what are the highest rwph and tq from heads/cam setups???
APEX's LETHAL 650 package primarily consists of heads, cams, and rockers. There are many other parts included to enable the car to handle the power reliably, but the dyno's I have seen have been in the 550-575rwhp range with cats, etc... You can definitely get more power than this, but you will...- LTHL VPR

Special! APEX custom high-flow fuel injectors!
These injectors really flow!!! Actually, they are slightly more than 40lbs/hr... and can EASILY handle 700+ rwhp. Because APEX had them custom made to their specfications, each one was tested and spec'd prior to shipping by the manufacturer. I guess that way you can be sure they will be...- LTHL VPR

792 rwtq at 3400 rpms!! Further testing of the LETHAL 1000
Now, I know what you are talking about.... I have stock rear end gear ratio which is plenty fine for the power I am making. The car spins up fast; the aluminum flywheel helps in this department too. Light throttle blips can easily hit high rpms even now... Once I receive the injectors and we...- LTHL VPR

792 rwtq at 3400 rpms!! Further testing of the LETHAL 1000
I can't wait to get everything dialed in too!! Actually, we made those numbers on less than 4 lbs boost! We didn't hit 4 lbs until around 3800 rpms. I did have a chance to drive it already. I don't think it lost much in the low end, off the line, but I wasn't dropping the hammer either. I...- LTHL VPR

mph on a viper h/c package ...
I think your goals/restrictions will play a factor in your outcome... Do you need to pass smog/emissions? Will you be driving your car on the street? A good heads/cam, full exhaust package can bring you safely into the 550-575 rwhp range. Just for reference: My 2001 ACR (stock) dyno'd...- LTHL VPR

What is the secret for APEX regarding their quick 0-60 times
If you are referring to the LETHAL 750 package tested by Car and Driver in the annual Supercar challenge last fall, I was even surprised that were were able to accelerate faster than the $225k 750hp Porsche all-wheel drive turbo. In fact, my car was the fastest production car 0-60mph to finish...- LTHL VPR

792 rwtq at 3400 rpms!! Further testing of the LETHAL 1000
Well, as we wait for injectors, I decided to spend some more time on the dyno today and tune the car in the lower rpms where there is plenty of fuel to play around with. Surprisingly, I was quickly able improve upon the numbers from earlier this week. Here is what I was able to accomplish...- LTHL VPR

Anyone using a fuel pump booster???
APEX played around with these on a few Vipers in the past. It worked OK, but it was very limited in how much fuel would actually be added. In addition, it can overwork your fuel pump, causing it to heat up. It all depends on how much your fuel system is taxed now. -Wayne- LTHL VPR

Re: Today\'s update on LETHAL 1000 dyno testing/tuning... Ben- I am not as familiar with Supras; although I did tweak my 93 Rx-7 TT R-1 edition #4 back in 1993. The Vipers run a MAP type setup, not a MAF like on Mustangs, etc.. I remember APEX recently tuned a MAF Mustang perfectly with 83lb...- LTHL VPR

Re: Today\'s update on LETHAL 1000 dyno testing/tuning... Ben- Thanks. I don't think they can custom make us Viper style injectors for that kind of flow (to support 1200 hp).... At that size, it may be difficult to trim enough fuel out at idle/cruise without running into issues.' I am hoping...- LTHL VPR

Today\'s update on LETHAL 1000 dyno testing/tuning... Well, today we strapped my Viper down for some dyno testing/tuning.... Looks like we were running out of injector at around 4000 rpms. Just for fun we tuned the car for fuel and timing up to 3500 rpms. The results looked great. Looks like...- LTHL VPR

Motor Only RWHP Numbers
Very interesting question, but the replies could be misleading... There is 'much to think about' when you are saying all motor RWHP numbers. Are you speaking about peak numbers or average rwhp numbers. Are you talking about pump gas or race gas. Is the car set up for the street (good...- LTHL VPR

Torquemonster- We have used the Aquamist system on cars before. On a car running with high boost, this could make a noticeable difference. We installed an aquamist system on my Viper about a year ago (pretty trick; it was hard to see) just to play around and see if it made a difference. We...- LTHL VPR

Larry- You are correct. The injectors we use are manufactured from scratch. We can order them for almost any flow we want and they 'pop' in the stock intake without adding external fuel rails.

J Smith- The numbers for motor only were around 650 rwhp and 690 rwtq.
