Are your leads unusually close to the manifolds ? You're still on stock manifolds ?

Stevie,

Stock manifolds, ceramic boots with DEI heatshields. Nothing got burnts, but damn those ceramic boots were too hot... I could feel the heat thru my mig welding glove.

I've been using some cheap ass leads for a few years now with no issues and truck manifolds.

I did use the Firecore with their "promod" boots before again with no issue. I only changed leads as I needed longer as I changed to IGN1A coils and needed a couple of inches longer leads. So I DIY'd some from some Ford Explorer leads which had almsot identical plug ends to the Firecore.

The Firecores do have a slight angle to them, so would be a little better fit, but the leads I used are still fine.
No heat shields or anything silly which more often will trap heat in after shutdown and cook everything.

I do retain the factory heat shields on the manifolds themselves and did do a very light wrap around the manifolds under the heat shields with DEI wrap.

Some images of the Firecore here, although the bend in these is more pronounced than mine were.
But that would allow the wires to turn up away from the actual manifold tubes quite well

And the type of leads I bought and cut to length. Just some cheap crap really but boots are identical design. Wires themselves were just the usual fibreglass type strands. If they ever turn into a problem I'll consider replacing them, but so far they havent. Just cut these and crimp on some new ends.
Only reason I didnt buy firecore again was I didnt know what length I needed and I needed to get up and running quickly and they never answered my emails, so just said **** it and ordered these to cut up. At least now I'll know what length I need if I do upgrade.

Stevie, thanks for the info. I should ditch the DEI plug sleeves so it doesnt retain heat around the wire.

Where possible, I always prefer an airgap and allow air to move to keep things cool.

IMO all those sleeves and wrap for leads may protect to a certain degree...but once you've parked up after a blast, they simply turn into cookers and fry everything inside.

Haven't updated in a while...

Pulled the Billet Twin and went with the Monster Triple. Got it back on the dyno yesterday and with 6psi springs in the gate, I was only able to pull the boost to 15psi with EBC.

Car ran well... made 926rwhp/883rwtq @ 15psi.

Injector DC was 70% @ 6k rpm (peak power was 5700rpm).

I believe the intake/filters is choking the setup up top... but its fine for now.

These are STD numbers... I'll update once I have the SAE numbers.

Next steps is increasing the WG springs so I can pull the boost to 20psi with the EBC.

I was picking up 34hp/psi... so should be able to easily hit 1000rwhp @20psi if the injectors are up to it.

Off to the dyno again today with more gate springs…. Starting at 12:30pm EST. Stay tuned for updates.

How'd it go? 1100ish?

Thanks for following!

Unfortunately the fuel limits were reached. It was pretty warm out too...

Timing was being pulled due to the temps in the shop... at 15psi I was getting 13.5 degrees timing vs 15 degrees last time. We didnt want to start modifying the timing tables for coolant temp.

Raw numbers weren't bad...

18psi - 945rwhp/983rwtq timing at pk tq 12 deg, 13.5 deg pk hp, 11.5-11.8 A/F

20psi - 990rwhp/1031rwtq.... but stopped the run at 5400rpm because it was lean timing at pk tq 12 deg, 13.5 deg pk hp, 11.7-12.0 A/F. Injector DC over 80% and fuel pressure was dropping off to 45psi during the run. It wasnt happy as hp peaked at 5100rpm as seen in the graph.

I called it quits at that point as I'll need to address the fuel system... Not bad for 1000cc injectors, FPCM and ZL1 pump. Meth really let me stretch this fuel system.

FYI... we were very conservative on the tune thru all boost levels as well were trying to get to the high boost. So we were high 10.8-11.2 thru the lower boost runs.

Here were the SAE numbers with the conservative tune:

8psi - 660rwhp/744rwtq (wastegate) 12deg/15 deg and 10.8-11.2 A/F
15psi - 872rwhp/894rwtq 12deg/13.5 deg 11.0-11.4 A/F
18psi - 923rwhp/960rwtq 12deg/13.5 deg 11.5-11.8 A/F
20psi - 966rwhp/1006rwtq (partial run) 12deg/13.5 deg 11.7-12.0 A/F

Conservative timing... need more fuel... made about 15 pulls... will go back after I address the fueling. She will absolutely do 1050rwhp for sure.

nasty torque! I can't believe you made that much on just a ZL1 pump and tune. You must have been spraying a ton of meth.
