Garrett76Zt Posted March 19, 2008 Share Posted March 19, 2008 I'll have to look again at my temps. Should I have the IAT sensor after the meth nozzle? As far as nozzle size, I don't know. I bought the kit used off e-bay and other things keep me from remembering to order a correct size nozzle. I know its dumb of me. As of now the meth nozzle is after my IAT sensor. The meth comes on full strength at 14lbs, I have no controller. Just a boost switch. Well I've seen people do it both ways, before or after the meth nozzle. I have my IAT mounted in my intake manifold so it shows me what kind of affect the meth is having on temps(lol it also shows me just how much heat soak i get when i turn the car off at the gas station!) Only you have to be careful not to place the IAT to close to the meth nozzle, I was getting some error codes because the meth was spraying directly on the sensor so make sure its downstream a ways. So you're saying your meth is not progressive based on manifold pressure? No progressive controller? Quote Link to comment Share on other sites More sharing options...
CantZme Posted March 19, 2008 Share Posted March 19, 2008 my guess is 375whp 400wtq, but I guess on it depends on what dyno is used. Quote Link to comment Share on other sites More sharing options...
Gollum Posted March 19, 2008 Share Posted March 19, 2008 I'm gonna guess 382 for the first pull. After that all bets are off till he blows the motor up. I'm sure he'll hit 400 unless he blows something. Quote Link to comment Share on other sites More sharing options...
Globerunner513 Posted March 19, 2008 Share Posted March 19, 2008 Is it a Dyno-Jet? or? I'm gonna be the odd ball and say 330rwhp. That'd still be about a 400hp motor I would imagine. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted March 19, 2008 Share Posted March 19, 2008 I guess 365rwhp depending on temps Quote Link to comment Share on other sites More sharing options...

Careless Posted March 19, 2008 Share Posted March 19, 2008 prox got my guess, so I'm going with 325, just cause. Quote Link to comment Share on other sites More sharing options...
myplasticegg Posted March 20, 2008 Share Posted March 20, 2008 just an adjustable boost switch I set to 14lbs. Throw it on an extra channel of MS? The boost switches are great unless you want a good tune with the meth. Lean, leaner, leanest, (Meth/14psi) RICH!, less rich, happy. Might be worth looking into. shane Quote Link to comment Share on other sites More sharing options...
firm Posted March 20, 2008 Share Posted March 20, 2008 I'm not sure what it is? If I'm not mistaken Alamo has a DynoJet. I had a couple of friends dyno and tune out there a while back. I'm all kinds of stoked for this weekend.. I'm rooting for the 400 mark for sure, that would be all kinds of awesome. Quote Link to comment Share on other sites More sharing options...
Bernardd Posted March 20, 2008 Share Posted March 20, 2008 Phil, what is your dutycycle during a boosted run? Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted March 21, 2008 Share Posted March 21, 2008 hey Phil.. any chance you can post up a shot of your fuel/spark map after tuning?! hell even a MSQ file would be awesome! Quote Link to comment Share on other sites More sharing options...
240zV8 Posted March 22, 2008 Share Posted March 22, 2008 im gonna say 650rwhp, thats with the elvis costume in full effect Quote Link to comment Share on other sites More sharing options...
S30TRBO Posted March 22, 2008 Share Posted March 22, 2008 My guess is 365 rwhp prove me wrong BP. Good luck, standing by for a full report.... Quote Link to comment Share on other sites More sharing options...

proxlamus© Posted March 22, 2008 Share Posted March 22, 2008 Phil I noticed the Max RPM was 5,500 RPM! Umm.. keep going! Isnt that the peak torque number in the RPM range?! Quote Link to comment Share on other sites More sharing options...
jgkurz Posted March 22, 2008 Share Posted March 22, 2008 Phil I noticed the Max RPM was 5,500 RPM! Umm.. keep going! Isnt that the peak torque number in the RPM range?! It's been my experience that the L28 intake and heads just don't make HP much past 5500rpm without significant porting. I've seen this demonstrated on the dyno with my engine other similar setups. TimZ and JeffP both make peak power well past 5500rpm but it took a huge amount of intake and cyl head port work to get there. For me, a larger cam didn't move the power band up either. Peak torque is typically at 4200 - 4500rpm. When doing a dyno pull I believe you should definitely run the rpm's well past peak so you can fully understand the characteristics of the engine through the whole RPM range. Just my .02C.

ktm Posted March 22, 2008 Share Posted March 22, 2008 Peak torque is typically at 4200 - 4500rpm. This is where my peak torque developed as well. Stock P90a head, stock cam, stock N-42 intake. Quote Link to comment Share on other sites More sharing options...
