UnderPressureGT said:how could you compare the two?? they are both good for the money, and thumper does make some kick ass heads... but you're comparing a stock ported head to a head that flows near the same as AFR 185's... no comparision.... i would get the PTL's in a heartbeat.... I have them right now on my new motor; the aluminum 2.05/1.6 180cc heads that i picked up for 880 shipped... I cant say i have any problems with them.. My car is pretty damn quick..
ms93gt said:LOL well you can't compare protopline to afr either. Compareing them to world would be better.
ms93gt said:Well I dunno much about protoplines so maybe someone else will chime in but what I do know is that afr's are PROVEN to make power. Also I know protoplines weigh a lot and on there site it only shows what the intake flows. Wheres the exhaust? Afr's are the cream of the crop out of the box head, many many people use afr. If protopline were that good then everyone would be using them.

90mustangGT said:Well, who's running pro-toplines and what are they running? I remember they first came out aka Jegster heads and there was all this hype, then people were having all kinds of problems with them and spent so much getting them fixed that TFS's or AFR's would have been a better deal. Then heard hardly nothing about them after that. Saw a few dyno's and I wasn't too impressed, but maby I was looking at the wrong one's. So who's running PTL's and how do they compare to AFR's and TFS's with otherwise similar combos?
I'm not bashing them, just straight up, lets put on the proof.
$880 is damn cheap, almost too cheap. That is usually what bare castings cost for most aluminum heads, and here these are fully assembled and such? So either someone is cutting corners or someone is just cutting a profit.
Thumper heads are as reliable as stock because that is what they really are, just ported. Factory reliable, won't mess them up unless something really goes wrong, and they are strong performers. I ran 8.4 at 85mph in the 1/8th with them launching from idle on a worn motor. Have TFS waiting to go on the new motor.
Curse said:There was a guy on here that tested the PTL independently, he had his own website. Anyone know who I am talking about? Had very impressive flow numbers.
ms93gt said:Well curse if you claim they were so good but yet went out of business then it looks like they sucked. No "great" head will go out of business. Look at gt40's, tons of better heads but they're still selling like candy.
