Heads and cam dyno numbers inside...

[Tom86ZT]

Hello all,
We just dynoed Mike D's 2001 Sapphire Blue GTS, one of our SMS racing customer cars after we installed BTR stage 2 heads and cam (thanks Tom Welch).
Full list of mods include:
BTR stage 2 ported heads,
Comp Cam
1.7 roller rockers
Headers/exhaust

Well, to say the least the car made great power and torque
numbers are 517rwhp, and 560rwtq. This car made and increase of approx. 100rwhp and 110rwtq. Mike the owner describes the car afterwards as, "exactly what the car needed". We will be heading to the track on sunday and see what the new numbers give us.

SWEET!

Wayland....howz about them valves now...??

Nice numbers guys!

What track do you guys race at??? I didn't realize head/cams could yield that much power.

 

[DRBSRT]

J Dawg............Heads and Cam packages can definitely yield that kind of increase in RWHP & RWT. In fact, I was over at RSI in Houston this afternoon and had the pleasure of watching one of there new packages, the RSI 600 package, on the dyno. This '02 Viper had headers, exhaust, T&D rockers and, get this, HEADS ONLY........NO CAM!!! The dyno results showed 528 RWHP and 533 RWT....... and that's with 3:45 gears!!!!! Don't know who the owner is, but he will be one happy camper!! I have also witnessed at least four other RSI Heads & Cam cars (RSI 650 package) dyno around 570 RWHP and 580 RWT........Awesome numbers!!!

What options do we have on buying head and cam packages ?

 

[Maverick The Electrician]

Almost every tuner has a heads and cam package. Get one that best suits your needs.

 

[Tom Welch]

Maverick is correct........your personal requirements... items like drivability, performance, forced air, Nitrous, available gasoline quality, emissions, maintenance interval and many other factors should add up to what you are looking for.

I personally like something in the "520 ISH" RWHP range on a 488 ci engine. The correct camshaft with this combo will net excellent results on a simple nitrous system(well in excess of 750 RWHP and 900+ RWTorque) without compromising drivability.

Best of luck in your search. Feel free to check our website for assorted head/cam packages or give us a call or email for more information.

Can you make 700 RWHP safely in a cast piston car ?

 

[Larry Macedo]

Can you make 700 RWHP safely in a cast piston car ?

700RWHP normally aspirated on cast pistons? S/C? Nitrous? I built an 01 utilizing BTR Heads, BTR N20 Cam and BTR 2 Stage Nitrous which made 693rwhp and 870rwtq conservatively tuned because of the cast pistons.

 

[FranciscoR.]

Does the 94 RT/10 have forged or cast pistons? Also, can you get these head / cam packages for this year RT/10 or is it just for gen II and above? ( I would imagine if you could, you would get roughly the same amount of hp increase??? )

 

[HouseofSpeed]

Head and cam numbers with exhaust components can easily hit the mid 500s....

I don't see a low 500 number being that impressive really.

We dynoed our Gen1 643Hp and 663 torque with a Moderate Head/Camshaft/Rockers/Headers combo.

 

[FranciscoR.]

That's RW numbers? Like when I get my RT/10, I don't need to turbo or super right away to get some serious numbers?

 

[jp]

FranciscoR. If you have my post in mind, it's Flywheel power.

 

[FranciscoR.]

That's still pretty damn impressive though isn't it? To me that's a whole lot of power....lol

It's actually built for Nitrous, but the race series we are running doesn't allow Nitrous. 10.70 all day on motor.
The heads are wery well designed, with a lot of flow "under the curve".
