Total Engine airflow does it again.....
One of their customers just swapped out their current Stage 2 heads and went to the Stage 1.5 Total Engine Airflow heads and picked up over 20rwhp. If you want to know who's heads he just took off well your going to have to follow the link. If you are in the market for heads you cant go wrong with Total Engine Airflow's.

Re: Total Engine airflow does it again..... (Phil97SVT)
He picked up 20 HP because the 5.3's raise compression and he admits his cam was too small to take advantage of the the previous stage-2heads,if the cam is not properly matched to the heads you won't get the maximum gain.I see guys all the time,mixing one tuners heads and another tuners cam,and the combo doesn't produce the right numbers,this is a classic example.

Re: Total Engine airflow does it again..... (STEALTH C-5)
Check the specs on the TEA S1.5 heads before you scoff at them.... they are quite a good setup, and I think that they probably put a lot of other 'Stage 2' heads to shame. TEA puts out a great product at a great price, and believe it or not, they are doing quite a good service to the DIY LSx community.
It's funny to see just how much the 'current generation' LSx heads (including the 4.8/5.3 heads) can flow and put the 'pioneer' heads to shame. I switched to the TEA 5.3 heads and have been loving life ever since. :flag

Re: Total Engine airflow does it again..... (Phil97SVT)
Just FYI...stage 1.5 is a stock ported cylinder head with stock valves. I do agree raising compression will increase HP but the rule of thumb is that for every point you raise compression the HP gain is 3% so if you raise 10.8 to 11.1 you will probably see less than a 1% HP gain. If I am off base please correct me.

Re: Total Engine airflow does it again..... (Phil97SVT)
Actually, TEA stage 1.5 heads use ferrea 2.02 valves, stage 1 uses stock valves. TEA ports all their heads exactly the same, the valves and spring/retainer combo is the difference. The stage 1.5s use stock exhaust valves while the 2.0s use aftermarket 1.57s.
TEA also opens up the chambers a bit on the 4.8/5.3 heads to unshroud the valves and changes the shape of the chamber so its ~64cc unmilled.

Re: Total Engine airflow does it again..... (kp)
I think it highlights the need for a "package". You can't buy the biggest "this" and put it on the biggest "that" and expect magic. A careful selection of parts that work together will yield more power. Commomn sense say that if you know Vendor X's heads work best with this particular style of camshaft and you ignore that and go with one it is not designed for, then don't expect good numbers. And, if you install a set of heads optimized for that cam, while they may flow less on the bench, they may make more power...
With all that said, TEA produces good inexpensive cylinder heads...

Re: Total Engine airflow does it again..... (AllCammedUp)
I'm not 'scoffing" at them,they seem to be a good reasonably priced head,and in the above link they worked better with the smaller cam that was used,but when someone comes on here and says they gained X-amount over another tuners heads,when the other tuners heads were mis-matched with the smaller cam,I wanted to set the record straight.

Re: Total Engine airflow does it again..... (my00c5)
wow...........5.3 heads can be used??? Thats quite interesting :yesnod:
5.7 Heads, include LS1 and LS6
6.0 Iron LQ4 Truck Head used for pre 2001 6.0 liter truck motor. Designed like the LS1 Head. Just a bigger chamber for the bigget 6.0 bore.
6.0 Aluminum LQ9 Truck Head used for 2001+ 6.0 liter motors (also in escalade 4x4 and caddy EXT). These heads are desinged like LS6 heads, just bigger chambers for the 6.0 liter bore.
And lastly of course the aftermarket C5-R Racing Head, which requires extensive porting work from new, and a custom intake.
All these heads are interchangable with 4.8/5.3/5.7/6.0 GEN III engines. Not necessarily optimally.

Re: Total Engine airflow does it again..... (Phil97SVT)
Brent I would relax alittle bit,TEA does EXCELLENT work.
Just becuase they dont run 10's with a H/C Vette doesnt make them ignorant to porting.
I dont think u wanna play with any of there Ford stuff.8.80 to 7.60's is alittle outta your league bud.These guys build and port for big name NSCA/MNRA racers,There very good and know how to port very well.....
Stealth made ALOT of sense without looking like a BOOB.
Its all in the PACKAGE and thats the only way to make power correctly.
Now what I will say is the Cartek SII's u were comparing were a 1.5yr old,TEA on the other hand is starting with NEW R&Ding of their port design so they are right there now with most of the other guys in terms of flow#,stall,port volume,etc.
I'm sure if u had Carteks LASTEST port design along with the proper cam grind from Cartek u would see a more accurate comparision that would be more consice....
Throwing numbers around is a BOOB LIKE thing to do.
There's really no validity to this post at all.

Re: Total Engine airflow does it again..... (Pewter Ram Air)
Like JS said TEA is building some major power in the NMRA 5.0 racers. They are just breaking into the Chevy world. Many members of other boards are getting great results out of these heads. 20 rwhp maybe due to the old port design of the Cartek heads and need to have a cam matched to what the shop intended. Reguardless these are good numbers on a heads and cam from an independant dyno. Just because you don't hear of a company doesn't make them a bad head. Maybe if they were a "sponsored" :rolleyes: vendor we would hear more about these heads. :yesnod:
