Guy, I am suprise to see you posting at this time, since you usually post between 12:00 - 3:00 A.M Quick question for you. Do you think that there will be any trial and erros with porting the soon to be realeased FAST 102 LSXR for the LS3, or will it be like porting the 92? I noticed that you posted that you have honed your porting techniques as time goes by, which is understandable, but was wondering if time will be needed to find out what type of porting works best for the new manifold?

 

An note about the rear graft install: Some manifolds were done using Automotive Goop in the red bottle. I dont know which customers had this type used. It apparently has a different temp threshold than the normally used purple Goop. The issue has raised some questions and has led me to realize that since I have seen and repaired manifolds that had 2 part epoxies crack due to different thermal expansions, that I dont feel comfortable relying on any adhesive to hold the graft in place. All manifolds done now will have an internal brace that uses screws to hold the graft in place and an epoxy only to fill in for an air seal. Its overkill but I dont want any room for doubt from now on. Anyone wanting this new fix can send me the manifold for a free update at my expense. There wasnt much by way of profit with donations in the equation but I dont feel its right to have a doubt even if its a loss financially so I have to do this and make it available to anyone who feels they may have been affected. Affected manifolds would have the glue bulging in the back of the manifold in the graft area and it can be seen if the throttle body is off. Scans of the car would show big positive short term fuel trends. I'm sorry to those affected but I will do whatever it takes to make it right. Newer manifolds will be immune to this issue.

 

Excellent way to do business Guy, and if I ever upgrade, you will do the porting for me, without a doubt. I know it sucks to lose money on a job, as I have done the same, but in my experience, it repays in spades. I've had a few stripped C5 calipers (always the threads on the front right banjo fitting) and 3 bad seals. I always reimburse the labor and replace the part, as the customer shouldn't have to. I think we are much alike, in that we know what its like to have a mod go wrong and be disappointed, and don't want our customers to have the same.

 

I started this as a charity venture due to losses in my life. I dont run a company and charge little, make friends and pay for R&D fun with anything left over. God presensts solutions but St judes wont have to refund anything.

I already have gotten responses from customers that shrugged it off and offered to cover shipping because of the circumstances. If I have to, I will even travel to fix it. No one will ever say I turned off the phone and skipped town to not have to make it right. My name was built one day at a time and I dont mean as a forum guy, I mean as a human being. I will always do whats right and thats the best reason to have a dealing with me with corvettes or with life in general.

Gary (Siffert) thanks for being one of those easy to talk to guys. I promise you, in the end you will have a 10 sec car and it wont cost you much when you see what I will do to make someone happy. You made a friend.

 

I would recommend to change that to read "scans of the car while idling for a few minutes show big positive short term fuel trends ranging from +20 to +55 thus indicating a vacuum leak."

Thanks for making it right and responding spin FAST to a customers concerns and problems. Though I'll pass on the 10 second car, I dont want to put in a roll bar , I'll be happy with a 11.50

Sir-
Can you email me info on the best intake you can provide me for the mods I have listed in my signature. What would the cost be, Time line ,etc.

Thanks
G

As Linc would say in the show The Mod Squad....."Solid"!

 

Dude you are showing our age

 

 

you too

 

I'm somewhat surprised you're at 418/381 with your mods. I certainly realize all dynos are different but that seems quite low to me. Anyone else feel that way? I would talk to Spin for sure about his ported FAST but you should consider your tune as a source of lost hp/tq. I have stock heads/cam and dynoed 395/387. Just a thought.

 

I have always thought so as well..... With the Mustang dyno it's not all that unusual to be 10-20 HP lower. When I do the Fast & retune, I'll do a before & after with a different dyno
G

BTW- When I did the mods it was right at 100hp increase with before/after dyno. I know alot of guys with stock was getting around 340 RWHP on other dynos compared to my 320 RWHP. Regardless of what the machine says I know I picked up 100 new horses to the wheels doing the mods.

 

Guy
got my manifold today, it looks great.
Thanks

Yep nice gains there. Spins Porting & mods has done much for so many.
I know on mine (BOLT ON ) there are some points along the dynocurve
where we got as much as 40 rwtq.

 

I will be real happy with that!!!!

 

He has an automatic and the A6 will show 20+rwhp less on the same dyno. Your M6 is always going to dyno more with a given mod. The dyno should be used as a tuning tool to compare the same car on the same dyno before and after installing a mod and tuning. Doing 4 consecutive pulls will make more power on each pull and can be 8hp more from the first pull. Maintainance and set-up can greatly alter the reading too so using a dyno pull from months ago will vary the results too. Comparing what car A did on dyno A isnt a fair comparison to car B on dyno B especially when 10hp can break an ego.

I have seen my fair share of guys get happy dyno results of 460rwhp with a cam and stocj heads then swap out a given mod that gets 20-25rwhp at peak only to see 16rwhp and get sad. The reality is the baseline was a happy baseline and didnt reflect reality....they then got 4mph faster on the track which verifies the results were stronger for the mod than the dyno indicated or in more simlple terms the baseline was reading too high and the final number reflected the true power but left the owner thinking he didnt get as good a gain as he really did.

Go by the averages with things like this manifold. If 80% of guys see 20-25 at peak and 30rwtq under the curve then expect that. I dont put much faith into guys seeing 30rwhp+ at peak nor do I cry when a guy says he only got 16 at peak and 25rwtq under the curve.

I port these things the same and there isnt going to be much variance. I go slow and do each one as if its for my car. same goes for any work I do. Every bolt is cleaned (as is the bolt hole) and I TQ each one with a TQ wrench to spec. Lock tite anything that can come lose and the added effort results in great reliability. I'm not fast on head/cam installs but they are always done as best I can do them, meticulous to say the least.

 

Guy
got the manifold.
looks great and works!!!!!!!!!
no LTFT in RED!!
