no one running mach 5's???? what about mach 6's same questions

Moules

i hardly see any mach 5's on signatures but you will find alot of mach 4's. there very streetable and towable with a small turbo. egts and mileage is very nice for a 150 hp injector.

My truck works pretty good with just the mach 4's and other have done even better than I.

I went from 4's to 6's when I put the twins in. 4's are very streetable, 6's, not as much; you have to really pay attention to the throttle not to black the whole intersection upon acceleration. I lost just under 1mpg with the 6's compared to the 4's, and that's in spite of driving more gingerly now. I would say get the 4's unless you are shooting for maximum horsepower and intend to get twins. I can't even imagine driving a truck with 6's and a huge single...

nice numbers for a small single. is ur pump a hrvp?

Destination

i was planning on 4's but saw a few adds in the classifieds for a set of 6's and a set of 7's but if I can't daily drive with them then i wont git them. im also going to be gitting a 62/71/14 here preety soon so what do you think will compliment that turbo the best. i want to be able to tow and be competitive sled pulling and be a daily driver.

Unless you are going with twins you will not like the 6's. I run them daily and like them. The smarty revo made them way more driveable and I can still get around 19mpg if I drive like I have some sense.
I did run them with a big single for about a week while I was changing my twin setup and having the ht3b reworked ,and it was no fun at all unless you really like to smoke everywhere. Once the single lighted woo hoo, but by the time it did the egt's were already too far gone to get back on top of them.

Yes it is, from II.
I think mach 4's and a super 62 are pretty good all around combo.

I got a set of 5s in a 01 with a single. Not gonna tow with them. They are smokey and hot when daily driving. If your towing id say the 4s will be your ticket. There are guys making some sick numbers with mach 4s on here. They seem to be the best injector for the best of both worlds( drivability and competition).

Destination

well i want to be able to tow with it so i will pobably git the 4's with the 62mm turbo. thanks for the help guys

I daily drive with 5's and twins of course... I have no idea what kind of dyno power it makes but I know that I don't need my TST box to scare people.

As for my fuel mileage, I actually think it's better now than when I had the DD3's...

i averaged 18-19 driving 85+ this week. with mach 4's and 62/71/13ss.

i get 16-17 around town.
