I do more reading then I do posting on here, however I can't seem to find everything I want to know no matter how I spread my reading. I will start this out with my mods to date, as this may help with part of my question which is my potential ET. I have a LID, HPP3 which I assume I will have to rework to take out the HT parameters (as far as timing advance and what not that it may do to "help your car perform better") but I need it for calibrating the 4.10's I have... Next mod is obviously 4.10's, I have a Y pipe on there however I have LT pacesetters waiting to be put on, but first I have clamps, OR Y pipe and O2 extensions on order... when they come they go on. I have a Magnaflow exhaust otherwise, short throw (hurst) ((its an M6)) I have a Granatelli MAF, but I don't think alot of this is going to come into play a whole lot... I do have a new set of Nitto 555r EDrag's on it now so hopefully traction won't be too bad, but I have to admit that if I even launch at like 1500-2000 rpm I lose it traction wise. I havnt used them on a preped track though, and havn't really heated them up too much before launching (line lock is on the way) ...

Ok, down to business now that I have bored you quite a bit... I plan to get a HSW sudden impact kit on either a 125 or 150 shot. I also planned on getting a window switch with it along with running it on first gear lockout for a little help... I assumed maybe shooting from 3200-5500 would be acceptable... I was also looking at plugs obviously, maybe a heater, defintaly a purge system ... and possibly HSW's ashtray switch set... its nicely laid out and saves me space... ok, so.. with these items... Am I basically safe to do what I set out to do (125-150 shot) ... and if nothing else is needed (ie, i dont see the need to shoot progressivly unless absolutly necessary) what in all of your expierence would me ETs look like... I can say that last I ran I pulled 13.4 on the third run with that car... spinning alot of 1st, most of 2nd and some of 3rd.. I know I could have done much better if I had the DR's then but even alot better than that even on the street tires if I just had more runs...

So take into consideration my mileage, the fact the engine and drive train are very solid, the kit I am looking at and the options I am using with it. My current modifications and help me make a prediction of the ET along with the reliability and usability of the nitrous setup I am planning on using... Along with any suggestions...

Thanks in advance, and sorry for the long post.

 

You should be okay, it sounds like everything is in proper order. On the wet kit on a 125 shot right around a second. Here is one post I found, he's a dry shot jetted to a 100 shot:

You can also do a search for 07BlueDevilZ06, he's been progressing from a dry shot to wet to dual stage wet and documenting his times and such. He's really cooking now!

I don't have the HSW kit (wish i did) but I have a very stock 99'ss that has a 125 shot on it and it will run a 7.89 in the 8th. With the mods you mention I would think you could be in the high 11's with traction.

 

Ok, I see you have 42# injectors though, am I looking at needing those as well.... I understand I am probably opening pandoras box of opinions here... I have read a mix of both which usually leads to some kinda of clash of opinion... But I am more looking for fact... Is it needed, or does it run fine with out them... I am still undecided on 125 or 150 as well... so keep that in mind.

 

If you go the wet route you won't need injectors, that is if your current injectors are okay with your NA set up.. Being that you are mostly bolt ons you should be okay on a 125 - 150 shot with the stock fuel pump also.

Well now that I have done it, I can tell you that the stock injectors do max out quickly. I was running the 125 dry shot and was ok afr wise until I bumped it to the 150. It was leaning out something nasty like 15:1 at about 5,000 rpm. Needless to say I stoped that immediately. I really wouldn't go over a 125 and even then you need to keep a close eye on your AFR, keep in mind I have no other mods than a lid, and that is why I think my injectors could keep up...resonably on the 125. I put in the 42# injectors because I am about to install the MS4, longtubes, and various other mods and wanted a chance to tune the injectors without the other mods disrupting my ability to learn how to tune with HPT. Now that I have tuning time under my belt and have a small grasp on it i feel I am ready to proceed further with mods. Really if you don't plan on doing more mods other than exhaust and gear I would definately go with a wet kit and leave the stock injectors. In my opinion it will be a MUCH easier way to keep the car tuned properly. The stock injectors can handle those mods easily and with a wet kit all you do is change the jetting and you can fly without re-tuning...hope that helps!
