I just got off the phone with Gary Herche! He dyno tested the prototype TA Buick 350 intake on a Buick 350 a few days ago and he was really happy with the numbers! With a 1979 Buick 350 with 9:1 compression it made 470 HP at 6400 RPM, and they are getting the 79 Regal to the track to get the 1/4 ASAP to get the real world track proof to back up the numbers. Gary Is not much for the internet but the findings will be posted by Troy Acton ASAP.
Engine dyno, and I am not sure about the headers or not.... But in the NHRA class they are allowed headers so I am sure they have custom headers or headers modified to fit. More info will come out, most likely from Troy Acton.
The big news is when can the intake be available. I think I may call for a deposit this week. I need a few other things anyway
Well if its truly a Stock Eliminator type build, then the only info that would be worthwhile to most folks on this site, is if they dynoed the engine with a dual plane,and then switched over to the new intake,and what THAT MANIFOLD ONLY power difference waso No:
I would imagine they would have tested it against the best previously available manifold.. would be disappointing if they did not. Hopefully Troy will be along with more details on the build. JW
Agreed. Great numbers and all, but to really quantify it I hope there was a dual plane dyno'd then swapped to the single all other things remaining the same. I really look forward to seeing those type results. Still, great news that testing has begun.
Yes they completed testing with other intakes... We will hear the full report about the testing from either Troy or TA... They even had some testing done with a mopar intake modified to fit a buick 350. I wont quote numbers for the cam etc but they are limited by the nhra rules so stock lift but lots of duration cam, stock valves, no head porting, factory dish on low comp piston. With a stock intake and numbers matching q jet these engines make about 390 hp, as Gary has given me info towards my book... Gary was super excited about the intake and said "ta hit a home run with this intake!" The intake was gasket matched by ta before they shipped it to him, however the heads were not gasket matched so there was a restriction with the intake port being larger than the head port... Even so it still made great power and TA is shipping him a non gasket matched intake to use at the track for more testing...
This is great--showing that a single plane intake can still benefit an engine running low lifts, as the untouched/cleaned up heads will only flow up to .400 lift. Imagine what will happen with freer flowing heads and a roller cam! It wouldn't surprise me if this intake performed well on a bone stock engine (with a '68-'71 style OEM cam, not one of those peanut grinds that came later) with cleaned up heads and large tube primary headers... Those 'stock lift' cams with 'high duration' that comply with NHRA rules are most likely sporting embellished asymmetric ramp rates similar to the OEM cams, I'll wager. That's what I'd do if I were engineering such a cam... :Brow: Gary
only oem intakes are used for nhra stock classes, intake would not be nhra approved for stock classes. super stock and everything else is a go. wonder if gary liked the response time in using the s/p.
I am pretty sure this is just an intake test, and they would not actually use the intake for the Stock Eliminator class racing.
