Holley Sniper intake has shipped!!!

[z06psi]

Results are in!!!!

So 667rwhp was the last pull.

Only two changes since. Cat deletes and this manifold and it picked up 54rwhp and 20 rwtq!

Cat delete was probably good for 30 and the manifold for the other 24. DA today was 1186' and the pull was in 5th gear.

As you can see from the first 667 pull I lost a little bit below 4K but gained it all above that. This pull was all the way to 7750 r.p.m

Oh and another thing. The Procharger inlet has no real restriction. I took off the entire inlet tube and it did not impact the readings at all.

That happened at the end of the pull there? Doesn't look quite like normal rev limiter to me. If it is maybe raise it some and see how well it does past 7000 now with the new mani.

Dyno operator said it isn't picking up the rpm's right from their sensor. Still rolls the rollers regardless.

If I had to guess. It looks like their pick up is about 1000 r.p.m. shy.

That makes sense.

Nice numbers, looks to be a solid mod, hopefully there will be some NA testing on this as well.

I bet there is definitely more to pick up over the entire band with more vct work.


This wasnt a dyno remote tune with lund i take it. He just sent you an email tune and once it drove fairly decent you took it in. Would that be correct?

Yes. Living in Hawaii has it's drawbacks.

Of course. I asked because i believe there is still a decent chunk of power left on the table. Thanks for being the first non vendor to take the plunge to show people this intake is arguably our best non custom made choice for FI.

There probably is. However, only having 92 as a source for fuel here and the fact that my goal was only 650rwhp I am pretty happy.

If I keep this car then the next step will be large one. I am now done with this mods on this car for now. I have to re-build the Corvette.

Looks like your dyno operator made that on an etch a sketch. What kind of dyno sheet is that?
Your hp/tq should cross at 5252.

 

[Kellys69z]

So did your runners look like this? Every port has over penetration, and needs cleaning up. Tomorrow I am taking the boss off for a gt350, than in a few weeks the POS holly is going on for a comparison.

Well aware. Talked to him about it before hand.

Again. I am happy with what I have. It is a daily driver. Not an all out racecar. The Corvette is that.

 

[Deranged1]

Appreciate the results. Looks to be a good intake and I agree with mustang guy, should be more results with VCT tuning. Can't wait to see comparisons between the Holley and the gt350 manifolds.
