JANNETTY RACING ZL-1 NO TUNE PULLEY ROTOFAB TESTING RESULTS

If your going this far, your voiding your warranty anyway so a tune would be the best way.

IMO, sounds like the IAT2 temps might be a culprit. What were they during the runs?

Could this test be repeated with 91-93 octane and appropriate tunes for each combo?

- I am assuming knock retard is when the motor automatically pulls timing due to detonation? If the motor automatically compensates for the knock, then do we have to worry about anything?

- So what you are saying is we can install the 10% OD pulley and the CAI, run 97 octane (via TORCO additive) and get about an 80rwhp increase over base WITHOUT a tune and WITHOUT hurting the motor?

Correct 75 RWHP

IAT 2 Temps were very good and recovery is very good, best I have seen vs all the aftermarket superchargers.

Thanks,

Ron

Looking at the other tread, 510hp with the 10%.

Looks like it would be best to do one part or the other at this point.

Ted,

Thank you very much for taking the time to test, it is very appreciated.

Your Welcome,

No codes are set but knock retard is too severe with both the 10% and the CAI so either 100 octane unleaded or Torco Race Gas Concentrate should be run with this combo to see the results I did SAFELY.

You are correct on 93 one or the other is fine.

The 5% and Rotofab worked well on 93, 92 octane may not be sufficient so a little Torco added for the days when your using the power would be advised.

Thank You I Really appreciate that, it cost me a lot of money to run these tests so if everyone buys they're Rotofab from JRE it Really Helps offset the cost of doing the testing.

Not without a tune since it will make the car rich.

Again you would need a tune and this whole thread is about NO TUNE POWER UPGRADES.

Again we are searching for no tune power options.

I have no Problem tuning these cars, I just though it would be neat to find out how much GM left on the table for us.

It seems to me that tuning should be considered if you're going to add more than a CB or CAI. I am thinking this because it's not like IF the car were to have a problem, and it's taken to the dealer, that they're not going to notice marks on the upper pulley shaft, or that it is a smaller-than-stock diameter; nor are they likely not not notice either wrench marks on the crank balancer pulley fasteners or a larger pulley. They're going to see these clues and if the claim is drivetrain related, they will probably come to the conclusion there were modifications. I think the conclusion I'm drawing is that you might be able to get a good 30-50-horse' out of the car without tuning or major bolt-ons that a dealer will have a problem with, but that might be about it - safely...

Thanks, Ted, for the outstanding testing and attention to detail. Mucho KUDOS We haven't heard of many problems with mod'd cars, so it seems to me it's up to us to find qualified and experienced tuners, like Jannetti, and take our cars there

Appreciate the response and your time an money into this r n d. I will b ordering the 5% pulley and roto fab intake ere in the next week or so

[NickJRE]

They are now up on the site in case anyone was wondering.

ZL1 Roto-Fab Carbon

Nick

Thanks for the great service this morning on my order! JRE's service and testing information is why I continue to buy from you.
email me a tracking number when you get one.

Thanks again!

I agree but that puts This topic Off topic.

The goal is What can we do without Tuning, 75 RWHP is Pretty Damn Impressive.

Thank you sir.

Ted.

[Deke736]

So, if I typically run 93 octane my best option is to go with a 5% pulley and a CAI? Would I only need the Torco on track days?

The Rotofab looks nice and obviously has great performance, but I am still waiting to see what CAI, Inc comes out with!
