Re: Whats better TEA or GTP

Well from my perspective TEA heads are 1600 and verbs just put down 437rwhp with 10.8:1 compression ratio. If you change that compression to 11.5:1 you will probably see 445 and this is without tuning. Bang for the buck is definitely the name of this combo.

Its my car that was built by Raging Motorsports and being impartial I love the results.

Dads Toy<hr /></blockquote>Those are nice numbers, but nothing that TEA heads can't match or come close to. I had a set of TEA stage 2 5.7L heads milled .030 (2.02/1.57) on my 99 TA with a 222/222 .566/.566 112 cam, FLP long tubes, cutout, Whisper Lid, etc. I was using the LS1 intake and I put down 405 rwhp with stock tuning.

Sporadic's car had a set of 6.0L heads ported by TEA with a B1 and all other mods identical to mine. He put down 420 rwhp, again with the LS1 intake and stock tuning.

Don't be too quick to put the TEA heads down...especially for the money!

My baseline was 298rwhp with there heads, hammer cam, and tts headers I gained 75rwhp which is pretty good....

phillip<hr /></blockquote>Hang on now, that is an unfair assemssment. Compared to the guy who is looking at getting new heads, I have a lot more mods.

I have a bigger cam, carbon fiber driveshaft, aluminum flywheel, true dual 3" exhaust, ported TB, pullies, and all the free mods, which I don't think he has. Those differences alone could equate to some rwhp discrepancies.

HOWEVER, I assume he is on a stock rear end and I'm on a 33 spline 12 bolt w/ 3.73's.

I also am poorly tuned, and dynoed with a clogged fuel filter, bad o2 sensor and was running pig rich.

I say too many variables between our cars to assume a bump in compression will get him 445rwhp.

Who knows. I won't even begin to guess what he'd dyno.

Re: Whats better TEA or GTP

<blockquote>quote:<hr />Originally posted by 383ss:
hell, sounds like you could hit 450 then.<hr /></blockquote>Last dyno I had some tuning problems.

Once I get my car tuned and redynoed with my new o2 sensor, new fuel filter, new hardened pushrods (vs. stock), and leaner a/f (13.0:1 instead of 12.1:1)....450rwhp shouldn't be out of the question.

I'd be thrilled even with 445rwhp through a full exhaust and 33 spline 3.73 12 bolt with a mild 10.8:1 compression.

Hell, I'm extatic now, I just want to take care of all the little nagging tuning issues.

Re: Whats better TEA or GTP

<blockquote>quote:<hr />I could not convince myself that the extra five to ten HP was worth another 1,400.00. <hr /></blockquote>OK if GTP's retail for $2400 and the TEA's retail at $1600...where does the $1400 price difference come from? I have not seen TEA heads or have I ever seen a car run with them. But you cannot deny that GTPs heads have proven themselves quite well in many many cars here on LS1 tech. Not only do you see some awesome horsepower but the torque is extremely good too. I do think the whole "GTP makes more peaky numbers compared to TEA makes more midrange" statemant is crap and is from a biased source. Look around, see what others consistantly get from there cars with certain heads. Look at the dyno graph of the last GTP headed car we did. It made over 400tq at 4250 and held it there until 5200rpm!! Then look at 5100rpm...there 400+hp until you hit the rev limiter and it's up there over 400+hp easy. I can say one thing. When I order heads for my car I don't want to "hope" I am getting one of the better sets, I want to know and have confidence I am getting what I pay for. The extra cash for the extra power is definitely worth it IMO.

It really depends on your application. Bare bones heads, yes, the difference is only $800. But add double springs, 5.3L head upgrades, milling, flowing, etc...and the discrepancy gets much bigger between the two setups.

Here is the breakdown and price difference between the GTP and TEA heads for my application.

TEA heads:

$1500 for stage 2 ported heads (usually $1600-1800, but I got in on a GP)

+ $50 for a 5.3L head upgrade
+ $0 for comp 987 double spring upgrade
+ $0 for milling
+ $0 for head flowing
-----------------

Total of $1550 for a TEA stage II 5.3L head with titanium retainers milled to .010, with comp 987 double springs.

GTP heads:

$2399 for stage II ported heads
+$500 for double spring upgrade
+$350 for 5.3L head upgrade
+$??? for milling of the head
+$??? for head flowing
---------------------
$3250 at a minimum assuming they don't charge for milling or head flowing.

Right there is a $1700 difference between fully decked out stg. II heads.

Re: Whats better TEA or GTP

I bet if you mill the heads(.030) just like GTP does you will end up with VERY similar results. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Re: Whats better TEA or GTP

Like I said before, there's not many guy's out there running 10's in the 1/4 mile with just heads and cam packs but GTP and MTI that I know of and that's proven already so you can always base it on timeslips!!!! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I would like to get more info on the GTP heads. Does GTP have a website?

Re: Whats better TEA or GTP

The car Raging Motorsports just did, did have awesome mid range numbers, damn good tq and good hp. I'd like to see that graph overlaid with a graph from a set of TEA heads on a similar cammed car. A few comparisons like that and a few time slips would put it to rest.

hell, I'm not in the market for heads for about 2 more months. I just hope some more people try out TEA's so I can make a good decision.

I've shopped around and ordered my TEA heads today. The difference in price left me enough money for my TCI tranny.

Re: Whats better TEA or GTP

Choosing a cylinder head company now seems like a game of Follow the leader. Cartek and GTP were probably the first 2 vendors to place cars into the mid 11s and now high 10s. If you take that experience coupled with flow bench readings you can tweak your model to net the best gains. LS1tech was the first place that I heard about TEA heads so it might just be a case of needing to get their heads onto a hardcore drag car and see what it does. Being a hardcore dragracer if your looking for the most gain 9 times out of 10 you dont consider cost. Those last 10th are more important than costing 1700 more. We will see what the TEA heads end up putting down(tuned) in the next few weeks and see how that compares to Cartek and GTP. Cartek is making 450/410 with a cutout on 4.10s. Lets see where TEA ends up.

Milling is free and he flows every head, and the $350 core charge is the same as if you got 5.7L heads...
