Went to the dyno to mostly check the belt and made a few pulls.Tuning was just basic with 14 degree's in the torque range and 16 degree's up top.The dyno sheet is comparing the N/A to the lame 10l-11lbs of boost.The fuel injector's are already maxing out with 60lbs of fuel pressure. The Turbo isn't in the efficiency range yet as the difference of 8lbs to 10lbs was almost 100hp/100tq. The puill was done with a cold turbo so spool was slower than the other runs I did.Normally the turbo started to spool at 3000rpm and torque peaked at 4200rpm.
Someday I'll spend some more time on the roller's and really see what it can do

 

insane for prelim #'s don once the kinks are out and you can use the good range of the turbo it will be ridiclous . very impressive

 

does that say 667hp 687tq ,10psi on that turbo isnt even efficient..isnt it like 16psi?

 

You still have plenty of turbo left and still be on the map's island.




Here is the consumption chart for a 408. It is a conservative map though I built using a lower VE and 120 degree intake temps. IF you need an accurate map let me know....I should be able to show what you will map before you even roll it onto the dyno again...hehe.

408 consumption

I cant tell if it says 567 or 667..... bigger graph....

 

Very nice for a shakedown pull....you've built an impressive system........I'd check the a600 before the injectors if it's boost referenced

 

just look to the side of the graph for refference

 

I want a T88

 

awsome numbers for the little bit of pressure.
what injectors are you using now, curious cause im going to start at about 12psi with my little 347 and 42lb injectors, and might need to reconsider

 

if you turn the boost up will that have any affect on the spool time? like when you go to the higher levels more exaust will be allowed to reach the turbo before the wg steps in to release it. cant an eboost hold the gate shut and allow it to spool quicker. i dont know im just throwing some questions out that ive always had

 

It will just take the additional time for it to reach higher boost, little time. The eboost can hold the gate till whatever pressure you set it too.

 

Don't even waste your time, you're going to max those injectors out.

 

The HP is 667hp. I spent very little time tuning on the street.The dyno was to just make sure the belt would stay on.While there we messed with A/F and noticed the fuel pressure stayed at 60psi all the time indicating the pump was good so far.
I was tuning to uncorrected #'s which were around 700hp720tq or so.We are just happy the car runs again By just seeing a 100hp increase going 8psi to 10psi I'm sure this car will rip when we get 14psi on the street and possibly 18-20psi on race gas

 

Congrats man that is sweet.

 

Yes the e-boost can help by allowing boost to be blown to the top port of the gate to help keep it shut from quicker spooling.

 

Great work Don and Mike 660's and its not even spinning hard yet

Forgot to mention that I didn't even open the cutout These were run through the single 3" exhaust.The cutout is in the 3.5" pipe

Also need to work on the oil system to the turbo.On decel there was smoke which seems like I might have to restrict the oil feed line since oil pressure goes to 70psi or so near redline.

 

yeah, it's OK i guess. lol, j/k. that thing's gonna be insane. I'm sure there's no way I could afford to have you build one for my 408 but a boy can dream, oh yes, a boy can dream.

 

what heads are you using, and what are the specs on your cam. I know how 9 psi feels on a 408, once you get past the traction problems that is.

 

PurEvl must be a happy man right now! Congrats on the first run numbers, can't wait to see what this thing puts down once everything is finished.
