C5 Corvette Dyno Testing (A&A Supercharged/3 Pulls at Moh's Performance, MN)

[@lylevaltz9307]

Awesome video & thank you for how much valuable information you put out regarding C5's. How many pounds of boost for the 580hp run?

[@Toys4Life]

Thank you, that's pretty close to 13psi at 6500 RPM.

[@lylevaltz9307]

@@Toys4Life incredible. I have a buddy with a beautifully built and tuned 350Z, and it does similar horsepower number but not until 20+ psi. Pretty beautiful and underrated platform in the C5, and the fact they can produce so much power at relatively low boost is so awesome. Fun to think you could run 5-8psi kind of indefinitely and be in the mid/high 400’s.

Awsome 👍🏼 long tube headers will bring you over the 600whp . Headers allows you to get the heat out of your engine faster. Great video! I'm running longtube and 3.6 pulley and making 651whp for a year now and no issues.

I was told headers are bad for the motor? That they actually make the motor too hot. No? Was thinking about getting one and doing an NA build.

[@Toys4Life]

@@Audfile I don't think they're bad for the motor, but they do create more underhood temperature heat and if everything isn't properly heat shielded you could hurt something else like wires, starter, even ac lines if they're touching.

[@myorganicaccess3869]

Amperage draw equals power loss IE: 6 interior bulbs sear belt warning light door ajar indicator on door/ key chime comes to about 30 amps check alt belt and see the increased tension. Your c5 horn draws 20-30 amps alone with a 20-30 second recovery time at 1200 rpms so next time engage seat belt behind the seat and shut the door as every little bit helps , ps it's bade enough the front parking lights are on with a 8-10 amp draw ....

Your comment seems to be meant for something different than this DYNO video??

[@myorganicaccess3869]

Eeking out HP, most over look, in most cases the minute power loss due to amperage draw , but in some cases can equal 1 HP depends on what's drawing and how much your alternator is working to produce the electricity to compensate.. In the old days we installed alternator defeat switches for the 1130 feet.. buy the way best c5 information videos on the net I have learned so much from these and are very entertaining at the same time.

That is one generous dyno ill tell you what! Making 585 to the tire from a 380 motor hp car is nuts from a sc. thats over 250 to the tire gain all on stock parts except springs

[@Toys4Life]

Keep in mind I'm also running e33 and 80 lb injectors. Boost is pretty close to adding another atmosphere. Also, motor trend did a piece several years back where they went to five different dyno places in the same day and got five different numbers. They're definitely is some variation between Dino brands, Dino models, and other factors. It made more with STD smoothing, so I changed mine to the more common SAE which is lower. Always check that as well.

Ken you continue to out due yourself, Love the Dyno tuning, Before you started any pulls I thought maybe 600 whp. You do a great job w the HP tuner system, engine is plenty safe. One thing I did not see was a boost curve?

[@Toys4Life]

Thanks Dave! Good eye on the boost curve. I have a 1bar Map sensor so as you see the map just stops at 1 atmosphere. I should look into swapping in a 2 bar map sensor so I can log that as well. I do record the boost gage once in a while to make sure everything is in order (12-13psi usually) but a 2bar map sensor would be best!

[@Toys4Life]

I agree but I know I'll get greedy and start breaking diff output shafts (as I try to get that 60 ft time down from 2 seconds to 1.7) so I just have to draw the line somewhere and so far I've been fortunate.

[@PNW_Car_Mods]

I will sound like a broken record. Those are fantastic numbers for a basically stock LS1. Nice to see shops still doing rentals. I hope to do something similar with my car in the near future, but I refuse to pay 600 dollars for a car that is already street tuned. Just need a little flexibility.

[@Toys4Life]

Yeah if you lived here, you can get in there get strapped up and get your business done in an hour for about $190 bucks on a weekday evening. Curious, where do the $600 figure come from and what would that include in your area?

[@PNW_Car_Mods]

@@Toys4Life In my area I would say an average dyno tune will start around 400. Cam swap tunes will be 550 to 600. Boost only is around 500. Boost plus heavily modded engine can be well over 600. The problem and I've experienced it first hand on multiple cars is that they rarely fully tune the car in a given 2 or 3 hour session. So you just paid a metric ton of money for a half assed job that may or may not run and drive well. I've got a few leads on some shops around here that are less than 200 miles away that will hopefully be willing to work with me some where in between a rental and a full dyno tune. In a perfect world my car would still benefit greatly from getting some slow speed parking lot manners dialed in on a loaded dyno.

[@pietrobaggi24]

580-ish rwhp! Man, that's awesome, it means about 670-680 at the crank, like a C8 Z06. Congratulations! Love your vids👍👍👍.

[@Deathbytireiron]

Nice HP. Sorry if I missed it, but how many lbs of boost? Do you think the price of a new supercharger kit is worth it? I'd like to get a used kit someday, but I worry that it wont be 100% complete or parts will be worn out or something.

[@Toys4Life]

I bought mine four years ago I think and I have zero regrets, it's been reliable and the power difference is Major. If you're not going to keep the car very long, then no. If I was going to buy used, I would call A&A Corvette and see if they have a used kit. Those guys have earned my trust.

[@halestorm867]

I may have missed it, is your tune scaled? Mine runs off the bottom row of the timing table. It hits 1.4 g/s air mass somewhere around 4500 wide open. I've got mine capped at 12 degrees, so I lose out on some midrange. But with 592hp and 520tq I can't be too mad, it pulls strong.

[@Toys4Life]

My tune is not scaled. I just checked the scan and I also hit the 1.4 g/s row in the 585rwhp pull I did. Timing advance at 5600 RPMS was 18 degrees. You have more mods than me if you are making 592hp with only 12 degrees of timing. Pulls like a beast on the street - as you know from your numbers for sure!

Very nice numbers with only a blower. Makes me think about getting a C5 instead of a C6. Lol. Do you think the engine and transmission will hold up? I was reading on some corvette forums that many like to stay around 575 RWHP to be safe on a stock engine.

[@Toys4Life]

Thank you! If you get a C5 go with a 01 or newer. Stronger rod bolts and the manual has a stronger torque tube. No on knows for sure where that durability line is with a stock bottom end engine. After reviewing all the threads I could find, I settled on right where I am at - which is around the 575RWHP you mentioned. I

What kind of fuel were you running at the time of this video ? And are you gonna go full E85?

E33. I'm getting full ignition timing without any knock on e33 so it is good enough. Regular 91 octane was not good enough to get full ignition timing.

[@kevinguillory9491]

Did you change you map sensor for 2 bar or 3 bar tuning?

[@Toys4Life]

I did not. Why? Before buying the kit I read extensively every thread I could find about going with a 2 bar MAP and modifying the tune vs ravaging the PE in the stock tune. A&A has had good luck with the 2nd method. I decided to try method 2 and if it wasn't meeting my needs - or- if I found my AFR was not staying where I wanted it at WOT - THEN I would go to a 2 bar tune. I keep a very close eye on AFR's and over the past 5 years it has always been very close to the AFR I desired at WOT. So, I see no reason to do so with my setup - although I may do it anyways so that I can log boost.

Are you completely stock exhaust?

Yes - except I have a Z06 mid-pipe setup that uses different main cats and got rid of the pup cats. That is worth at least 10hp (probably more) over the stock 2003 C5 midpipe.

@@Toys4Life you should try and find the stock Z06 cat back, little more noise but still stock appearing, obviously headers would render large gains
