419wHP EvoVIII on pump gas dyno graph
Hi all, here is a photo of the Pesto360's best and last dyno pull of the night. As you can see it took 9 pulls to achieve 419wHP on pump gas. Of course we did part throttle and some basic street tuning before we hit the dyno. This was done without any additives to the fuel system or intake system. No octane booster, no unleaded or leaded race gas, no aquamist or nitrous.

can we see some dyno charts as a function of RPMs, to see how much power is being lost down low?

Well the car is back down at SFP now to squeeze some more out of it...lets see what we can get...I think they can squeeze out quite a few more with the aquamist...
Good luck scott and frank

That is very impressive on 93 octane. Where's AL now?
hehehehehe - ohoh - hope I didn't start anything. :

The dyno curve is virtually the same as mine - only difference is that mine is a bit stronger down low - however - they only had 9 pulls they say so I bet with more dyno runs (I have over 300) - they will figure out how to build the spool up faster and harder with some timing adjustments
I am going to tune with some street gas 93 octane tonight and do a dyno pull tomorrow to compare - should be right about the same curve - maybe mine will be a bit lower as I always run a rich a/f - we will see
BTW - its a dyno jet they use - same as mine
The a/f curve if it was readingv properly - says 11.7 - a bit lean for the street gas for my taste

You have said that your turbo kit (which looks to be very reasonably priced) uses a different turbo which is a little bit slower to spool, but which will make more hp for more rpm's, and is MUCH less expensive. 
Can you offer a setup that will make similar hp to above on 93 and have a similar, if not better spool-up then the stock turbo? You guys seem to know what you are doing, so I would like to see what you are going to come out with. I am not really as interested in a screaming top end hp monster that needs either nitrous or 100 octane as much as I would like the hp above, which was on pump gas, and some good mid range spool-up and torque. I have heard several conflicting reports as to how much hp can be made on pump most of which say that about where you are now is the limit, what have you guys experienced to be the limit? I just want to run pump and normal rpm's, say no more than 7800-8000. I just do not know if there is an advantage in giving up spool for a huge turbo when you could not utilize the performance without high octane or nitrous. Thanks for your time.

John - congrats bro - even more impressive than I thought.

Yea, it may be a pretty tall order to fill, but these guys seem to have a pretty good grasp on how to get things done, so who knows? I just do not think for what I would like, which is for a reasonably early spool with good mid torque and pump gas, that a gargantuan turbo that starts to make it power right where I would like to cut off would be very smart. Hell, I might even be better off with the stock turbo, thats what I am trying to find out. But with a good manifold setup I was thinking that it might be possible to go up to a larger turbo that maxes out around 450 hp on pump, and get a good mid spool like the stock in the process. I don't want a huge turbo to go above 450 if I can't do it on pump, but I would pay for more power from a turbo setup that is well engineered with a smaller turbo, although bigger than what I have now and would still be responsive.
Maybe hit the torque a little earlier and peak the hp earlier, say a max of 430-450 wheel, to where it starts to fall around 8000.

nice charts BUT IMOP peak HP isn't everything for a street car. I'll be happy with 400whp or even 390whp if I can get it to spool at around 4-45k.
I've got another 80whp to go
