Time to put on a new set of tires. As Nick's number one mechanic Vasilis works on all kinds of great rides that belong to Nick's customers, friends, and family. He works hard and loves to learn everything he can from Nick's decades of experience with powerful engines. But today, after work, he's going to put some time into his own bad-ass f-body Camaro. This IROC has a little something extra hidden under that bulging hood. An LS1 engine from one of Nick's brother's old race cars Are you going to fix your oil pan now? It's about time. You can take it out now, the motor, Vasilis. A couple of hours and you will have it out. Yeah. Take off the brake, everything you've got, let's go. Since he has to take the engine out to fix a cracked oil pan... he's going to put it on the dyno once it's fixed. And since he recently installed a nitrous kit... he's decided to do back-to-back pulls, with and without the bottle, and compare the results. we're going to take out the engine from his car repair the cracked oil pan, and the put it straight on the dyno and then we are going to shoot it with nitrous and see what it really does . You are going to push the button I'll pull the throttle. That's it. Waddaya say? I cant wait to see it go, buddy. Vasilis knows what can happen to an engine when it is given too much nitrous. or when the bottle isn't used correctly He's seen the result's in Nick's shop again and again. But after working late to pull his engine out last week, and doing shifts at his second job, he's right back to work on his LS1 tonight. He doesn't want to take any of Nick's shop time, so he is staying late on a Saturday night to take a customer's engine off the dyno and get his big Chevy ready for testing. The LS1's oil pan has been reshaped just enough to give it the clearance it needs and seal up the crack while hopefully not interfering with the oil pick up. To the engine! Let's push it on... to the dyno! Vasilis has been going at it for hours. But he knows what a fantastic opportunity it is for him to have his engine on Nick's dyno. so he stays past 3 in the morning getting the carburetor and headers on and hooking up the plumbing and electrical. By Sunday morning, the LS1 looks almost ready to roar once again. Vasilis knows his stuff. but there are a couple of things he could really use a had with as he hooks up his mill to Nick's dyno, he's got way too much respect for Nick than to call him at home on a Sunday. But lucky for him, Nick happens to drop by the shop and wants to see what his apprentice has been up to. C'mon. Let's see what you got. Let's see what you got here, man. You worked all night on it? Yeah. You threw out the 400? yeah. Atta boy. Yeah, I'm not sure about the plumbing here, the way i did it. For the nitrous? For the fuel. You can not make any mistakes. No. But, you see... Here, you got to work off here. This one. That one, I figured. I put the fuel pump on and there was no pressure. No, you have a second pump to plug in. Nick shows Vasilis how to hook up his fuel regulators to the dyno's fuel pump, so that they can run a setup just like it will be in the car. but then, Nick see's something he doesn't like I thought it was going to fit, but the automatic is cut underneath. Oh my god, this is... I know, I dont have an LS set of headers. This is going to be an issue here now. Yeah, your exaust. You're going to loose power here now It's going to right into the tube, facing flat on it. Vasili's custom headers work great in his car. but they don't mate up to the dyno very nicely at all. Luckily, Nick had another set of LS headers in the back of a storage room. He always seems to be able to come up with the right part at the right time.. even for a Chevy. See, for dyno testing, I don't use exhaust manifold gaskets, or header gaskets because it is a temporary use, and it does the job. so we dont waste any gaskets for nothing it dies the job and holds up in the car anyway. Even in the car i have it like that. That's right, and it does the job. As long as the surface is super clean, the job's going to be perfect. Why are you doing it? to see if you really get 150 horsepower? from a 150 shot? Yeah, yup. We are going to see. We'll find out. Nick helps his apprentice get a few last details sorted out before it is time to crank the LS over i got the water pump. fire. There was a backfire. Do you see it now? no. you out the oil pressure? yeah. apart from a flash of flame on the first start up, the old racer seems to be running fine. Here it is sunday afternoon, Im heading back home. to see my family. I've got Vasislis here working on his engine, I think he knows what to do right now. he's going to run a few tests on his motor hes got a lot of energy, he was up late last night putting the engine on the dyno and we got it running today we are going to try some nitrous oxide tomorrow, and after that he wants to put it back in the car. Nick see's a little of himself in his mechanic. Vasilis has the same passion for powerful cars and performance that drives both of them This passion has helped Nick to build a business that caters to some of the best muscle cars in the city. And tonight, they are going to put in a few extra hours to see what happens when Vasilis' LS1 get's a shot of nitrous on the dyno. I'm nervous, more than anything. Well, you wanted to do it, we are doing it. I think i changed my mind. I think i changed my mind. we have an LS1 motor here, that belongs to my my mechanic, my right hand guy here at the shop he wants to try his