Let me clarify the issues with the "stolen cylinder heads", they were mine. sure would like to know when Ned is going to pay me back the money he owes me for the Gen 3 and AEM that I "sold" to him? He has owed me the money for over a year and when I go to collect he BS's me around.
I id get another set of heads made, but never installed them. Flow numbers were lower than the previous heads and other issues.
In reference to your statement that your new heads have lower flow numbers than your old heads, since you decided to bring this matter up on this forum in a manner that has a negative connotation directed at me, I would like to remind you that the original statement you made to me about this matter was that your heads did not flow as much as another set of Viper heads that I also ported for another customer. This is why I have the right to question the integrity of this comment since there is a misrepresentation of facts, your original statement to me was that your Viper heads do not flow as much as another set of Viper heads that I modified for another customer and NOT that your new heads do not flow what your old heads flowed. In fact, I did not provide you with flow data for your old “stolen” heads, so there is no foundation in fact for you to make such a comment about the two sets of heads that you owned. Once again I am dealing with baseless comments on this forum which I am continuing to prove redundant. So my next question is what your motive is for making this false statement and who encouraged you to do this? The timing is also rather strategic, right after I am having constructive dialogue about our stoker motor making 725 hp with our modified Viper Street Performance head this new false statement appears on stage with a negative slant about our heads. Interesting tactic and a good political attack!
It is also important to mention that you did not acquire any cylinder head flow data from me. This cylinder head flow information regarding the two set of Viper cylinder heads that I ported for you and your friend was given to you by another shop that you and your friend are attending to service your Viper engines. What you also stated to me was that your friends Viper engine blew up and broke after the Viper engine was rebuilt at this other shop and you also stated that you were still waiting to have your engine built at this other shop after some determination had been made as to why the other Viper engine failed. So I want to clarify that when you state “the heads have not been installed” and “other problems” this has nothing to do with our business since you are now dealing with another business to service your Viper engine. Let me make it clear that you had your Rolling Thunderz cylinder heads and cam originally installed back in 2006 and you reported no problems with our engine modifications until the stolen cylinder heads issue surfaced, several years later. It is also important to mention that Rolling Thunderz has not serviced your Viper since 2006.
Next point, you and your friend delivered several Viper engine assemblies to RT two years ago to have Viper engines built and it was determined by us that the Viper engine components that you delivered for a rebuild consisted of worn out engine components and damaged engine parts, which in our opinion were not suitable for a professional engine assembly. We highly recommended that aftermarket pistons and connecting rods be used for your Viper engine assemblies and our recommendations were not accepted and we were instructed to use the best components from the used production engine assemblies to reassemble one engine. Then we received communication that the rest of the engine components that belonged to you would be picked up by the other shop that you had decided to service your engines and this never happened. You stated to me that both you and your friend have elected to have your Viper engines built at another shop and the reason you gave me is that this other shop had built a Viper road race engine that had success in regional competition. What makes no sense to me is that you know that Rolling Thunderz builds Viper race engines that compete in GT3 race competition that win races in international race competition. Since you advised that your Viper is still not ready, which is now 17 month after we prepared your new heads; this convinces me even more that what we do at Rolling Thunderz is very special.
On that note, since you stated to me that your actual concern is your heads do not flow the same as your friends heads, let me address this issues. Allow me to remind you that when you and your friend came to me and requested that I modify both your Gen 2 Vipers; your specific requirement was that both of your Vipers have the same level of performance. I would also like to remind you that your friend has made numerous compliments to me about how I developed repeatability with these engine programs where both Vipers perform the same during race competition. You yourself have mentioned that you are equal in competition so in my opinion we delivered exactly what you both wanted us to deliver and the performance of these Vipers was highly successful by all accounts, including your own. At least your friend actually appreciated how difficult it is to develop two engine programs that deliver the same level of Viper vehicle performance. What you do not fully comprehend is how complicated it actually is to make both your Vipers perform equally during race competition, so allow me to explain. Technically, it is important to mention that an ACR Viper, which is what you have, is lighter than a regular GTS model, which is what your friend races. It is also important to understand that the weight of the owners/drivers must be taken into to account in order to determine the right power to weight ratio for both Vipers. What this all means is that since you and your ACR Viper were close to 200 lbs lighter than your friend and his GTS Viper, his engine needs to develop more performance in order for both vehicles to deliver the same race track performance. I hope you now understand that this was a much more complicated development project than what you actually think, since the two Vipers had a significant variation in full race weight, which is why the engine performance had to be developed differently for both Vipers to deliver the same on track performance. The obvious part of this equation is that an ACR was developed to be lighter so that it can perform better and since you are significantly lighter as a driver, these dynamics must be considered in order to fulfill your request that both Vipers perform the same on the track. If you review the Mustang chassis dyno data that you were originally provided back in 2006 you will note that your friends Viper produces approximately 25 more RWHP. So when I am requested to develop the same vehicle performance for two different vehicle weights, I do not conduct the same modifications to both engines. This is another one of our great success stories and not a problem as you have projected as a variation in cylinder head airflow. It is actually an even greater success story when you consider that our Rolling Thunderz Gen 2 Vipers were actually outperforming the new Generation 4 Viper ACR, which is clearly documented in correspondences that you and I both received from your friend and fellow racer of events that unfolded at the race track where he was running just a little bit faster than the Gen 4 Viper ACR on the straight away. So not only did we modify two Generation 2 Vipers, to perform equally with different vehicle race weights, these Gen 2 Viper engines that Rolling Thunderz developed were able to out perform the new Gen 4 Viper ACR when it arrived on seen, as documented in correspondences that you have received. It is also important to emphasis that these Gen 2 engines still had stock cranks, rods, and pistons and that this remarkable performance was achieved with only our Phase 4 heads and custom V10 Viper cams, along with a complete Belanger exhaust system.
To conclude this chapter, more modifications were performed for your friends Viper GTS heads in order for his heavier vehicle weight to perform at an equal level of performance with your significantly lighter ACR race weight and thank you for confirming that your request and our target objective was reached with both Vipers performing equally in race competition. In fact, this matter is actually another very significant Rolling Thunderz success story. What I was requested to provide was equal Viper vehicle performance and not equal cylinder head flow numbers, which is why you never received any flow data for either set of heads from me and why there should be no concern about two sets of heads performing equally. Furthermore, I also stated to you that if you want me to do more work to develop more performance for your new Viper heads that I would be willing to do so and you declined this offer. So why make a post that has this negative connotation about our Viper cylinder heads, on this thread about “who has the best heads”, and why is there a misreprentation of facts?
