuther 300 hp out of what i have the cars in my class are making around 500-1000 hp and for me to get on top i need at least 400-600 hp right now i'm 300 at best need some ideas on what to do next lighter longer more hp i have my lanch perfect traction is perfect suspention is good just need more motor or managment anyone whant to sponser me a race motor Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 21, 2012 Share Posted August 21, 2012 Don't know if you're running water/methanol injection as well, but if you're cracking pistons from detonation you should be. It works miracles at suppressing knock. Link to comment Share on other sites More sharing options...
ivans imports Posted August 21, 2012 Author Share Posted August 21, 2012 is one of the next steps we are looking at any ideas for a kit for subarus and how whould it mix with nos ? Link to comment Share on other sites More sharing options...
ivans imports Posted August 25, 2012 Author Share Posted August 25, 2012 So thiss is the ten year power plant list for buggy started with a ea81 carbed whent to ea81 turbo with Su draw through then whet to 2.2 na engine with turbo then a 2.2 turbo engine with twin cam heads then a 2.5 with roller 2.2 heads turbo then a 2.7 xt six with turbo then a 3.0 six with turbo then a 2.5 with twincam heads and turbo then back to 2.5 with 2.2 turbo heads and finaly a 2.5 with forged turbo pistons and 2.5 shoc heads that i a'm running now anyway have broken the pistons in evryone of theese engines even without nos on every one the pistons were the only problem with them nothing esle ever fails just pistons Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 25, 2012 Share Posted August 25, 2012 (edited) Did the carbed ea81 break the pistons too or just all the boosted motors? Running lean and running to much ignition advance on too low octane fuel causes busted pistons. Water/meth can help with that for cheap and be used with nitrous. Spray it in the outlet of the intercooler so that it has time to be fully dispersed by the time it hits the throttle body and intake plenum. Or do port injection, one jet in each intake runner. More likely to clog though because you're running 4 tiny jets instead of one big one. Start playing with water/meth and you'll be surprised how much power you can make for dirt cheap. I use -20 or -30 winter grade blue windshield washer fluid. 9.6:1 compression, 12.5psi out of a non-intercooled roots supercharger and no tune. Runs on premium pump gas. Stock engine with forged nothing. Edited August 25, 2012 by WoodsWagon Link to comment Share on other sites More sharing options...
maozebong Posted August 28, 2012 Share Posted August 28, 2012 (edited) yeah, i agree. you sound like you should be making more power with your current setup with proper engine management... and you also sound like you are having serious detonation issues. ive seen much more power put out of those motors than 300hp and when they failed, it was never pistons breaking or burning up, maybe a loss in ring seal, but never breakage. maybe a real dyno tune on an AEM standalone, meth/water injection kit, and a redundant fuel pump for the nitrous on a wet 100 shot (fuel and nos), and possibly an intercooler if you dont have one already. the best part about real engine management is that the nitrous and fuel and meth/water sprayer solenoids can all be controlled by the ecu, and safeguards can be put in place to curb detonation via knock sensors and AFR monitoring.

ivans imports Posted August 28, 2012 Author Share Posted August 28, 2012 the ea81 su carbed turbo was the lightest and simplest and made good times butt pistons broke was a neat setup realy simple. anyway i have the water meth setup puting it on today it whould be nice to have a stand alone feul seyestem but have no supplyers here for that just lordco and min 1200$ for engine management my ecu and harness is from a 91 legacy 2.2 five speed i know its not the best for turbo but is the simplest one i use no intercooler because it turns into a bomb have had some nasty intercooler blowups I a'm cocerned about the nos turning the water meth to ice and could that hurt the engine anyway have 3 days to get ready and race took 25 lbs off the tires and almost 200 lbs off buggy hope lighter is faster Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 28, 2012 Share Posted August 28, 2012 Don't have them spraying in the same spot. Put the water/meth jet right at the turbo outlet and the nitrous by the throttle body. That will give more time for the water to vaporize and suck the heat out of the compressed air. Link to comment Share on other sites More sharing options...
maozebong Posted August 29, 2012 Share Posted August 29, 2012 why not look into a universal EMS. you are most certainly competent enough to run the universal wiring set, configure the various sensors to the EMS, and it could be reconfigured to every engine setup you would ever want to run, even if you changed to 6 or 8 cyl.

ivans imports Posted August 29, 2012 Author Share Posted August 29, 2012 i whould like a good stand alone injecton seystem but not in budjet for thiss year i managed to remove alot of weight have been weighing the removed materail to get idea of total weight removed is slowly ading up i will put the water sprayer in but only have a spot right in front of or behind the nos sprayer is very short pipe from turbo to tb and not mutch room for jets hope it dosent cause problem i wish had a test track for it hard to get it into the boost trying it up my road dyno whoud be nice Link to comment Share on other sites More sharing options...
ivans imports Posted August 30, 2012 Author Share Posted August 30, 2012 put in the methanoll kit and tested it but have not tried it yet I cut my tires so mutch that dont whant to run it on pavment for fear of hurting cut tires have a nice hook to them now keep them sharp for race anyway off to the races hope it works good for me Link to comment Share on other sites More sharing options...
WoodsWagon Posted September 1, 2012 Share Posted September 1, 2012 So how did it work? What size nozzle did you run on the water/meth? Link to comment Share on other sites More sharing options...
ivans imports Posted September 4, 2012 Author Share Posted September 4, 2012 It worked unreal made hudge power did a 39 second run at rev limiter full nos and a # 3 water meth sprayer was night and day the pitts were very deep was deeper than my wheels i beat the 454 and the 440 but couldent catch the 517 or the 383 both over 900 hp came in 3rd in B class makes me 3rd over all was crazy to see how mutch diferance the water meth made I'm a beliver now the buggy engine never ran like that before every run was long and had to realy work the engine but came home running on all 4 and smother and more vacume than ever water meth makes me very happy even without the nos on is a noticabble differance probly 10-15 % more before the nos was defanatnly making more power !

WoodsWagon Posted September 4, 2012 Share Posted September 4, 2012 That's great to hear! Yeah, it's one of those things you don't think will work until you try it and find out how well it does. Just make sure to keep the system clean, you don't want dirt clogging the nozzle. Link to comment Share on other sites More sharing options...
ivans imports Posted September 5, 2012 Author Share Posted September 5, 2012 makes me wonder what the 3.0 turbo whould run like with water methanol Link to comment Share on other sites More sharing options...
WoodsWagon Posted September 5, 2012 Share Posted September 5, 2012 Might as well see how high you can take the 4cyl before switching to the 6. More boost, more nitrous, more fuel and more water/meth until it spits a rod out of the block. Link to comment Share on other sites More sharing options...
ivans imports Posted September 6, 2012 Author Share Posted September 6, 2012 well race seasons over so no need to be nice to it anymore i cant wait to take it out in snow for a play or back to the beach in burton i dont know if my little wrx turbo can boost more than 15 psi but can try and have a #5 jet for water meth and a # 28 for nos and a # 38 for feul should make for fun playing one of my rear air struts is blown and the rear wheel is bent out 3 inchs from deep hole contest so some repairs are in order but got in every single pass all season no dnfs and still has all 4 cly Link to comment Share on other sites More sharing options...