engine on the dyno, we are going to start naturally aspirated, to see what it makes, and then we are going to give it a shot of nitrous for 150 horsepower, so we'll see what the results are. this is going to be very interesting. Right Vasilis? Yeah, you sure you want to do this? Yeah! Ok let's make a test without the nitrous, and then back to back with nitrous. OK! You ready? Yeah. Let's go for it. And this is belt driven. We are running a belt on power steering, alternator, water pump, and a tensioner ok, we are going to warm it up this way.. ok show me what we got ok, there we go Naturally aspirated, and with the belt on this LS1 is making 513.8 foot pounds of torque and a very respectable 547.5 horsepower everything seems good the way it is... now pick up the bottle and bring it here. ok let's go Vasilis has been looking forward to this moment for a long time it will be his first experience spraying an engine with nitrous but Nick has been down this road before and he's got the stories to prove it Actually, we did a 340 engine we uh, made a few runs , and then my customer decided to put on a 150 shot of nitrous oxide. It went well, we pulled out about 135 horsepower, then he decided to do a 250 shot... and... after we pressed that button, we blew out the dipstick, and both head gaskets. Dont tell me that! So my customer knew it was a 150 shot maximum. so, let's see what this one can do. I hope we dont blow the dipstick... and right now we have a full shop we have no time to start playing with engines, especially when this one is running good. Awesome! Awesome. The most important thing is that we have fuel. but if i see 15 or 14 do i hold it? or do i let go? you are going to let go... you let go dont forget, we are adding fuel at the same time as the nitrous Oh man... here, let's go on idle and just press one shot. on idle, ok? this was all his idea but now that the moment is at hand Vasilis is a little bit nervous It's like... argh. everything is going to happen so fast. you have to react, like super, half the time, you know? ok, are you ready? ok, go ahead watch this. all we are going to do is press this button and get an instant 150 horsepower oh my god! here goes. that is what Vasilis wants to do, that is what we are going to do. watch this.... (engine revs) see that? see that look at this look at the air fuel ratio, it ran rich see? watch this now, we got idle at 900 we are going to activate the nitrous just by the push of a button a 150 shot are you ready? yeah... watch that... whoa ha ha! wow! it ran pretty rich there buddy, hah it ran rich? it went to 9 are you ready? but.,. what if i see it go lean? it is going to go fast... are you ready? but but.. I .. Dont forget you have multi layer head gaskets.. better than the 340. ok? here we go. the water is done? yeah it is done, ok what are we at 6500? 6500. k ok, go to 6600. you ready? ok, do it. here we go. ok. either we make it or break it. yeah. 12.6 12.8. phew. i think i let go a bit early why? because it was #$%ing scary! let's see what our magic numbers are. save current test... ok... it should make no power... I didnt see it go lean.. dont worry about it wow. haha! oh my god! Almost at almsot at 700 horsepower . take a look at this. 691. hahaha jeez at 6000 rpm. yes sir! it's still running good. 691. yo, that is sick. alright , print that. there you go. check it out! 691 . oh man!!! almost 700 horsepower, so how much did we make? 145 horsepower! check it out. 145. there you go. that was something, eh? what the hell?? well, folks. there you have it, we pulled out 145 horsepower. we got to get... 10 horsepower more not.. got to get to 700 this is a 150 shot, what else you got? I have a 200 shot after that. wanna try it? does anyone want to bet what Vasilis' answer is going to be? round two!! guys like this are never satisfied with mind blowing power. They are always going to be looking for just a few more horses. lets go. lets see if it can take a 200 shot. a 12 year old engine what you think? is it going to do it? yeah. it went smooth at 150 let's go man, 200, let's go. In my head, I had explosions. everything went well, we checked the (O2) plug readings, it went well. the air fuel ratio was good. so 150 was safe, we are going to try a 200! Vasili's really happy to see his girlfriend arrive in time for this next pull. Almost as happy as he is to see that his spark plugs are still intact after that first pull on nitrous brand new Do hold it all the way? When ever you are ready, for the whole run. I'm going to let go right before you. but the dyno is holding it back even tho i'm pressing this. Yeah. I don't want to put a load on your engine. You ready? Go for it, go. Now! yes! I saw it. Sick! I let it go at 6500 and it was 12.8 12.9 i saw it this is crazy man hahahaha how was everything else? pretty good? Oil pressure is good, vacuum is good 730! HAH! we did it. Yes! we did it. That's it. we did it! Done. Oh, nman. 730 730 at 5800 the same RPM there we go. let's see the torque reading look at the torque. a 12 year old motor! 752 torque at 4300. Daaaaaaamn. I feel exhausted. Vasilis put in lots of work, getting his engine fixed and then testing the new nitrous kit and the results are impressive he keeps on working hard, and the next weekend when he's got the engine back into his IROC the results... ... are undeniable. Now that is a smoke show! Wooo whoa, you burned the road. Was it good? You are the king. You are the king. Hahahah. Wow! This is what happens, when you go to Nick's Garage!
