trick flow track heat or street heat

90blackstallion · Oct 5, 2007

Hi everyone I am new to stang net and hope that I can get some input.
I've got a 90 gt 5.0 with gt 40 cast iron heads, 70mm tb, 19lb inj, 73mm vortex mass air, 1:6, 1:72 rockers staggered, b303 cam, adj fuel reg, 155 fuel pump, mac headers and h pipe, flowmaster exh, undrive pulleys, bbk cold air kit ,3:73 rear. dont really plan on running it much at the track. more street driven. should I go with the trick flow track or street heat?

With that combination, go with the street heat with the 15" runners

The track heat likes a bit more rpm that your engine is not quite ready for.

Good Luck.

street heat FTW

i kick myself in the ass for even going with the track heat, wish I got an RPM 2 honestly.

grey5.0beast · Oct 6, 2007

I've never heard of staggering the RRs, why would you want to do that?

90blackstallion · Oct 6, 2007

do you think that I am going to lose any power by going with the track heat? the reason that I say this is what if I ever decide to put a supercharger on.

youll lose low end and mid range

Aliate X · Oct 6, 2007

this is another thread that falls into the category of 4.10s are unstreetable, and nitrous will blow your motor up.

I OWN the track heat manifold and yes maybe i lost low and mid range horsepower, maybe about .5hp. The track heat is still a very MILD manifold. It is only designed to pull to 5,500. Id be worried about losing low and mid range with something like the RPM2 which can pull to 6,500-7,000rpms. Any mods you do to your car youre going to loose low and mid range, unless youre towing boats with your mustang, you shouldnt care.

Im not trying to call you out or anything 89saleen, I just think that the name of this product is very deceiving, this is a very mild manifold.

aliate hit the nail on the head

The track heat is designed for 1,500-6,500 RPM.

If you are going with a supercharger, go for it.

Shorter runner promotes higher rpm, or needs to be combined with a longer stroke engine (5.315"-5.400").

Longer intake runners promote better cylinder fill, and therefore a more torque feel in the lower rpms.

A street heat or track heat are not unstreetable, but that does not mean you need an intake because it is not 'unstreetable'. Match your combination for now, but if you plan on boost in the soon future, go with the track heat or similar.

Aliate X · Oct 7, 2007

hmm thats news to me lol I always thought the track heat was supposed to pull to 5500...oh well Id still rather have a systemmax or something

5spd GT · Oct 7, 2007

That is the street heat

The Systemax is a good intake, with the combo to match

What you gain up top, you lose down low. Somebody suggested the RPM 2 over the track heat. According to MM&FF the RPM 2 gained almost 20hp up top over the RPM but it also lost it down low. In a heavy car that wouldn't be good, but a fox can stand to lose some hp down low.

I know that Ed Curtis told me to go with a Performer (idle-5,500) because it has a more useable powerband. That was asking him, if I should go with an RPM intake.

90blackstallion · Oct 8, 2007

do you think that I should go with a different intake instead of the trick flow? if so the rpm2 or the systemaxx or the edelbroch performer

Heres a better question, do you every plan to buy a power adder? If you plan to stay N/A then do this, according to dyno results....

I'd buy the Edelbrock Performer or Performer RPM over any TFS intake. Now the RPM makes 10hp more at 5600 rpm but looses 10 hp down low compared to the performer.

BUT, if you want a intake that will spank all over those....buy the Systemax 2 intake. Its got a little less low end but over 23hp more on the top end. And its great for Blown and N/A. And just for an idea. With my 347 blown stroker. I'll make over 700 rwhp with the Systemax 2 and the only change is i'm grinding the tb opening to 75mm. I'd go to a box and pick up 40hp but i can't due to hood clearance.

Peak power does not mean much in terms of beating that guy beside you

You want nice average power and a more useable power band.

A Holley intake is not something I would run on an N/A 302/306, UNLESS it was a track dedicated car or you want to turn some rpms, more-so than the rev-limiter.

The Performer RPM is no longer in production.

I think the Street Heat/Performer is a nice combo for a 'under 6,000 rpm' engine, or even a ported gt-40 intake (no longer made either).

If you are planning on boost in the near future, a Systemax/Track Heat/RPM II, are not a bad idea at all.

I have to question where your getting your information from? I understand that its your "thoughts" that you wouldn't put a holley systemax on a n/a 302 306 under 6 rpm, but i mean do you have any dyno #'s that your going off of? Or are you just judging by rpm range? Because i have proven dyno results that clearly show that a holley makes more hp then your suggested performer intake, EVEN below your suggest 6k rpm range... Its not really hp your losing, more of torque your losing in the lower rpms, but in the higher rpms the Systemax smokes it in hp and torque. But remember, what you gain up top, you lose down low. Its that simple.

This dyno was performed on the same engine, 306, 30 lb injectors, Pro-M 77mm, 75mm TB, custom camshaft, TFS twisted wedge heads, and 1 5/8 lt headers with 3 inch exhaust. So its your basic H/C/I setup.

Id rather have high rpm power than bottom end power, loss of bottom end power can aways be negated with the correct rear end gear ratio.

MustangOwner · Oct 8, 2007

oh wtf? okay i must have put in the wrong picture lol. thats a good gt 40 dyno ain't it? lol. anyway. Yes you can stand to lose the low end when your car is a light 3000lb mustang. I mean think about it. When your out on the highway and you do a pull.... your in the higher rpms. Thats where you want the power anyway.
