9 liter extreme at Prefix Nearly there

[stradman]

Well excitement building up! Car is pretty much nearly complete! Had car on rollers yesterday at Prefix(video coming soon!) and produced what it was expected to produce at this stage(I'm told this is a "green" engine still), so all good! A few final tweaks I gather and car will be ready to get shipped back. Been a long time away from me-had to ship across the pond- and so can't wait to get it back! Scot and Dick have been excellent throughout, and duly confirmed all the previous glowing comments from others!
Summary of all mods to my car thus far( and a couple to come):

9.0 Liter Extreme Stroker kit
Upgraded oil lines
Higher pressure radiator cap
Accusump oil accumulator
Modification of DSE shield to accommodate Accusump up front.
Mocal Differential and Transmission Coolers,
Wavetrac Helical LSD
Triple Carbon clutch
Change of first 4 gear ratios to Gen IV cluster(Dick's advice), and 5th 0.8 and 6th gear 0.63
Shot peening of gears
Ross Murray Roll bar
Prefix sports 100 cell Cat
Plasma coated exhaust from tip to headers.
Increased heat insulation sills
DSE catch cans
Underdrive pulley
Lithium ion battery
Titanium lugs
DSE extended diffusers and splitter
Girodisc brakes ST pads
Forgeline 18/19 wheels
A/C cutout @ WOT delete
TBC lightweight carbon seats Tillett

And just waiting on my new CF airbox with 9.0 L instead of 8.4L on it!

Can't wait to see some on-track action!

What's the story on the exhaust tips? Help reduce noise to comply with track noise level restrictions?

Yes. Well that's the theory at least. As it stood, the exhausts blared straight onto the noise meters as I blasted past. Maybe now as the tips are directed slightly downwards hopefully might help with noise restrictions. We'll see I guess..!

Good luck! If all else fails:

beautiful. I love when people post pics like this I can look at them all day. that coating on the headers gonna be enough to keep the heat down or could you benefit more by wrapping them or something.

Here is what I found out with a decibel meter on custom Harley 110 inch motor... with the pipes turned out to the side it was louder to those who were next to you.... but when i turned the pipes where the opening was turned down it was quieter to those along side of you BUT standing on the infield of a race track it is louder tuning exhaust toward the ground..(sound reflects of of road surface and is louder).So the difference is where the listening party is in comparison to the vehicle.
With a h/c v-10 with cut outs with turn down openings... at an idle.... it will be an event.... for us seasoned ole farm guys.... it will bring back memories of that “B” John Deere on a cold morning plowing 2 year old alfalfa field...ahh the good old days..... lol

Yes. Well tbh I don't know what exactly will happen. Which is why we turned them slightly obliquely and not 6 o'clock to lessen bounce off road. We'll see I guess...Worse case scenario, if its worse I can always just saw off the extra bit and make it flush again.

Holy moly!! It's going to be a completely different car! That's awesome.

Congrats dude!!!! Can't wait to hear your write-up after your first track event!
"A/C cutout @ WOT delete" So does that mean you can run your A/C while on the track?

Cheers buddy!
Yes. I discussed this with Dick. On WOT(and there is a lot that going on on track! hehe!), as you may know, AC on OEM cars cuts out to preserve horsepower to engine(he reckons about 4-6 hp on a good day). Well with an over 800 hp engine Cable, I can afford to "lose" say 5 hp to stay cooler. After all I am not into any competitive timings, so losing a tenth of a second on my lap on track is ok with me.....

Wow what a build. Congrats!

im cuious on the accusump decision.. was that a prefx recommendation? same with the differential.. i thought the stocker was quite stout.

also whos oil cooler lines did you use? DSE?

Prefix sells the accusump kit.

i thought the swing arm oil pickup took care of a need for this.. i know the vette guys swear by the accusump.. but alas they dont have the swing pickup

No it was my decision. Even though the Viper has a Swing arm, which is good, its still no dry sump. Ultimately dry sump would have been the best however that is both a more involved and costly conversion. Accusump is probably a good mid way solution-a sort of small peace of mind. If you don't track the car ever of course you would not need any of this as the standard setup is good. And even for those that track its probably ok, but as I said just an extra security layer. Not sure which oil lines Prefix use. Maybe Scot could chime in.

2nd and 3rd gear also change, the whole cluster has to change, you will love the new gears.

Didn't know that Jack, and wasn't explained that so that's news to me. I thought it was only those gears. I've kept same final drive.

Your new 2nd gear will make you think you are in 1st gear. I know why SRT selected the G5 ratio's, but, the G4 ratio's feel so much stronger in the G5

We have our own AN oil cooler lines. You can get them cut to fit, or assembled to length.
Black fittings with choice of all black hose, black with blue stripe or black with red stripe.


With the race like idle and just off idle characteristics the 2.66 first gear helps with taking off. Makes low speed driving much better

Sweet build Strada, this thing is gonna be a beast on the track! I can't wait to see videos of this car.
