1100rwhp tuning results/fuel system limits

[biminiLX]

Well, I’m happy overall.
Hard to be upset with an 1100rwhp SAE 7500rpm street car.
Due to @Justin@VMP being in town and the Woodward Cruise weekend, I moved up my tuning day a week early with my friend Lidio at Alternative Auto Performance.
On Friday we found that as soon as we started pushing the tune and commanding more fuel, we had pressure drop.
It appears the Fore triple pump fuel system and ID1300s were maxed as the Walbro 465 pumps (high pressure 450lph) were done after 2.5 years sitting in E85. Unfortunately it seems these pumps and many others are very hard to find now. Did some driving around Detroit to track down new pumps but could only find one 400lph and two regular pressure 450lph.
On Saturday after swapping in the new pumps and watching friend Eric Turbushs Gen 3R S550 hit 1100rwhp, we put my car on the rollers.
Long story short, but last year with an unported Gen3 VMP blower and VMP 173 TB, it made 1022rwhp SAE with 23-24# and 22-23deg timing.
This year, on the same 15% lower 2.4 upper pulley set up, with the only changes being a max ported Gen3R secret sauce blower, VMP 163R TB and exhaust cut outs, it made 1110rwhp SAE!
It was much hotter and muggy this session, but it was interesting to see the same max boost overall despite the 3R swap. This could be weather related or due to the QTP exhaust cutouts helping.
Unfortunately we still kept having fuel system issues and I have FIC1650 injectors currently in transit. You can see on the graph the TB attempting to close due 100-120% duty cycle!
Once the new injectors are here, I expect the fueling issues on C85 will be addressed. If not I’ll swap in bigger secondary pumps (Hellcat 525lph).
Interestingly, this year had a much more conservative timing curve.
The max 21deg only came in at 6500rpm+. It was only 15deg at 4000rpm slowly ramped to 21deg.
At this boost level, I’d like to see the 22-23deg max and have 19deg around 4000rpm ramping to 22deg at 6000rpm and even see if it likes 23deg like it did last year.
Really looking forward to repeat testing with the new 1650s in cooler weather and the added timing, plus early fall track rentals!

Congrats on the new #'s..

Whoa, you cracked 1100whp! That's really impressive! Looking forward to seeing another pull or two after you swap in the new injectors. And more than that, a video of your Fall track visit to see what the beast will run.

I picked up 140 whp with electric cutouts so they definitely are worth the investment. These Coyote motors love to breath!

I opted for (3) Hellcat 525's myself. I could not locate the 450's. Wow 1100 whp is no joke! My 1300's were taped out as well and had to jump to 1700's smh the price is outrageous tho! They really stick it to u with the injector pricing.

Awesome! What throttle body were you running on the garden variety gen 3?

173 on the Gen3, 163R on the Gen3R
I wanted to test the KB168 TB and DD149 CAI on this combo but I’m more than happy with the power.

Correct Bob, I’m most looking for track results.
Super bummed Mod Nats is cancelled but I may do NMRA BG instead.

Yes, it’ll be interesting to see the Dyno results when I can test cutouts opened and closed. I broke one of the connectors trying to finish wiring for this Dyno day so I just said screw it and left them wide open!
The FIC 1650s were $600 cheaper for essentially the same injector (ID1700) so I went with the lifetime warranty and FIC.
If the injectors alone don’t do the trick, I’ll replace the two 450s for Hellcat 525s and keep the smaller 405 primary as it’s more than enough for most of the street driving.
I’ll keep you guys updated but it went 9.55 with 100whp less, so I’m hoping for 9.20s in fall air.
Still, this car is ‘done’ from a power perspective for me.
I’ll focus on ways to make it perfect on the street (it’s close)!

Coyote first then 5.8:

Also, check this comparison.
Both ported secret sauce VMP GEN 3R blowers, same Dyno same day.
Built sleeved Coyote 5.0 S550 vs. built 5.8 GT500.
Both 1100rwhp SAE.
Discuss.

That coyote is no slouch. I would not have expected 118 lb ft more torque. What are the specs on that combo?

 

[biminiLX]

The Coyote is a sleeved Gen 2 motor 11:1 with ported heads and intake and Comp Stage 3 cams.
With more boost and custom cams I’d bet you could easily hit 1150+ at 82-8500rpm.
Knowing the timing curves, I was surprised the 5.8 was up so much torque. I usually run 4 more degrees at 4000rpm than this graph, so no wonder it feels so violent rolling into or stabbing the throttle around 3500-4000!

Well shit... my goal was 1100 on my new motor set up but sounds like it ain’t gonna happen with my 1050x injectors!

I’ll have some ID1300s for sale or trade. I’ll be gentle
You’ll be fine or close with ID1050x on Gas, but no chance on E at 1100rwhp,

Might have to take you up on those 1300s

Seems like as long as you have a triple pump setup and 1300s you can make over 1200whp. I seriously can't imagine how fast a 1,100whp GT500 must feel, my 800hp GT500 feels fast as hell to me lol.

Thats cause 800 hp is fast as hell lol

Lol it's decent, but I always want more.

lol dont we all bro.....

You either added that or I missed it. Big torque makes sense now. I thought the coyote was the big number.
