Can I get another 50hp for under $2000?
2017 ZL1 A10 with ported tb, LT's with high flow cats, 9.17 lower pulley, e85 sensor, roto fab and tune. Currently about 645/685.
Wondering how to add another 50+hp for less then $2k without doing any fueling mods other then possibly a low side boost a pump and having this thing continue to run cool enough for road racing? |
With the lower pulley increasing boost you may already see increased temps on road course. You might need to look at cooling upgrades. JMHO

With a pulley and the big power increase you already have, your car has already lost a lot of cooling capability on a circuit. On a warm day, maybe any day, it will overheat. Have you tested it yet?
If you add anything else, it will get hotter. You could look into this: https://jannettyracing.com/collectio...019-camaro-zl1 It uses no pulley, stays cool on track and boosts power to 800+ BHP. You don’t need more than that on track except DSSVs, wide R comps and ZLE aero to beat anything but a 720s or similar, if you become a great driver. |

ported blower and 103tb?

x3 for the ported SC and 103TB. This will free up air flow and reduce restriction. It will decrease your PSI and reduce IATs a bit. Might reach your goal there but you will be completely maxed out of fuel at that point.
All of this sets you up nicely for a cam in the future. |

I wish I could explain how with close to the same mods as you (rotofab/LTs (catless)/9.17 lower) I am making 717wtq. Seems so weird.

The torque gain just seems so much higher than others that I have seen. It honestly has me considering trying another tuner just to make sure its all good and not leaning out too much on initial acceleration. https://i.imgur.com/VTYmm9t.jpg |
Could be how the timing map is set up by the tuner. Some pull a lot of timing in the low-midrange part of the timing map to soften the torque. Others run a lot of timing in that area which will make a lot more torque on the hit.

I went back and checked the dyno sheet from Cordes after they installed a cc.
642hp/698tq SAE on a 108 degree day using e40. I've been to one 1/2 mile track day with this car and 1 day road course though I've been roadcoursing for 20 years. On the wildhorse east track in Phx a few weeks ago that started out at 68 degrees the first session but by the 3rd session was 93 degrees. Watching the cars temp readout for trans (max 223 degrees) and the aeroforce gauge for coolant and oil temp (max 238/246 degrees) I was pleasently surprised to see no overheating. Perhaps running e42 helped? The east track is relatively small with a short straightaway (120mph max) and technical with lots of turns. I've leaned toward porting the blower and then going the bigger tb and big gulp, but Cordes thinks I'll be running out of fuel with that arrangement, even with a low side boost a pump. Seems I'd be pushing that 700wrhp mark then and I thought the low side boost a pump would take care of that, but I admit Cordes has a whole lot more expereince with these then I do. He suggested a cam for power and fueling, I'm just not sure I want to go into the engine and then I'd reason, hey while you're there...port the heads as well. Next thing I know I'd be into it $6k vs below $2k. Yikes! |
